|
|
'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.
