CVE-2025-3517Network attack vector

Privilege escalation via stale JIT account SID

Published May 1, 2025 · Updated May 2, 2025

Incorrect privilege assignment in Devolutions Server 2025.1.5.0 and earlier allows remote authenticated users to elevate a configured user. When a PAM user changes the username on a configured JIT account, the application retains the internal account's prior SID instead of replacing it. The authenticated workflow can then elevate the user identified by that stale SID, granting unintended access in the PAM context.
