SAP NetWeaver Application Server ABAP vulnerability analysis and mitigation

CVE-2025-0070 is a critical vulnerability affecting SAP NetWeaver Application Server for ABAP and ABAP Platform, discovered and disclosed in January 2025. The vulnerability allows an authenticated attacker to obtain illegitimate access to the system by exploiting improper authentication checks. This vulnerability has been assigned a CVSS score of 9.9, indicating its critical severity (SecurityOnline, SecurityWeek).

The vulnerability stems from improper authentication checks in the system.
