CVE [?]: CVE-2014-7285
CPE [?]: cpe:/a:symantec:web_gateway

Synopsis

A web security application hosted on the remote web server is affected by a OS command injection vulnerability.

Description

According to its self-reported version number, the remote web server is hosting a version of Symantec Web Gateway prior to version 5.2.2. It is, therefore, affected by a operating system (OS) command injection vulnerability in an unspecified PHP script which impacts the management console. A remote, authenticated user can exploit this issue to execute arbitrary OS commands subject to the privileges of the authenticated user.

Solution

Upgrade to Symantec Web Gateway 5.2.2 or later.
