Synopsis

Tenable Nessus running on the remote host is affected by a privilege escalation vulnerability.

Description

According to its self-reported version, the Tenable Nessus application running on the remote host is prior to 8.14.0. It is, therefore, affected by a privilege escalation vulnerability. An authenticated attacker can exploit this, via file upload, to gain administrator privileges to the system.
