Description

Memory Corruption Vulnerability in SAP NetWeaver AS ABAP (Internet Communication Manager)

SAP NetWeaver Application Server ABAP does not sufficiently validate certain network input processed by an internal component. An unauthenticated attacker could send specially crafted network traffic to trigger a memory corruption condition in the affected functionality. Successful exploitation could allow the attacker to execute arbitrary code and fully compromise the system, resulting in a high impact on confidentiality, integrity and availability of the system.
