CVE-2026-84990 High · 8.8 CWE-200 Sep 21, 2026
ntopng: Missing Authorization on System Configuration Backup Download and Listing
ntopng is a web-based network traffic monitoring application. Prior to 6.7.260718, scripts/lua/rest/v2/get/system/configurations/list_available_backups.lua and scripts/lua/rest/v2/get/system/configurations/download_backup.lua allow any authenticated non-admin user to list and download system-configuration backups without an administrator check. The download path reaches backup_config.export_backup, and prefs_dump_utils.build_prefs_dump_table includes the ntopng.user.* Redis key space in the backup. A downloaded backup can therefore disclose password hashes for local users and, when configured, API tokens, TOTP secrets, and WebAuthn credential data, enabling account compromise through usable or recoverable credentials. This issue is fixed in version 6.7.260718.
CVE-2026-83621 High · 8.1 CWE-862 Sep 21, 2026
ntopng: Missing Authorization Check in REST API Allows Non-Admin Users to Tamper Threat Intelligence Blacklist URLs
ntopng is a web-based network traffic monitoring application. Prior to 6.7.260717, POST /lua/rest/v2/edit/system/edit_blacklist.lua in scripts/lua/rest/v2/edit/system/edit_blacklist.lua lacks an administrator check and calls lists_utils.editList for any authenticated user. The list_name, list_enabled, url, and list_update parameters allow a non-admin user to redirect threat-intelligence downloads to attacker-controlled content, disable blocklists, or prevent scheduled updates. The changes are persisted through Redis and reloaded without a lower-level authorization guard, undermining the integrity and availability of ntopng's threat-intelligence monitoring. This issue is fixed in version 6.7.260717.
CVE-2026-82412 High · 8.8 CWE-78 Sep 21, 2026
ntopng: Remote Code Execution via OS Command Injection in Vulnerability-Scan REST API
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.
CVE-2026-86091 High · 7.1 CWE-862 Sep 4, 2026
ntopng before 6.7.260717 Missing Authorization on the Host Pool Bulk Delete Handler
ntopng before 6.7.260717 fails to check user privileges in the pools bulk-delete endpoint, allowing authenticated non-administrators to delete all host pools and member bindings. Attackers can issue POST requests to the delete pools endpoint to irreversibly destroy every host pool, removing traffic policy bindings and visibility restrictions that may bypass security policies.
CVE-2026-86090 High · 7.1 CWE-862 Sep 4, 2026
ntopng before 6.7.260717 Missing Authorization on the Notification Endpoint and Recipient Delete Handlers
ntopng before 6.7.260717 fails to perform authorization checks in the delete endpoints and recipients REST v2 handlers. Authenticated non-administrator users can issue POST requests to irreversibly delete all configured notification endpoints and recipients, silencing all alerts.
CVE-2026-84989 High · 7.1 CWE-862 Sep 3, 2026
ntopng's Missing Authorization in REST API Allows Non-Admin Users to Delete and Rename Arbitrary Tags
ntopng is a web-based network traffic monitoring application. In versions 6.7.0 through 6.7.260717, two REST v2 endpoints that manage ntopng's tag/badge feature — `POST /lua/rest/v2/delete/tag/tag.lua` and `POST /lua/rest/v2/edit/tag/tag.lua` — perform no authorization check at all. Any authenticated user, including a non-administrator ("unprivileged") account, can delete or rename any tag in the system, including tags created by an administrator. Version 6.7.260718 contains a fix.
CVE-2026-38968 Critical · 9.8 CWE-341 Jul 2, 2026
ntopng through 6.6 is vulnerable to Predictable Session Identifier which can lead to…
ntopng through 6.6 is vulnerable to Predictable Session Identifier which can lead to Session Hijacking. HTTP session identifiers in src/HTTPserver.cpp use weak time-seeded pseudo-randomness during session creation. As a result, fresh authenticated logins can receive deterministic or colliding session cookies under attacker-controlled timing.
