{"id":"AZL-112702","summary":"CVE-2026-82413 affecting package ntopng 5.2.1-7","details":"ntopng is a web-based network traffic monitoring application. Prior to 6.7.260717, scripts/lua/rest/v2/add/host/to_scan.lua and scripts/lua/rest/v2/exec/host/schedule_vulnerability_scan.lua accept scan_ports from any authenticated session, including non-administrator users, while deployments with login disabled expose the same request without authentication. The endpoints validate scan_ports with validateSingleWord, which permits shell metacharacters, and persist the value for the minute vulnerability-scan scheduler. The scheduler concatenates the value into an nmap command through nmap_scan_host and executes it through ntop.execCmd or ntop.execCmdAsync using popen. For the tcp_portscan and cve modules, a preliminary nmap -sn probe must first report the target as up before the attacker-controlled ports are used. When nmap is installed, this command injection allows arbitrary operating-system commands to execute as the ntopng service account without further user interaction. This issue is fixed in version 6.7.260717.","modified":"2026-11-06T14:17:03.915911167Z","published":"2026-11-05T17:18:21Z","upstream":["CVE-2026-82413"],"references":[{"type":"WEB","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-82413"}],"affected":[{"package":{"name":"ntopng","ecosystem":"Azure Linux:3","purl":"pkg:rpm/azure-linux/ntopng"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"last_affected":"5.2.1-7"}]}],"database_specific":{"source":"https://github.com/microsoft/AzureLinuxVulnerabilityData/blob/main/osv/AZL-112702.json"}}],"schema_version":"1.9.2"}
