Continued account access via unrevoked sessions
Published Jan 2, 2025 · Updated Jan 2, 2025
Insufficient session expiration in Acronis Cyber Protect 16 before build 39169 allows remote authenticated users to retain access after deletion. The user-deletion path leaves existing authenticated sessions valid instead of revoking them when the associated account is removed. On Windows, exploitation requires an adjacent-network position and a previously authenticated high-privilege session, enabling continued data access and modification.
