CVE-2025-34392: CWE-36 Absolute Path Traversal in Barracuda Networks RMM
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.
AI Analysis
Technical Summary
This vulnerability (CVE-2025-34392) affects Barracuda Networks RMM versions before 2025.1.1. The issue is due to insufficient validation of URLs in WSDL files controlled by an attacker, which the application later loads. Exploiting this can enable an attacker to write files arbitrarily on the system and execute remote code by uploading a webshell. The CVSS 4.0 base score is 10.0, indicating a critical severity with network attack vector, no privileges required, no user interaction, and high impact on confidentiality, integrity, availability, and scope.
Potential Impact
Successful exploitation can lead to arbitrary file writes and remote code execution on the affected system, compromising confidentiality, integrity, and availability of the system. This can allow attackers to fully control the affected RMM instance.
Mitigation Recommendations
No official patch or fix is currently available as per the provided data. Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. Until a fix is released, restrict access to the Barracuda Service Center component and monitor for suspicious activity related to WSDL processing.
