Nessus Client 4.x < 4.2.0 QtWeb Path Subversion DLL Injection Local Code Execution

high Nessus Plugin ID 89028

Language:

Synopsis

The remote Nessus Client is affected by a local code execution vulnerability.

Description

According to its version, the installation of Tenable Nessus Client on the remote Windows host is version 4.x prior to 4.2.0. It is, therefore, affected by a local code execution vulnerability in the bundled version of QtWeb. QtWeb loads dynamic-link libraries using a fixed path to look for specific files or libraries. A local attacker can exploit this by placing a custom DLL file in the path, resulting in the execution of arbitrary code.

Solution

Upgrade to the current release of Nessus and uninstall the Nessus Client.
