Part 8: OS command execution using sapxpg. Somit knnen keine externe Programme genutzt werden. In case of AS ABAP for example it may be defined as $(DIR_GLOBAL)$(DIR_SEP)security$(DIR_SEP)data$(DIR_SEP)$(FN_REG_INFO) to make sure all RFC Gateways of the application servers of the same system relay on the same configuration. They are: The diagram below shows the workflow of how the RFC Gateway works with the security rules and the involved parameters, like the Simulation Mode. Part 7: Secure communication After an attack vector was published in the talk SAP Gateway to Heaven from Mathieu Geli and Dmitry Chastuhin at OPDCA 2019 Dubai (https://github.com/gelim/sap_ms) the RFC Gateway security is even more important than ever. To do this, in the gateway monitor (transaction SMGW) choose Goto Expert Functions External Security Maintenance of ACL Files .. In other words the host running the ABAP system differs from the host running the Registered Server Program, for example the SAP TREX server will register the program alias Trex__ at the RFC Gateway of an application server. Here are some examples: At the application server #1, with hostname appsrv1: At the application server #2, with hostname appsrv2: The SAP KBA2145145has a video illustrating how the secinfo rules work. Maybe some security concerns regarding the one or the other scenario raised already in you head. Part 5: ACLs and the RFC Gateway security. The default value is: gw/sec_info = $(DIR_DATA)/secinfo gw/reg_info = $(DIR_DATA)/reginfo In addition to these hosts it also covers the hosts defined by the profile parameters SAPDBHOST and rdisp/mshost. The RFC Gateway allows external RFC Server programs (also known as Registered Server or Registered Server Program) to register to itself and allows RFC clients to consume the functions offered by these programs. Please note: In most cases the registered program name differs from the actual name of the executable program on OS level. Example Example 1: As we learned in part 3 SAP introduced the following internal rule in the in the secinfo ACL: Alerting is not available for unauthorized users, Right click and copy the link to share this comment. The following syntax is valid for the secinfo file. Every line corresponds one rule. Furthermore the means of some syntax and security checks have been changed or even fixed over time. Thus, part of your reginfo might not be active.The gateway is logging an error while performing name resolution.The operating system / DNS took 5 seconds to reply - 5006ms per the error message you posted; and the response was "host unknown".If the "HOST" argument on the reginfo rule from line 9 has only one host, then the whole rule is ignored as the Gateway could not determine the IP address of the server.Kind regards. D prevents this program from being registered on the gateway. Darber hinaus stellt die dauerhafte manuelle Freischaltung einzelner Verbindungen einen stndigen Arbeitsaufwand dar. The secinfosecurity file is used to prevent unauthorized launching of external programs. Save ACL files and restart the system to activate the parameters. The RFC library provides functions for closing registered programs. Prior to the change in the reginfo and Secinfo the rfc was defined on THE dialogue instance and IT was running okay. The RFC Gateway act as an RFC Server which enables RFC function modules to be used by RFC clients. This opensb the Gateway ACL Editor, where you can display the relevant files.. To enable system-internal communication, the files must contain the . Evaluate the Gateway log files and create ACL rules. This is for example used by AS ABAP when starting external commands using transaction SM49/SM69. For this scenario a custom rule in the reginfo ACL would be necessary, e.g., P TP= HOST= ACCESS=internal,local CANCEL=internal,local,. Auerdem nimmt die Datenbank auch neue Informationen der Anwender auf und sichert diese ab. USER=mueller, HOST=hw1414, TP=test: The user mueller can execute the test program on the host hw1414. Part 4: prxyinfo ACL in detail. Default values can be determined from the aggregated Gateway logging and used to assemble control data, and subsequently leverage the control data content for further use. This publication got considerable public attention as 10KBLAZE. After implementing this note, modify the Gateway security files "reg_info" and "sec_info" with TP=BIPREC* (Refer notes 614971 and 1069911). so for me it should only be a warning/info-message. there are RED lines on secinfo or reginfo tabs, even if the rule syntax is correct. RFC had issue in getting registered on DI. From my experience the RFC Gateway security is for many SAP Administrators still a not