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 8.3.4 or 10.x prior to 10.1.4. It is, therefore, affected by multiple vulnerabilities:

 - An authenticated attacker could create an audit file that bypasses PowerShell cmdlet checks and executes commands with administrator privileges. (CVE-2022-32973)

 - An authenticated attacker could read arbitrary files from the underlying operating system of the scanner using a custom crafted compliance audit file without providing any valid SSH credentials. (CVE-2022-32974)

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 Agent version 8.3.4 or 10.1.4 or later.
