{"id":"CVE-2026-82412","published":"2026-09-21T16:17:24.503","lastModified":"2026-09-21T21:17:13.470","description":"ntopng is a web-based network traffic monitoring application. Prior to 6.7.260717, the vulnerability-scan endpoints scripts/lua/rest/v2/add/host/to_scan.lua and scripts/lua/rest/v2/exec/host/schedule_vulnerability_scan.lua accept the scan_ports parameter without an administrator gate and pass it through validateSingleWord, which permits shell metacharacters. scripts/lua/modules/vulnerability_scan/vs_utils.lua then concatenates scan_ports into an nmap command in nmap_scan_host and executes the command through ntop.execCmd or ntop.execCmdAsync and popen. Any authenticated non-admin user can execute operating-system commands as the ntopng process account when nmap is available. Because the endpoints accept GET requests while ntopng's CSRF validation applies to POST request bodies, an attacker can also trigger the command through a logged-in user's browser without possessing ntopng credentials. This issue is fixed in version 6.7.260717.","cvssScore":8.8,"cvssSeverity":"HIGH","cvssVector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H","cwes":["CWE-78"],"vendors":[],"products":[],"references":[{"url":"https://github.com/ntop/ntopng/commit/0d3156274f4d12db8b61432ebeded10966c01f3e","tags":[]},{"url":"https://github.com/ntop/ntopng/commit/771b34a9d37f5de989eec4f2f8f2e852db1c7e5e","tags":[]},{"url":"https://github.com/ntop/ntopng/commit/838ccd523a3d4a71b29a62f7653e572a1ffa5cf6","tags":[]},{"url":"https://github.com/ntop/ntopng/commit/9f42a12251d881e3a20ebd667c1a2e6a6570c270","tags":[]},{"url":"https://github.com/ntop/ntopng/security/advisories/GHSA-2c6p-4pfj-qv58","tags":[]}],"exploitRefs":[{"url":"https://github.com/ntop/ntopng/commit/0d3156274f4d12db8b61432ebeded10966c01f3e","tags":[]},{"url":"https://github.com/ntop/ntopng/commit/771b34a9d37f5de989eec4f2f8f2e852db1c7e5e","tags":[]},{"url":"https://github.com/ntop/ntopng/commit/838ccd523a3d4a71b29a62f7653e572a1ffa5cf6","tags":[]},{"url":"https://github.com/ntop/ntopng/commit/9f42a12251d881e3a20ebd667c1a2e6a6570c270","tags":[]},{"url":"https://github.com/ntop/ntopng/security/advisories/GHSA-2c6p-4pfj-qv58","tags":[]}],"hasPoc":true,"ai":{"summary":"The vulnerability allows any authenticated non-admin user to execute OS commands as the ntopng process account via crafted GET requests, leading to potential unauthorized access and control of the system.","exploitability":"Exploitation is relatively straightforward given that an attacker can trigger the command through a logged-in user's browser without needing ntopng credentials.","blast_radius":"If exploited, this could result in significant damage as it grants attackers the ability to execute arbitrary commands on the server hosting ntopng.","remediation":"Update to version 6.7.260717 or later to mitigate the vulnerability.","tags":["rce","auth-bypass","web","os-command-injection"],"model":"qwen2.5:7b-instruct","analyzedAt":"2026-09-22T06:04:13.924Z"}}
