Title
Memory Corruption vulnerability in Application Server ABAP of SAP NetWeaver and ABAP Platform
Summary
Due to improper RFC protocol validation in the SAP Kernel used by the Application Server ABAP of SAP NetWeaver and ABAP Platform, an unauthenticated attacker can send a crafted RFC request that exploits logical errors in memory management, leading to memory corruption. This could lead to a high impact on the confidentiality, integrity, and availability of the application.
