high Nessus Plugin ID 197302

Synopsis

An instance of Nessus Agent installed on the remote system is affected by multiple vulnerabilities.

Description

According to its self-reported version, the Tenable Nessus Agent running on the remote host is prior to 10.6.4. It is, therefore, affected by multiple vulnerabilities as referenced in the TNS-2024-09 advisory.

- Two separate vulnerabilities were discovered, reported and fixed:When installing Nessus Agent to a directory outside of the default location on a Windows host, Nessus Agent versions prior to 10.6.4 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-2024-3291A race condition vulnerability exists where an authenticated, local attacker on a Windows Nessus Agent host could modify installation parameters at installation time, which could lead to the execution of arbitrary code on the Nessus host. - CVE-2024-3292 Tenable has released Nessus Agent 10.6.4 to address these issues. The installation files can be obtained from the Tenable Downloads Portal (https://www.tenable.com/downloads/nessus-agents). (CVE-2024-3291, CVE-2024-3292)

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

Solution

Upgrade to Tenable Nessus Agent 10.6.4 or later.
