Vulnerability Title
org.xwiki.contrib:application-ckeditor-ui vulnerable to Remote Code Execution via Cross-Site Request Forgery
Source: CVE Program / CVE List V5
Vulnerability Description
CKEditor Integration UI adds support for editing wiki pages using CKEditor. Prior to versions 1.64.3,t he `CKEditor.HTMLConverter` document lacked a protection against Cross-Site Request Forgery (CSRF), allowing to execute macros with the rights of the current user. If a privileged user with programming rights was tricked into executing a GET request to this document with certain parameters (e.g., via an image with a corresponding URL embedded in a comment or via a redirect), this would allow arbitrary remote code execution and the attacker could gain rights, access private information or impact the availability of the wiki. The issue has been patched in the CKEditor Integration version 1.64.3. This has also been patched in the version of the CKEditor integration that is bundled starting with XWiki 14.6 RC1. There are no known workarounds for this other than upgrading the CKEditor integration to a fixed version.
