An attacker with no prior authentication could craft and send malicious script to SAP GUI for HTML within Fiori Launchpad, resulting in reflected cross-site scripting attack. This could lead to stealing session information and impersonating the affected user.

SAP GUI for HTML - versions KERNEL 7.22, 7.53, 7.54, 7.77, 7.81, 7.85, 7.89, 7.91, KRNL64UC, 7.22, 7.22EXT, KRNL64UC 7.22, 7.22EXT does not sufficiently encode user-controlled inputs, resulting in a reflected Cross-Site Scripting (XSS) vulnerability. An attacker could craft a malicious URL and lure the victim to click, the script supplied by the attacker will execute in the victim user's browser. The information from the victim's web browser can either be modified or read and sent to the attacker.

SAP NetWeaver AS ABAP and ABAP Platform, versions - KRNL32NUC 7.21, 7.21EXT, 7.22, 7.22EXT, KRNL32UC 7.21, 7.21EXT, 7.22, 7.22EXT, KRNL64NUC 7.21, 7.21EXT, 7.22, 7.22EXT, 7.49, KRNL64UC 8.04, 7.21, 7.21EXT, 7.22, 7.22EXT, 7.49, 7.53, KERNEL 8.04, 7.21, 7.21EXT, 7.22, 7.22EXT, 7.49, 7.53, 7.77, 7.81, 7.84, allows an attacker to send overlong content in the RFC request type thereby crashing the corresponding work process because of memory corruption vulnerability. The work process will attempt to restart itself after the crash and hence the impact on the availability is low.
