Elevated risk52th percentile - higher than 52% of all known CVEs
Summary
Barracuda Service Center, as implemented in the RMM solution, in versions prior to 2025.1.1, exposes a .NET Remoting service that is insufficiently protected against deserialization of arbitrary types. This can lead to remote code execution.
Risk Assessment
Risk of remote code execution and full compromise of the RMM environment and its data.
Recommendation
Update Barracuda Service Center to version 2025.1.1 or later. Restrict access to the .NET Remoting service to trusted hosts only.
Other vulnerabilities in Barracuda Service Center
See all- CVE-2025-34393Critical
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.
- CVE-2025-34392Critical
Barracuda Service Center in the RMM solution before version 2025.1.1 does not verify the URL in an attacker-controlled WSDL file that is later loaded by the application. This can lead to arbitrary file write and remote code execution via webshell upload.
- CVE-2025-34395High
Barracuda Service Center in the RMM solution, in versions prior to 2025.1.1, exposes a .NET Remoting service where an unauthenticated attacker can invoke a method vulnerable to path traversal to read arbitrary files. This vulnerability can be escalated to remote code execution by retrieving the .NET machine keys.
