Any authenticated user, regardless of role, can send arbitrary operating-system commands over gRPC to any connected agent, resulting in command execution on monitored endpoints where agent processes commonly run as root or SYSTEM.","cvssScore":9.9,"cvssSeverity":"CRITICAL","cvssVector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:C/C:H/I:H/A:H","cwes":["CWE-862"],"vendors":[],"products":[],"references":[{"url":"https://github.com/UTMStack/UTMStack/releases/tag/v11.2.16","tags":[]},{"url":"https://github.com/utmstack/UTMStack/commit/4e7a727c3b8d8e2ad020d3b4f982a6d085dbecdd","tags":[]},{"url":"https://www.vulncheck.com/advisories/utmstack-missing-authorization-via-command-websocket","tags":[]}],"exploitRefs":[{"url":"https://github.com/UTMStack/UTMStack/releases/tag/v11.2.16","tags":[]},{"url":"https://github.com/utmstack/UTMStack/commit/4e7a727c3b8d8e2ad020d3b4f982a6d085dbecdd","tags":[]}],"hasPoc":true,"ai":{"summary":"This vulnerability allows any authenticated user to execute arbitrary commands on connected agents, posing a significant risk due to the lack of role-based authorization checks.","exploitability":"Exploitation is relatively straightforward as it requires authentication but no specific role is needed, making it accessible to any logged-in user.","blast_radius":"The impact is high as it can lead to complete control over monitored endpoints, potentially leading to data exfiltration, system compromise, or denial of service.","remediation":"Upgrade to UTMStack 11.2.16 or later immediately.","detection":"Monitor authentication logs for unusual command execution attempts or unexpected network traffic patterns related to STOMP destinations.","tags":["rce","auth-bypass","web","grpc"],"model":"qwen2.5:7b-instruct","analyzedAt":"2026-10-03T08:43:47.092Z"}}
