CVE-2025-34153 is a critical unauthenticated remote code execution vulnerability affecting Hyland OnBase versions prior to 17.0.2.87. It stems from insecure deserialization on the .NET Remoting TCP channel, specifically through the TimerServer endpoint on port 6031, which uses the vulnerable .NET BinaryFormatter. This allows attackers to execute arbitrary code with NT AUTHORITY\SYSTEM privileges, posing a severe risk to affected systems. The vulnerability has a CVSS score of 10.0, indicating maximum severity and ease of exploitation with no user interaction required. While no public exploit code or active exploitation has been observed, and community discussion is minimal, its critical nature warrants immediate attention and patching.
