CKEditor 41.3.0 < 44.2.1 XSS

low Nessus Plugin ID 216916

Synopsis

The remote web server may be affected by a cross site scripting vulnerability.

Description

The version of CKEditor included on the remote web host is 41.3.0 prior to 44.2.1. It may, therefore, be affected by a cross-site scripting (XSS) vulnerability. This vulnerability affects user markers, which represent users' positions within the document. It can lead to unauthorized JavaScript code execution, which might happen with a very specific editor and token endpoint configuration. This vulnerability affects only installations with Real-time collaborative editing enabled. The problem has been recognized and patched. The fix is available in version 44.2.1 (and above). Users are advised to upgrade. There are no known workarounds for this vulnerability.

Note that Nessus has not tested for this issue but has instead relied only on the application's self-reported version number.

Solution

Upgrade to CKEditor 44.2.1 or later.
