CityPost PHP Image Editor M2 URI Parameter Cross-Site Scripting Vulnerability

source: http://www.securityfocus.com/bid/13257/info

CityPost Image Cropper/Resizer is affected by a cross-site scripting vulnerability. This issue is due to a failure in the application to properly sanitize user-supplied input to the 'image-editor-52.php' script.

An attacker may leverage this issue to have arbitrary script code executed in the browser of an unsuspecting user. This may facilitate the theft of cookie-based authentication credentials as well as other attacks.
