Linux Distros Unpatched Vulnerability : CVE-2025-66399

medium Nessus Plugin ID 277092

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.

- Cacti is an open source performance and fault management framework. Prior to 1.2.29, there is an input- validation flaw in the SNMP device configuration functionality. An authenticated Cacti user can supply crafted SNMP community strings containing control characters (including newlines) that are accepted, stored verbatim in the database, and later embedded into backend SNMP operations. In environments where downstream SNMP tooling or wrappers interpret newline-separated tokens as command boundaries, this can lead to unintended command execution with the privileges of the Cacti process. This vulnerability is fixed in 1.2.29. (CVE-2025-66399)

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

Solution

There is no known solution at this time.
