Symantec Web Gateway < 5.2.5 Management Console Command Injection (SYM16-017)

high Nessus Plugin ID 94052

Language:

Synopsis

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

Description

According to its self-reported version number, the Symantec Web Gateway application hosted on the remote web server is prior to 5.2.5.
It is, therefore, affected by a flaw in the web-based management console interface, specifically within the /spywall/new_whitelist.php script, due to improper whitelist validation checks. An authenticated, remote attacker can exploit this, via a specially crafted request, to make unauthorized whitelist entries and to execute arbitrary commands with 'root' privileges.

Solution

Upgrade to Symantec Web Gateway version 5.2.5 or later.
