According to its self-reported version number, the detected Drupal application is affected by a cross-site scripting (XSS) vulnerability in the Enhanced Image (aka image2) plugin for CKEditor.

Note that the scanner has not tested for these issues but has instead relied only on the application's self-reported version number.

The version of CKEditor installed on the remote host is affected by a cross-site scripting vulnerability.

The included 'Enhanced Image' plugin causes CKEditor to fail to properly sanitize user-supplied input. A remote, unauthenticated attacker can leverage this issue to inject arbitrary HTML and script code into a user's browser to be executed within the security context of the affected site.
