Technical details

An OS command injection vulnerability (CWE-77) exists in SAP NetWeaver Application Server for ABAP and ABAP Platform. The flaw allows an authenticated attacker with high privileges (administrative access) to execute specially crafted shell commands on the underlying server via the network. A significant aspect of this vulnerability is the ability to bypass the system's logging mechanism, allowing for undetected execution of unintended commands. This can lead to a complete loss of integrity and availability for the affected application. SAP has released security notes (e.g., 3730019) to address this issue.
