SAP NetWeaver Application Server ABAP and ABAP Platform - version KRNL64NUC, 7.22, KRNL64NUC 7.22EXT, KRNL64UC 7.22, KRNL64UC 7.22EXT, KRNL64UC 7.53, KERNEL 7.22, KERNEL, 7.53, KERNEL 7.77, KERNEL 7.81, KERNEL 7.85, KERNEL 7.89, KERNEL 7.54, KERNEL 7.92, KERNEL 7.93, under some conditions, performs improper authentication checks for functionalities that require user identity. An attacker can perform malicious actions over the network, extending the scope of impact, causing a limited impact on confidentiality, integrity and availability.

SAP NetWeaver Application Server for ABAP (Kernel) and ABAP Platform (Kernel) - versions KERNEL 7.22, 8.04, 7.49, 7.53, 7.77, 7.81, 7.85, 7.86, 7.87, KRNL64UC 8.04, 7.22, 7.22EXT, 7.49, 7.53, KRNL64NUC 7.22, 7.22EXT, 7.49, does not sufficiently validate sap-passport information, which could lead to a Denial-of-Service attack. This allows an unauthorized remote user to provoke a breakdown of the SAP Web Dispatcher or Kernel work process. The crashed process can be restarted immediately, other processes are not affected.
