SAP Security Notes, January 2022

Multiple Hot News notes were released in January as part of SAP’s continued efforts to patch solutions impacted by the critical Log4Shell vulnerability. This includes Process Orchestration (note 3130521), Data Intelligence (3130920) and Business One (3131740). The central note 3131047 consolidates patches for the remote code execution vulnerability in the vulnerable Apache Log4j 2 component.

Note 3112928 deals with reflected cross-site scripting and code injection vulnerabilities in S/4HANA. The solution implements checks for malicious file uploads or downloads using the SAP Virus Scan Interface (VSI). VSI provides an interface for third party anti-virus software to protect against the import of malicious code into SAP systems.

Note 3123196 was updated for a high priority OS code injection vulnerability in specific methods of a utility class in SAP NetWeaver Application Server ABAP. Malicious code can be injected using transaction SE24 (Class Builder) or SE80 (Object Navigator). Exploitation of the vulnerability requires permissions for authorization object S_DEVELOP with values CLAS and 16 for fields OBJTYPE and ACTVT, respectively. Therefore, restricting access to these permissions also mitigates the vulnerability.
