Authenticated code execution via unsafe MSMQ deserialization
Published Nov 12, 2024 · Updated Oct 21, 2025
Deserialization in affected Citrix Session Recording releases allows remote authenticated users to execute code as NetworkService over an intranet. The SsRecStorageManager service reads messages from a permissively accessible MSMQ queue and applies BinaryMessageFormatter to attacker-controlled serialized objects. Access requires an authenticated account on the server's intranet, and execution is bounded to the Windows NetworkService account.
