UTMStack versions before 11.2.16 have a missing authorization vulnerability in the UTMIncidentCommandWebsocket.processCommand() handler. This handler, mapped to the /command/{hostname} STOMP destination, does not enforce role checks or command allowlists before forwarding commands. As a result, any authenticated user can execute arbitrary operating-system commands on monitored endpoints where agents typically run with high privileges.
AI Analysis
Technical Summary
The vulnerability in UTMStack prior to version 11.2.16 is due to a missing authorization check in the processCommand() method of UTMIncidentCommandWebsocket. This method handles commands sent to the /command/{hostname} STOMP destination but fails to verify user roles or restrict commands before forwarding them over gRPC to connected agents. Since these agents often run with root or SYSTEM privileges, an authenticated user with any role can execute arbitrary OS commands on monitored endpoints, leading to full compromise of those systems.
Potential Impact
An authenticated user, regardless of their assigned role, can execute arbitrary operating-system commands on endpoints monitored by UTMStack agents. Because these agents commonly run with root or SYSTEM privileges, this vulnerability can lead to complete system compromise, including confidentiality, integrity, and availability impacts. The CVSS score of 9.9 reflects the critical nature of this vulnerability with network attack vector, low attack complexity, and no user interaction required.
Mitigation Recommendations
No explicit patch or remediation information is provided in the input data. Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. Until a fix is available, restrict authenticated user access to trusted personnel only and monitor for unusual command activity related to the /command/{hostname} STOMP destination.
