SAP : Security Vulnerabilities, CVEs, (Gain Privilege)

SAP S/4HANA Finance for (Advanced Payment Management) - versions SAPSCORE 128, S4CORE 107, does not perform necessary authorization checks. A function import could be triggered allowing the attacker to create in-house bank accounts leading to low impact on the confidentiality of the application.

In SAP Commerce Cloud - versions HY_COM 1905, HY_COM 2005, HY_COM2105, HY_COM 2011, HY_COM 2205, COM_CLOUD 2211, a locked B2B user can misuse the forgotten password functionality to un-block his user account again and re-gain access if SAP Commerce Cloud - Composable Storefront is used as storefront, due to weak access controls in place. This leads to a considerable impact on confidentiality and integrity.

The ACL (Access Control List) of SAP Message Server - versions KERNEL 7.22, KERNEL 7.53, KERNEL 7.54, KERNEL 7.77, RNL64UC 7.22, RNL64UC 7.22EXT, RNL64UC 7.53, KRNL64NUC 7.22, KRNL64NUC 7.22EXT, can be bypassed in certain conditions, which may enable an authenticated malicious user to enter the network of the SAP systems served by the attacked SAP Message server. This may lead to unauthorized read and write of data as well as rendering the system unavailable.

SAP PowerDesigner - version 16.7, has improper access control which might allow an unauthenticated attacker to run arbitrary queries against the back-end database via Proxy.

Due to missing authentication check in SAP Host Agent - version 7.22, an unauthenticated attacker can set an undocumented parameter to a particular compatibility value and in turn call read functions. This allows the attacker to gather some non-sensitive information about the server.  There is no impact on integrity or availability.

SAP NetWeaver Application Server ABAP and ABAP Platform - version KRNL64NUC, 7.22, KRNL64NUC 7.22EXT, KRNL64UC 7.22, KRNL64UC 7.22EXT, KRNL64UC 7.53, KERNEL 7.22, KERNEL, 7.53, KERNEL 7.77, KERNEL 7.81, KERNEL 7.85, KERNEL 7.89, KERNEL 7.54, KERNEL 7.92, KERNEL 7.93, under some conditions, performs improper authentication checks for functionalities that require user identity. An attacker can perform malicious actions over the network, extending the scope of impact, causing a limited impact on confidentiality, integrity and availability.

When creating a journal entry template in SAP S/4HANA (Manage Journal Entry Template) - versions S4CORE 104, 105, 106, 107, an attacker could intercept the save request and change the template, leading to an impact on confidentiality and integrity of the resource. Furthermore, a standard template could be deleted, hence making the resource temporarily unavailable.

SAP Business One installation - version 10.0, does not perform proper authentication and authorization checks for SMB shared folder. As a result, any malicious user can read and write to the SMB shared folder. Additionally, the files in the folder can be executed or be used by the installation process leading to considerable impact on confidentiality, integrity and availability.

A Windows user with basic user authorization can exploit a DLL hijacking attack in SapSetup (Software Installation Program) - version 9.0, resulting in a privilege escalation running code as administrator of the very same Windows PC. A successful attack depends on various preconditions beyond the attackers control.

SAP NetWeaver AS Java (Object Analyzing Service) - version 7.50, does not perform necessary authorization checks, allowing an unauthenticated attacker to attach to an open interface and make use of an open naming and directory API to access a service which will enable them to access but not modify server settings and data with no effect on availability., resulting in escalation of privileges.

Cache Management Service in SAP NetWeaver Application Server for Java - version 7.50, does not perform any authentication checks for functionalities that require user identity

Due to missing authentication check, SAP NetWeaver AS for Java - version 7.50, allows an unauthenticated attacker to attach to an open interface and make use of an open naming and directory API to access services which can be used to perform unauthorized operations affecting users and services across systems. On a successful exploitation, the attacker can read and modify some sensitive information but can also be used to lock up any element or operation of the system making that it unresponsive or unavailable.

An unauthenticated attacker in SAP NetWeaver AS for Java - version 7.50, due to improper access control, can attach to an open interface and make use of an open naming and directory API to access services which can be used to perform unauthorized operations affecting users and data on the current system. This could allow the attacker to have full read access to user data, make modifications to user data, and make services within the system unavailable.