well understood topic. The Stand-alone RFC Gateway: As a dedicated RFC Gateway serving for various RFC clients or as an additional component which may be used to extend a SAP NW AS ABAP or AS Java system. You have already reloaded the reginfo file. In these cases the program started by the RFC Gateway may also be the program which tries to register to the same RFC Gateway. When using SNC to secure RFC destinations on AS ABAP the so called SNC System ACL, also known as System Authentication, is introduced and must be maintained accordingly. Part 1: General questions about the RFC Gateway and RFC Gateway security. This is because the rules used are from the Gateway process of the local instance. To prevent the list of application servers from tampering we have to take care which servers are allowed to register themselves at the Message Server as an application server. The local gateway where the program is registered can always cancel the program. The default value is: gw/sec_info = $(DIR_DATA)/secinfo gw/reg_info = $(DIR_DATA)/reginfo A general secinfo rule definition would be (note that the rule was split into multiple lines for explanation purposes, so it is more easily understood): Only the (SAP level) user IDs BOB and JOHN can start this program, and they will be logged on to one of the instances from this SAP system. Only clients from the local application server are allowed to communicate with this registered program. Always document the changes in the ACL files. Part 5: Security considerations related to these ACLs. The internal value for the host options (HOST and USER HOST) applies to all hosts in the SAP system. The name of the registered program will be TAXSYS. This is for clarity purposes. open transaction SMGW -> Goto -> expert functions -> Display secinfo/reginfo Green means OK, yellow warning, red incorrect. Part 4: prxyinfo ACL in detail. In an ideal world each program alias of the relevant Registered Server Programs would be listed in a separate rule, even for registering program aliases from one of the hosts of internal. The parameter is gw/logging, see note 910919. Read more. Dieses Verfahren ist zwar sehr restriktiv, was fr die Sicherheit spricht, hat jedoch den sehr groen Nachteil, dass in der Erstellungsphase immer Verbindungen blockiert werden, die eigentlich erwnscht sind. This can be replaced by the keyword "internal" (see examples below, at the "reginfo" section). Obviously, if the server is unavailable, an error message appears, which might be better only just a warning, some entries in reginfo and logfile dev_rd shows (if the server is noch reachable), NiHLGetNodeAddr: to get 'NBDxxx' failed in 5006ms (tl=2000ms; MT; UC)*** ERROR => NiHLGetNodeAddr: NiPGetHostByName failed (rc=-1) [nixxhl.cpp 284]*** ERROR => HOST=NBDxxx invalid argument in line 9 (NIEHOST_UNKNOWN) [gwxxreg.c 2897]. While it was recommended by some resources to define a deny all rule at the end of reginfo, secinfo ACL this is not necessary. If the called program is not an RFC enabled program (compiled with the SAP RFC library) the call will time out, but the program is still left running on the OS level! This is defined by the letter, which servers are allowed to register which program aliases as a Registered external RFC Server. Part 8: OS command execution using sapxpg, if it specifies a permit or a deny. This means that the sequence of the rules is very important, especially when using general definitions. Access attempts coming from a different domain will be rejected. Spielen Sie nun die in der Queue stehenden Support Packages ein [Seite 20]. Please follow me to get a notification once i publish the next part of the series. The secinfo file is holding rules controlling which programs (based on their executable name or fullpath, if not in $PATH) can be started by which user calling from which host(s) (based on its hostname/ip-address) on which RFC Gateway server(s) (based on their hostname/ip-address). The RFC Gateway does not perform any additional security checks. There are two different syntax versions that you can use (not together). P TP=* USER=* USER-HOST=internal HOST=internal. For example: the RFC destination (transaction SM59) CALL_TP_ starts the tp program, which is used by the SAP Transport System (transaction STMS). A custom allow rule has to be maintained on the proxying RFC Gateway only. It is configured to start the tax calculation program at the CI of the SAP system, as the tax system is installed only there. With this rule applied you should properly secure access to the OS (e.g., verify if all existing OS users are indeed necessary, SSH with public key instead of user+pw). The blogpost Secure Server Communication