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

high Nessus Plugin ID 89028


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


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.


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