In SAP Host Agent (Windows) - versions 7.21, 7.22, an attacker who gains local membership to SAP_LocalAdmin could be able to replace executables with a malicious file that will be started under a privileged account. Note that by default all user members of SAP_LocaAdmin are denied the ability to logon locally by security policy so that this can only occur if the system has already been compromised.

SAP Solution Manager (Diagnostic Agent) - version 7.20, allows an authenticated attacker on Windows system to access a file containing sensitive data which can be used to access a configuration file which contains credentials to access other system files. Successful exploitation can make the attacker access files and systems for which he/she is not authorized.

SAP GRC Access control Emergency Access Management allows an authenticated attacker to access a Firefighter session even after it is closed in Firefighter Logon Pad. This attack can be launched only within the firewall. On successful exploitation the attacker can gain access to admin session and completely compromise the application.

SAP startservice - of SAP NetWeaver Application Server ABAP, Application Server Java, ABAP Platform and HANA Database - versions KERNEL 7.22, 7.49, 7.53, 7.77, 7.81, 7.85, 7.86, 7.87, 7.88, KRNL64NUC 7.22, 7.22EXT, 7.49, KRNL64UC 7.22, 7.22EXT, 7.49, 7.53, SAPHOSTAGENT 7.22, - on Unix systems, s-bit helper program sapuxuserchk, can be abused physically resulting in a privilege escalation of an attacker leading to low impact on confidentiality and integrity, but a profound impact on availability.

SAP Adaptive Server Enterprise (ASE) - version 16.0, installation makes an entry in the system PATH environment variable in Windows platform which, under certain conditions, allows a Standard User to execute malicious Windows binaries which may lead to privilege escalation on the local system. The issue is with the ASE installer and does not impact other ASE binaries.

SAP Business One, version - 10.0, allows a local attacker with access to the victim's browser under certain circumstances, to login as the victim without knowing his/her password. The attacker could so obtain highly sensitive information which the attacker could use to take substantial control of the vulnerable application.

SAP NetWeaver ABAP Server and ABAP Platform, versions - 700, 701, 702, 731, 740, 750, 751, 752, 753, 754, 755, 804, does not create information about internal and external RFC user in consistent and distinguished format, which could lead to improper authentication and may be exploited by malicious users to obtain illegitimate access to the system.

An unquoted service path in SAPSetup, version - 9.0, could lead to privilege escalation during the installation process that is performed when an executable file is registered. This could further lead to complete compromise of confidentiality, Integrity and Availability.

SAP NetWeaver AS JAVA (Customer Usage Provisioning Servlet), versions - 7.31, 7.40, 7.50, allows an attacker to read some statistical data like product version, traffic, timestamp etc. because of missing authorization check in the servlet.

SAP MII allows users to create dashboards and save them as JSP through the SSCE (Self Service Composition Environment). An attacker can intercept a request to the server, inject malicious JSP code in the request and forward to server. When this dashboard is opened by users having at least SAP_XMII Developer role, malicious content in the dashboard gets executed, leading to remote code execution in the server, which allows privilege escalation. The malicious JSP code can contain certain OS commands, through which an attacker can read sensitive files in the server, modify files or even delete contents in the server thus compromising the confidentiality, integrity and availability of the server hosting the SAP MII application. Also, an attacker authenticated as a developer can use the application to upload and execute a file which will permit them to execute operating systems commands completely compromising the server hosting the application.

SAP HANA Database, version - 2.0, does not correctly validate the username when performing SAML bearer token-based user authentication. It is possible to manipulate a valid existing SAML bearer token to authenticate as a user whose name is identical to the truncated username for whom the SAML bearer token was issued.

SAP NetWeaver AS JAVA, versions - 7.20, 7.30, 7.31, 7.40, 7.50, allows an attacker who is authenticated as an administrator to use the administrator console, to expose unauthenticated access to the file system and upload a malicious file. The attacker or another user can then use a separate mechanism to execute OS commands through the uploaded file leading to Privilege Escalation and completely compromise the confidentiality, integrity and availability of the server operating system and any application running on it.