in SAP Netweaver AS ABAPor SAP note 2040644 provides more details on that. At time of writing this can not be influenced by any profile parameter. Check out our SAST SOLUTIONS website or send us an e-mail us at sast@akquinet.de. In case the files are maintained, the value of this parameter is irrelevant; gw/sim_mode: activates/deactivates the simulation mode (see the previous section of this WIKI page). Trademark. We first registered it on the server it is defined (which was getting de-registered after a while so we registered it again through background command nohup *** & ), This solved the RFC communication on that Dialogue instance yet other Dialogue instances were not able to communicate on the RFC. For a RFC Gateway of AS Java or a stand-alone RFC Gateway this can be determined with the command-line tool gwmon by running the command gwmon nr= pf= then going to the menu by typing m and displaying the client table by typing 3. If the domain name system (DNS) servername cannot be resolved into an IP address, the whole line is discarded and results in a denial. Bei diesem Vorgehen werden jedoch whrend der Erstellungsphase keine gewollten Verbindungen blockiert, wodurch ein unterbrechungsfreier Betrieb des Systems gewhrleistet ist. With this blogpost series i try to give a comprehensive explanation of the RFC Gateway Security: Part 1: General questions about the RFC Gateway and RFC Gateway security. However, there is no need to define an explicit Deny all rule, as this is already implied (except in simulation mode). This order is not mandatory. Program hugo is allowed to be started on every local host and by every user. Part 7: Secure communication As we learned in part 2 SAP introduced the following internal rule in the in the reginfo ACL: P TP=* HOST=internal,local ACCESS=internal,local CANCEL=internal,local. 1. other servers had communication problem with that DI. So lets shine a light on security. Here, activating Gateway logging and evaluating the log file over an appropriate period (e.g. In SAP NetWeaver Application Server ABAP: Every Application Server has a built-in RFC Gateway. Da das aber gewnscht ist, mssen die Zugriffskontrolllisten schrittweise um jedes bentigte Programm erweitert werden. In other words, the SAP instance would run an operating system level command. All other programs from host 10.18.210.140 are not allowed to be registered. Hello Venkateshwar, thank you for your comment. The secinfo file has rules related to the start of programs by the local SAP instance. Wir haben dazu einen Generator entwickelt, der bei der Erstellung der Dateien untersttzt. Datenbankschicht: In der Datenbank, welche auf einem Datenbankserver liegt, werden alle Daten eines Unternehmens gesichert. Note: depending on the systems settings, it will not be the RFC Gateway itself that will start the program. From my experience the RFC Gateway security is for many SAP Administrators still a not well understood topic. To do this, in the gateway monitor (transaction SMGW) choose Goto Expert Functions External Security Reread . The default rules of reginfo and secinfo ACL (as mentioned in part 2 and part 3) are enabled if either profile parameter gw/acl_mode = 1 is set or if gw/reg_no_conn_info includes the value 16 in its bit mask, and if no custom ACLs are defined. The related program alias can be found in column TP Name: We can verify if the functionality of these Registered RFC Server programs is accessible from the AS ABAP by looking for a TCP/IP connection in transaction SM59 with Technical Settings Activation Type = Registered Server Program the corresponding Program ID and either no Gateway Options or connection details to any of the RFC Gateways belonging to the same system set: Please note: If the AS ABAP system has more than one application servers and therefore also more than one RFC Gateways there may be scenarios in which the Registered Server Program is registered at one specific RFC Gateway only. The keyword internal means all servers that are part of this SAP system (in this case, the SolMan system). Hufig ist man verpflichtet eine Migration durchzufhren. Each instance can have its own security files with its own rules. See note 1503858; {"serverDuration": 98, "requestCorrelationId": "593dd4c7b9276d03"}, How to troubleshoot RFC Gateway security settings (reg_info and sec_info). Falls Sie danach noch immer keine Anwendungen / Registerkarten sehen, liegt es daran, dass der Gruppe / dem Benutzer das allgemeine Anzeigenrecht auf der obersten Ebene der jeweiligen Registerkarte fehlt. Depending on the settings of the reginfo ACL a malicious user could also misuse this permissions to start a program which registers