CVE-2025-34393 is a critical-severity vulnerability rated 10/10 on the CVSS scale. Barracuda Service Center, as implemented in the RMM solution, in versions prior to 2025.1.1, does not correctly verify the name of an attacker-controlled WSDL service, leading to insecure reflection. This can result in remote code execution through either invocation of arbitrary methods or deserialization of untrusted types.. EPSS estimates a 0.59% chance of exploitation in the next 30 days.
