Tenable Nessus < 10.8.4 Privilege Escalation (TNS-2025-05)

high Nessus Plugin ID 234838

Synopsis

An instance of Nessus installed on the remote system is affected by privilege escalation vulnerability.

Description

According to its self-reported version, the Tenable Nessus application running on the remote host is prior to 10.8.4. It is, therefore, affected by a vulnerability as referenced in the TNS-2025-05 advisory.

- When installing Nessus to a non-default location on a Windows host, Nessus versions prior to 10.8.4 did not enforce secure permissions for sub-directories. This could allow for local privilege escalation if users had not secured the directories in the non-default installation location. (CVE-2025-24914)

Note that Nessus has not tested for this issue but has instead relied only on the application's self-reported version number.

Solution

Upgrade to Tenable Nessus 10.8.4 or later.
