CVE-2022-26100Network attack vector

Process crash via malformed archive parsing

Published Mar 8, 2022 · Updated Aug 3, 2024

Improper array-index validation in SAPCAR before 7.22 allows attackers to crash the process by supplying a malformed SAP archive. Archive parsing accepts invalid input and reaches an invalid memory access, but SAP has not identified the parser routine or unchecked field publicly. The archive must be processed by SAPCAR; the substantiated consequence is a process crash, while public vendor material does not substantiate broader privileged access.
