SAP NetWeaver Application Server (ABAP) - versions KERNEL 7.53, KERNEL 7.54, KERNEL 7.77, KERNEL 7.85, KERNEL 7.89, KERNEL 7.93, KERNEL 7.94, KRNL64UC 7.53, under certain conditions, allows an attacker to access information which could otherwise be restricted with low impact on confidentiality of the application.

Under certain condition SAP NetWeaver Application Server ABAP - versions KERNEL 722, KERNEL 7.53, KERNEL 7.77, KERNEL 7.85, KERNEL 7.89, KERNEL 7.54, KERNEL 7.91, KERNEL 7.92, KERNEL 7.93, KERNEL 7.94, KERNEL64UC 7.22, KERNEL64UC 7.22EXT, KERNEL64UC 7.53, KERNEL64NUC 7.22, KERNEL64NUC 7.22EXT, allows an unauthenticated attacker to access the unintended data due to the lack of restrictions applied which may lead to low impact in confidentiality and no impact on the integrity and availability of the application.

SAP CommonCryptoLib does not perform necessary authentication checks, which may result in missing or wrong authorization checks for an authenticated user, resulting in escalation of privileges. Depending on the application and the level of privileges acquired, an attacker could abuse functionality restricted to a particular user group as well as read, modify or delete restricted data.

SAP CommonCryptoLib allows an unauthenticated attacker to craft a request, which when submitted to an open port causes a memory corruption error in a library which in turn causes the target component to crash making it unavailable. There is no ability to view or modify any information.

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.

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 NetWeaver Application Server ABAP (Applications based on SAP GUI for HTML), versions - KRNL64NUC - 7.49, KRNL64UC - 7.49,7.53, KERNEL - 7.49,7.53,7.77,7.81,7.84, does not sufficiently encode user-controlled inputs, resulting in Cross-Site Scripting (XSS) vulnerability.

SAP NetWeaver AS ABAP, versions - KRNL32NUC - 7.22,7.22EXT, KRNL32UC - 7.22,7.22EXT, KRNL64NUC - 7.22,7.22EXT,7.49, KRNL64UC - 8.04,7.22,7.22EXT,7.49,7.53,7.73, KERNEL - 7.22,8.04,7.49,7.53,7.73,7.77,7.81,7.82,7.83,7.84, allows an unauthorized attacker to insert cleartext commands due to improper restriction of I/O buffering into encrypted SMTP sessions over the network which can partially impact the integrity of the application.
