- Severity: CVSS 10.0 (Critical), CNA
- Vector: CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:H/VI:H/VA:H/SC:H/SI:H/SA:H
- CISA SSVC: exploitation=poc, automatable=yes, technicalImpact=total

## Affected

- Barracuda Networks RMM: from 2025.1, fixed in 2025.1.1

## Description

Barracuda Service Center, as implemented in the RMM solution, in versions prior to 2025.1.1, does not verify the URL defined in an attacker-controlled WSDL that is later loaded by the application. This can lead to arbitrary file write and remote code execution via webshell upload.

## What to do
