CVE-2026-22676: CWE-732 Incorrect Permission Assignment for Critical Resource in Barracuda Networks RMM
Barracuda Networks RMM versions prior to 2025. 2. 2 have a privilege escalation vulnerability due to incorrect permission assignment on the C:\Windows\Automation directory. Local attackers with limited privileges can exploit overly permissive filesystem ACLs to place or modify files in this directory. These files are executed under the SYSTEM account during routine automation cycles, allowing attackers to gain SYSTEM-level privileges. The vulnerability has a high severity score of 8. 5. No official patch or remediation guidance is currently provided by the vendor. There are no known exploits in the wild at this time.
AI Analysis
Technical Summary
CVE-2026-22676 is a privilege escalation vulnerability in Barracuda Networks RMM prior to version 2025.2.2. It arises from overly permissive access control lists on the C:\Windows\Automation directory, which allows local attackers to modify or add files that are executed with SYSTEM privileges during automation tasks. This improper permission assignment corresponds to CWE-732. The vulnerability enables attackers with local access to escalate their privileges to SYSTEM level without user interaction. The CVSS 4.0 base score is 8.5, reflecting high impact and exploitability with low attack complexity and no required user interaction.
Potential Impact
Successful exploitation allows a local attacker with limited privileges to gain SYSTEM-level privileges on the affected system. This can lead to full control over the system, including the ability to execute arbitrary code with the highest privileges. The vulnerability impacts confidentiality, integrity, and availability as indicated by the CVSS vector. There are no reports of active exploitation in the wild.
Mitigation Recommendations
Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. Until an official fix is available, organizations should restrict local access to affected systems and review filesystem permissions on the C:\Windows\Automation directory to ensure they are not overly permissive. Monitor for unauthorized modifications to automation content. Avoid relying solely on this directory for critical automation tasks if possible.
