{"id":"AZL-103404","summary":"CVE-2026-83621 affecting package ntopng 5.2.1-6","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.","modified":"2026-09-23T05:36:13Z","published":"2026-09-21T17:19:08Z","upstream":["CVE-2026-83621"],"references":[{"type":"WEB","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-83621"}],"affected":[{"package":{"name":"ntopng","ecosystem":"Azure Linux:3","purl":"pkg:rpm/azure-linux/ntopng"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"last_affected":"5.2.1-6"}]}],"database_specific":{"source":"https://github.com/microsoft/AzureLinuxVulnerabilityData/blob/main/osv/AZL-103404.json"}}],"schema_version":"1.9.0"}