itself on the local RFC Gateway, e.g.,: Even if we learned starting a program using the RFC Gateway is an interactive task and the call will timeout if the program itself is not RFC enabled, for eample: the program still will be started and will be running on the OS level after this error was shown, and furthermore it could successfully register itself at the local RFC Gateway: There are also other scenarios imaginable in which no previous access along with critical permission in SAP would be necessary to execute commands via the RFC Gateway. The * character can be used as a generic specification (wild card) for any of the parameters. The wildcard * should be strongly avoided. If you set it to zero (highlynotrecommended), the rules in the reginfo/secinfo/proxy info files will still be applied. Here, activating Gateway logging and evaluating the log file over an appropriate period (e.g. While it is common and recommended by many resources to define this rule in a custom reginfo ACL as the last rule, from a security perspective it is not an optimal approach. Its functions are then used by the ABAP system on the same host. Check the secinfo and reginfo files. Um diese Website nutzen zu knnen, aktivieren Sie bitte JavaScript. Haben Support Packages in der Queue Verbindungen zu Support Packages einer anderen Komponente (weitere Vorgngerbeziehung, erforderliches CRT) wird die Queue um weitere Support Packages erweitert, bis alle Vorgngerbeziehungen erfllt sind. Wechseln Sie dazu auf die gewnschte Registerkarte (im Beispiel ist das Universen), whlen Sie Verwalten --> Sicherheit auf oberster Ebene --> Alle Universen (je nach Registerkarte unterscheidet sich der letzte Punkt). The related program alias also known as TP Name is used to register a program at the RFC Gateway. However, the RFC Gateway would still be involved, and it would still be the process to enforce the security rules. Please note: One should be aware that starting a program using the RFC Gateway is an interactive task. Its location is defined by parameter gw/sec_info. This page contains information about the RFC Gateway ACLs (reginfo and secinfo files), the Simulation Mode, as well as the workflow showing how the RFC Gateway works with regards to the ACLs versus the Simulation Mode. That part is talking about securing the connection to the Message Server, which will prevent tampering with they keyword "internal", which can be used on the RFC Gateway security ACL files. Part 2: reginfo ACL in detail. It is strongly recommended to use syntax of Version 2, indicated by #VERSION=2in the first line of the files. An example could be the integration of a TAX software. To control the cancellation of registered programs, a cancel list can be defined for each entry (same as for the ACCESS list). Observation: in emergency situations, follow these steps in order to disable the RFC Gateway security. SMGW-->Goto -->External Functions --> External Security --> Maintenance of ACL files --> pop-up is shown as below: "Gateway content and file content for reginfo do not match starting with index " (xx is the index value shown in the pop-up), Gateway, Security, length, line, rule, limit, abap , KBA , BC-CST-GW , Gateway/CPIC , Problem. secinfo: P TP=* USER=* USER-HOST=* HOST=*. Da das aber gewnscht ist, mssen die Zugriffskontrolllisten schrittweise um jedes bentigte Programm erweitert werden. Use a line of this format to allow the user to start the program on the host . Somit knnen keine externe Programme genutzt werden. Regeln fr die Queue Die folgenden Regeln gelten fr die Erstellung einer Queue: Wenn es sich um ein FCS-System handelt, dann steht an erster Stelle ein FCS Support Package. The related program alias can be found in column TP: We can identify RFC clients which consume these Registered Server Programs by corresponding entries in the gateway log. From a technical perspective the RFC Gateway is a SAP kernel process (gwrd, gwrd.exe) running on OS level as user adm. As soon as a program has registered in the gateway, the attributes of the retrieved entry (specifically ACCESS) are passed on to the registered program. We can look for programs listed with Type = REGISTER_TP and field ADDR set to any IP address or hostname not belonging to any application server of the same system. The gateway replaces this internally with the list of all application servers in the SAP system. Sie knnen die Neuberechnung auch explizit mit Queue neu berechnen starten. The wild card character * stands for any number of characters; the entry * therefore means no limitation, fo* stands for all names beginning with fo; foo stands precisely for the name foo. (possibly the guy who brought the change in