'Name' => "Symantec Web Gateway 5.0.2.8 Command Execution Vulnerability",

'Description'=> %q{

This module exploits a vulnerability found in Symantec Web Gateway's HTTP

service.By injecting PHP code in the access log, it is possible to load it

with a directory traversal flaw, which allows remote code execution under the

context of 'apache'. Please note that it may take up to several minutes to

retrieve access_log, which is about the amount of time required to see a shell

back.
