'Name' => "SePortal SQLi Remote Code Execution",
'Description'=> %q{
This module exploits a vulnerability found in SePortal version 2.5.
When logging in as any non-admin user, it's possible to retrieve the admin session
from the database through SQL injection. The SQL injection vulnerability exists
in the "staticpages.php" page. This hash can be used to take over the admin
user session. After logging in, the "/admin/downloads.php" page will be used
to upload arbitrary code.