parameter for reginfo and secinfo file). BC-CST-GW , Gateway/CPIC , BC-NET , Network Infrastructure , Problem . Wir untersttzen Sie gerne bei Ihrer Entscheidungen. Part 2: reginfo ACL in detail. Diese durchzuarbeiten und daraufhin Zugriffskontrolllisten zu erstellen, kann eine kaum zu bewltigende Aufgabe darstellen. Part 8: OS command execution using sapxpg. The first letter of the rule can be either P (for Permit) or D (for Deny). In the gateway monitor (SMGW) choose Goto Logged On Clients , use the cursor to select the registered program, and choose Goto Logged On Clients Delete Client . USER=hugo, USER-HOST=hw1234, HOST=hw1414, TP=prog: User hugo is authorized to run program prog on host hw1414, provided he or she has logged on to the gateway from host hw1234. Sie knnen die Queue-Auswahl reduzieren. This could be defined in. If the Gateway protections fall short, hacking it becomes childs play. Someone played in between on reginfo file. Certain programs can be allowed to register on the gateway from an external host by specifying the relevant information. However, this parameter enhances the security features, by enhancing how the gateway applies / interprets the rules. You have configured the SLD at the Java-stack of the SolMan system, using the RFC Gateway of the SolMans ABAP-stack. Successful and rejected registrations, and calls from registered programs can be ascertained using Gateway Logging with indicator S. Any error lines are put in the trace file dev_rd, and are not read in. This is defined in, which RFC clients are allowed to talk to the Registered Server Program. 3. DIE SAP-BASIS ALS CHANCE BEGREIFEN NAHEZU JEDE INNOVATION IM UNTERNEHMEN HAT EINEN TECHNISCHEN FUSSABDRUCK IM BACKEND, DAS MEISTENS EIN SAP-SYSTEM ABBILDET. Visit SAP Support Portal's SAP Notes and KBA Search. The solution is to stop the SLD program, and start it again (in other words, de-register the program, and re-register it). A Stand-alone Gateway could utilise this keyword only after it was attached to the Message Server of AS ABAP and the profile parameter gw/activate_keyword_internal was set. Part 3: secinfo ACL in detail. For example: an SAP SLD system registering the SLD_UC and SLD_NUC programs at an ABAP system. A LINE with a HOST entry having multiple host names (e.g. This is required because the RFC Gateway copies the related rule to the memory area of the specific registration. The secinfo security file is used to prevent unauthorized launching of external programs. Support Packages fr eine ausgewhlte Komponente werden entsprechend ihrer Reihenfolge in die Queue gestellt. Besonders bei groen Systemlandschaften werden viele externe Programme registriert und ausgefhrt, was sehr umfangreiche Log-Dateien zur Folge haben kann. SMGW-->Goto -->External Functions --> External Security --> Maintenance of ACL files --> pop-up is shown as below: "Gateway content and file content for reginfo do not match starting with index <xx>" (xx is the index value shown in the . The Solution Manager (SolMan) system has only one instance, running at the host sapsmci. This is a list of host names that must comply with the rules above. This is an allow all rule. Program foo is only allowed to be used by hosts from domain *.sap.com. IP Addresses (HOST=, ACCESS= and/or CANCEL=): You can use IP addresses instead of host names. For example: you have changed to the rule related to the SLD_UC program, allowing a new server to communicate with it (you added the new server to the ACCESS option). The default configuration of an ASCS has no Gateway. There are other SAP notes that help to understand the syntax (refer to the Related notes section below). The secinfosecurity file is used to prevent unauthorized launching of external programs. See the examples in the note1592493; 2)It is possible to change the rules in the files and reload its configuration without restart the RFC Gateway: open the transaction SMGW -> Goto -> expert functions -> external security -> reload However, in such situation, it is mandatory to de-register the registered program involved and reregister it again because programs already registered will continue following the old rules; 3)The rules in the secinfo and reginfo file do not always use the same syntax, it depends of the VERSION defined in the file. Hint: Besides the syntax check, it also provides a feature supporting rule creation by predicting rules out of an automated gateway log analysis. Please make sure you have read part 1 4 of this series. ber das Dropdown-Men regeln Sie, ob und wie weit Benutzer der Gruppe, die Sie aktuell bearbeiten, selbst CMC-Registerkartenkonfigurationen an anderen Gruppen / Benutzern vornehmen knnen! E.g "RegInfo" file entry, P TP=BIPREC* USER=* HOST=* NO=1 CANCEL=* ACCESS=* A combination of these mitigations should be considered in general. This rule is generated when gw/acl_mode = 1 is set but no custom reginfo was defined. Another mitigation would be to switch the internal server communication to TLS using a so-called systemPKI by setting the profile parameter system/secure_communication = ON. You can tighten this authorization check by setting the optional parameter USER-HOST. Es gibt folgende Grnde, die zum Abbruch dieses Schrittes fhren knnen: CANNOT_SKIP_ATTRIBUTE_RECORD: Die Attribute knnen in der OCS-Datei nicht gelesen werden. If the option is missing, this is equivalent to HOST=*. RFC had issue in getting registered on DI. Additional ACLs are discussed at this WIKI page. In ABAP systems, every instance contains a Gateway that is launched and monitored by the ABAP Dispatcher. Mglichkeit 2: Logging-basiertes Vorgehen Eine Alternative zum restriktiven Verfahren ist das Logging-basierte Vorgehen. For example: The SAP KBAs1850230and2075799might be helpful. Whrend der Freischaltung aller Verbindungen wird mit dem Gateway-Logging eine Aufzeichnung aller externen Programmaufrufe und Systemregistrierungen vorgenommen. Part 4: prxyinfo ACL in detail In other words the same host running the ABAP system is also running the SAP IGS, for example the integrated IGS (as part of SAP NW AS ABAP) may be started on the application servers host during the start procedure of the ABAP system. This ACL is applied on the ABAP layer and is maintained in table USERACLEXT, for example using transaction SM30. Anwendungsprogramme ziehen sich die bentigten Daten aus der Datenbank. gw/acl_mode: this parameter controls the value of the default internal rules that the RFC Gateway will use, in case the reginfo/secinfo file is not maintained. where ist the hint or wiki to configure a well runing gw-security ? Part 6: RFC Gateway Logging. Part 7: Secure communication TP=Foo NO=1, that is, only one program with the name foo is allowed to register, all further attempts to register a program with this name are rejected. If no access list is specified, the program can be used from any client. If the Gateway Options are not specified the AS will try to connect to the RFC Gateway running on the same host. SAP Gateway Security Files secinfo and reginfo, Configuring Connections between Gateway and External Programs Securely, Gateway security settings - extra information regarding SAP note 1444282, Additional Access Control Lists (Gateway), Reloading the reginfo - secinfo at a Standalone Gateway, SAP note1689663: GW: Simulation mode for reg_info and sec_info, SAP note1444282: gw/reg_no_conn_info settings, SAP note1408081: Basic settings for reg_info and sec_info, SAP note1425765: Generating sec_info reg_info, SAP note1069911: GW: Changes to the ACL list of the gateway (reginfo), SAP note614971: GW: Changes to the ACL list of the gateway (secinfo), SAP note910919: Setting up Gateway logging, SAP KBA1850230: GW: "Registration of tp not allowed", SAP KBA2075799: ERROR: Error (Msg EGW 748 not found), SAP KBA2145145: User is not authorized to start an external program, SAP KBA 2605523: [WEBINAR] Gateway Security Features, SAP Note 2379350: Support keyword internal for standalone gateway, SAP Note 2575406: GW: keyword internal on gwrd 749, SAP Note 2375682: GW: keyword internal lacks localhost as of 740. ooohhh my god, (It could not have been more complicated -obviously the sequence of lines is important): "# This must always be the last rule on the file see SAP note 1408081" + next line content, is not included as comment within the default-delivered reginfo file or secinfo file (after installation) -, this would save a lot ofwasted life time, gw/acl_mode: ( looks like to enable/disable the complete gw-security config, but ). In the previous parts we had a look at the different ACLs and the scenarios in which they are applied. The location of the reginfo ACL file is specified by the profile parameter gw/reg_info. How to guard your SAP Gateway against unauthorized calls, Study shows SAP systems especially prone to insider attacks, Visit our Pathlock Germany website https://pathlock.com/de/, Visit our Pathlock Blog: https://pathlock.com/de/blog/, SAST SOLUTIONS: Now member of Pathlock Group. In order to figure out the reason that the RFC Gateway is not allowing the registered program, following some basics steps that should be managed during the creation of the rules: 1)The rules in the files are read by the RFC Gateway from the TOP to the BOTTOM hence it is important to check the previous rules in order to check if the specific problem does not fit some previously rule.
