SAP NetWeaver AS ABAP vulnerabilities

SAP NetWeaver AS ABAP and ABAP Platform do not sufficiently verify incoming authentication assertions under certain configurations. An unauthenticated attacker could submit crafted data to bypass authentication and impersonate arbitrary users, including privileged accounts.

Due to the memory corruption vulnerability in SAP NetWeaver AS ABAP and ABAP Platform, an unauthenticated attacker can send a corrupted SAP Logon Ticket or SAP Assertion Ticket to the SAP application server. This leads to a dereference of NULL which makes the work process crash. As a result, it has a low impact on the availability but no impact on the confidentiality and integrity.

SAP NetWeaver AS ABAP (BSP Framework) versions 700–757 do not sufficiently sanitize input, allowing an unauthenticated user to alter the current user session by injecting malicious code over the network and gain access to unintended data. This may have a limited impact on confidentiality and integrity.
