iManager Plugin v1.2.8 (d) Remote Arbitrary File Deletion Vulnerability

Vendor: net4visions.com
Product web page: http://www.net4visions.com
Affected version: <= 1.2.8 Build 02012008

Summary: With iManager you can manage your files/images on your webserver,
and it provides user interface to most of the phpThumb() functions. It works
either stand-alone or as a plugin to WYSIWYG editors like tinyMCE, SPAW,
htmlAREA, Xinha and FCKeditor.

Desc: Input passed to the 'd' parameter in /scripts/phpCrop/crop.php is not
properly sanitised before being used to delete files. This can be exploited
to delete files with the permissions of the web server via directory traversal
sequences passed within the 'd' parameter.


======================================================================
/scripts/phpCrop/crop.php:
----------------------------------------------------------------------

32: if( isset($_REQUEST['s']) ) {
33:     //delete previous temp files       
34:     $matches = glob($d . '{*.jpg,*.JPG}', GLOB_BRACE);     
35:     if ( is_array ( $matches ) ) {
36:          foreach ( $matches as $fn) {
37:               @unlink($fn);
38:          }
39: }
