Unauthenticated code execution via unsafe WSDL reflection
Published Dec 10, 2025 · Updated Dec 10, 2025
Unsafe reflection in Barracuda RMM Service Center before 2025.1.1 allows remote attackers to execute code through a crafted WSDL service. Service Center accepts an attacker-controlled WSDL service name without correctly verifying it, then uses that value to invoke arbitrary methods or deserialize untrusted types. No authentication or user interaction is required, and successful exploitation runs attacker-controlled code in the Service Center environment.

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.
