Continued privileged actions via stale sessions

Published Nov 12, 2024 · Updated Nov 12, 2024

Insufficient session expiration in Siemens SINEC INS before V1.0 SP2 Update 3 allows remote authenticated users to retain access. The application leaves established sessions valid after the associated account is deleted or disabled or its permissions are changed. A previously authenticated high-privileged user can continue using the session with obsolete authority, affecting integrity without reported disclosure or interruption.
