CVE-2023-35874Network attack vector

Authenticated cross-scope actions via incorrect RFC parameter evaluation

Published Jul 11, 2023 · Updated Oct 23, 2024

Improper authentication in SAP NetWeaver AS ABAP and ABAP Platform kernels allows remote authenticated users to perform malicious actions. The BC-MID-RFC kernel code incorrectly evaluates the no value of rfc/allowoldticket4tt, allowing identity-dependent functionality to proceed without the intended check. Exploitation requires authenticated network access and specific conditions; successful abuse causes limited data exposure, modification, and service interruption.
