CVE-2025-34153

Summary

Hyland OnBase versions prior to 17.0.2.87 (other versions may be affected) are vulnerable to unauthenticated remote code execution via insecure deserialization on the .NET Remoting TCP channel. The service registers a listener on port 6031 with the URI endpoint TimerServer, implemented in Hyland.Core.Timers.dll. This endpoint deserializes untrusted input using the .NET BinaryFormatter, allowing attackers to execute arbitrary code under the context of NT AUTHORITY\SYSTEM.

Workarounds

It is recommended that customers immediately convert to the in-servicing module, Unity Scheduler. Starting with OnBase 16, Unity Scheduler is the recommended replacement. It is recommended customers using versions prior to 16 upgrade to an in-servicing release of OnBase and leverage Unity Scheduler.
