filefieldmodule-filepath-xss (59500) The risk level is classified as MediumMedium Risk

Description:

FileField module for Drupal is vulnerable to cross-site scripting, caused by improper validation of user-supplied input. If the administrator has configured a vulnerable display format or users a special token, then a remote attacker with permission to create or edit content with FileField could exploit this vulnerability using the filepath parameter to inject malicious script into a Web page which would be executed in a victim's Web browser within the security context of the hosting Web site, once the page is viewed. An attacker could use this vulnerability to steal the victim's cookie-based authentication credentials.
