Severity: Medium
Vulnerability Published: 2014-10-07
Patch Published: 2014-06-13
CVE [?]: CVE-2014-7280
CPE [?]: cpe:/a:tenable:nessus

Synopsis

A web server running on the remote host is affected by a cross-site scripting vulnerability.

Description

According to its self-reported version number, the Nessus web server running on the remote host is affected by a cross-site scripting vulnerability in the web-based user interface (Web UI) due to improper validation of input passed from plugins before returning it users. A remote attacker can exploit this, via a specially crafted request, to execute arbitrary script code in a user's browser session.

Solution

Upgrade the plugin feed using 'nessus-update-plugins', restart the web server, and verify Nessus Web UI version 2.3.4 (#85) or later is running. The Web UI version can be viewed by logging in and clicking the 'About' button.
