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 place or modify files in this directory, which are executed with SYSTEM-level privileges during automation cycles. This allows attackers to gain SYSTEM-level access on affected systems. The vulnerability has a high severity with a CVSS score of 8. 5. No official patch or remediation guidance has been provided yet 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 caused by overly permissive filesystem ACLs on the C:\Windows\Automation directory. This misconfiguration allows local attackers to modify or add files that are executed under the NT AUTHORITY\SYSTEM account during routine automation cycles, resulting in SYSTEM-level privilege escalation. The vulnerability is classified under CWE-732 (Incorrect Permission Assignment for Critical Resource) and has a CVSS 4.0 score of 8.5, indicating high severity. No vendor advisory or patch information is currently available.
Potential Impact
Successful exploitation allows a local attacker with limited privileges to escalate to SYSTEM-level privileges on the affected system. This can lead to full system compromise, unauthorized access to sensitive data, and the ability to execute arbitrary code with the highest system privileges. There are no known exploits in the wild at this time.
Mitigation Recommendations
Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. Until an official fix is released, restrict local user access to the C:\Windows\Automation directory and monitor for unauthorized modifications. Avoid running Barracuda RMM versions prior to 2025.2.2 in sensitive environments if possible.
