Synopsis

The Linux/Unix host has one or more packages installed with a vulnerability that the vendor indicates will not be patched.

Description

The Linux/Unix host has one or more packages installed that are impacted by a vulnerability without a vendor supplied patch available.

 - 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-2026-84989)

Note that Nessus relies on the presence of the package as reported by the vendor.
