AI-suggested

Upgrade ntopng to version 6.7.260717 or later, where this vulnerability is fixed. Until upgraded, restrict access to the vulnerable endpoints to trusted administrators only and consider disabling the vulnerability scan feature if feasible. Note that the vulnerability can be exploited via GET requests bypassing CSRF protections, so additional network-level controls may be necessary to mitigate risk.

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.
