Full details

The complete detail of the most relevant notes is as follows:

  1. Update – Security updates for the browser control Google Chromium delivered with SAP Business Client (2622660): This security note addresses multiple vulnerabilities in the 3rd party web browser control Chromium, which can be used within SAP Business Client. This note will be modified periodically based on web browser updates by the open-source project Chromium. The note priority is based on the highest CVSS score of all the vulnerabilities fixed in the latest browser release. If the SAP Business Client release is not updated to the latest patch level, displaying web pages in SAP Business Client via this open-source browser control might lead to different vulnerabilities like memory corruption, Information Disclosure and the like. The solution will be to update the SAP Business Client patch to the newest one, which contains the most current stable major release of the Chromium browser control, which passed the SAP internal quality measurements of SAP Business Client. The note has been re-released with updated ‘Solution’ and ‘Support Packages & Patches’ information CVSS v3 Base Score: 10 / 10 (Multiple CVE´s).
  2. Multiple vulnerabilities in SAP Diagnostics Agent (OSCommand Bridge and EventLogServiceCollector)( 3305369): This note lists 2 vulnerabilities in SAP Diagnosis Agent both derived from Unauthenticated RCE, one related to EventLogServiceCollector which allows an attacker to execute malicious scripts on all connected Diagnosis Agents running on Windows and the other due to lack of authentication and insufficient input validation, the OSCommand bridge allows to execute malicious scripts on all connected Diagnosis Agents running on all operating systems, both vulnerabilities compromise the confidentiality, integrity and availability of the system. CVSS v3 Base Score: 10 / 10 [CVE-2023-27497].
  3. Update – Improper access control in SAP NetWeaver AS Java (User Defined Search) (3273480): An unauthenticated attacker over the network can attach to an open interface exposed through JNDI by the User Defined Search (UDS) of SAP NetWeaver Process Integration (PI) 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 across the entire system. This allows the attacker to have full read access for user data, to make limited modifications to user data and to degrade performance of the system, leading to high impact on confidentiality and limited impact on availability and integrity of the application. The note has been re-released to provide the fix to SP026 for version 7.50. CVSS v3 Base Score: 9,9 / 10 [CVE-2022-41272].

  5. Update – Directory Traversal vulnerability in SAP NetWeaver AS for ABAP and ABAP Platform (3294595): SAP NetWeaver Application Server for ABAP and ABAP Platform allows an attacker with non-administrative authorizations to exploit a directory traversal flaw in an available service to overwrite the system files.  In this attack, no data can be read but potentially critical OS files can be overwritten making the system unavailable. In addition to the solution provided by the patch upload the note contains a workaround. This note has been re-released with updated ‘Solution’ information.
