Title: phpThumb() 'fltr[]' Parameter Command Injection Vulnerability

Severity: HIGH


phpThumb() is an application used to create thumbnails from images.

The application is prone to a command-injection vulnerability because it fails to adequately sanitize user-supplied input to the 'fltr[]' parameter in the 'phpThumb.php' script.

Attackers can exploit this issue to execute arbitrary commands in the context of the webserver.

Note that successful exploitation requires 'ImageMagick' to be installed.

phpThumb() 1.7.9 is affected; other versions may also be vulnerable.

Affected Products:

  • phpThumb phpThumb() 1.7.9
