Symantec Web Gateway Multiple Script Shell Command Execution (SYM12-011)

critical Nessus Plugin ID 61435
New! Plugin Severity Now Using CVSS v3

The calculated severity for Plugins has been updated to use CVSS v3 by default. Plugins that do not have a CVSS v3 score will fall back to CVSS v2 for calculating severity. Severity display preferences can be toggled in the settings dropdown.

Synopsis

The remote host is affected by a shell command execution vulnerability.

Description

The Symantec Web Gateway install on the remote host is affected by a remote shell command execution vulnerability due to its failure to sanitize input to the 'ip' parameter of the 'fromha.php' script.

An unauthenticated, remote attacker can exploit this vulnerability to save a random PHP script on the affected host and then execute that as a privileged user.

Note that this install is likely affected by several other issues, although this plugin has not checked for them.

Solution

Upgrade to Symantec Web Gateway version 5.0.3.18 and apply database upgrade 5.0.0.438.
