Memory Corruption vulnerability in SAP NetWeaver and SAP Web Dispatcher (Internet Communication Manager)

Assigner: sap
Reserved: 29.06.2026 Published: 13.10.2026 Updated: 13.10.2026

SAP NetWeaver and SAP Web Dispatcher do not properly validate certain fields in specially crafted requests handled by an internal protocol component. An unauthenticated attacker could send a malicious request that triggers a memory-handling error, causing the affected process to crash. Successful exploitation can therefore result in a high impact on the availability of the affected application. There is no impact on the confidentiality or integrity of the application.
