Remote code execution via remoting path traversal
Published Dec 10, 2025 · Updated Dec 10, 2025
Path traversal in Barracuda RMM before 2025.1.1 allows remote attackers to read arbitrary files through Service Center's .NET Remoting service. An exposed remoting method accepts an attacker-controlled path without restricting traversal outside its intended directory; public records do not identify the method. No authentication or user interaction is required, and retrieving the host's .NET machine keys provides a path from file disclosure to remote code execution.

Exploitability
Present is not the same as exploitable
Compare your product and version with the public record. A matching version still requires validation against your environment.
Is a vulnerable build present?
Compare these published version ranges with your installed build and any vendor patches.
