Details

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.
