Due to an uncontrolled recursion in SAP Web Dispatcher and SAP Internet Communication Manager, the application may crash, leading to denial of service, but can be restarted automatically.

In SAP NetWeaver Application Server for ABAP, from 7.0 to 7.02, 7.30, 7.31, 7.40 and from 7.50 to 7.53, applications do not sufficiently encode user-controlled inputs, resulting in Cross-Site Scripting (XSS) vulnerability.

Under certain conditions SAP Gateway of ABAP Application Server (fixed in SAPGWFND 7.5, 7.51, 7.52, 7.53; SAPBASIS 7.5) allows an attacker to access information which would otherwise be restricted.

By overlong input values an attacker may force overwrite of the internal program stack in SAP Web Dispatcher - versions 7.53, 7.77, 7.81, 7.85, 7.86, or Internet Communication Manager - versions KRNL64NUC 7.22, 7.22EXT, 7.49, KRNL64UC 7.22, 7.22EXT, 7.49, 7.53, KERNEL 7.22, 7.49, 7.53, 7.77, 7.81, 7.85, 7.86, which makes these programs unavailable, leading to denial of service.
