Nessus versions 8.15.2 and earlier were found to contain a local privilege escalation vulnerability which could allow an authenticated, local administrator to run specific executables on the Nessus Agent host. Tenable has included a fix for this issue in Nessus 10.0.0. The installation files can be obtained from the Tenable Downloads Portal (https://www.tenable.com/downloads/nessus).

According to its self-reported version, the Tenable Nessus application running on the remote host is prior or equal to 8.15.2. It is, therefore, affected by a local privilege escalation vulnerability which could allow an authenticated, local administrator to run specific executables on the Nessus Agent host.

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