Vulnerabilities: April 2023 Highlights
[CVE-2023-27497] Multiple vulnerabilities in SAP Diagnostics Agent (OSCommand Bridge and EventLogServiceCollector) (SAP Note 3305369)
Due to missing authentication in the EventLogServiceCollector and OSCommand Bridge components of the SAP Diagnostics Agent an attacker is able to execute malicious scripts on all connected Diagnostics Agents running on Windows. This can compromise the confidentiality, integrity, and availability of the system.
[CVE-2023-28765] Information Disclosure vulnerability in SAP BusinessObjects Business Intelligence Platform (Promotion Management) (SAP Note 3298961)
An attacker with basic privileges can get access to icmbiar file and further decrypt the file. After this attacker can gain access to BI user’s passwords and depending on the privileges of the BI user, the attacker can perform operations that can completely compromise the application.
[CVE-2023-29186] Directory Traversal vulnerability in SAP NetWeaver (BI CONT ADD ON) (SAP Note 3305907)
An attacker can exploit a Directory Traversal vulnerability in a report to upload and overwrite files on the SAP server. Data cannot be read but if a remote attacker has sufficient (administrative) privileges then potentially critical OS files can be overwritten making the system unavailable.
