What to do

AI-suggested

1. Immediate upgrade to xwiki-pro-macros version 1.26.5 or later, where the vulnerability is patched. 2. Restrict edit permissions on XWiki pages to trusted users only, minimizing the number of users who can exploit the vulnerability. 3. Implement web application firewalls (WAFs) with custom rules to detect and block suspicious macro usage or injection patterns related to the ConfluenceLayoutSection macro. 4. Conduct thorough audits of existing XWiki instances to identify and remediate any unauthorized or suspicious content injections. 5. Employ network segmentation and least privilege principles to limit the potential lateral movement if exploitation occurs. 6. Monitor logs and alerts for unusual activity related to XWiki editing and macro usage. 7. Educate administrators and users about the risks of editing macros and the importance of applying security patches promptly.

Description

XWiki Remote Macros provides XWiki rendering macros that are useful when migrating content from Confluence. Starting in version 1.0 and prior to version 1.26.5, missing escaping of the ac:type in the ConfluenceLayoutSection macro allows remote code execution for any user who can edit any page The classes parameter is used without escaping in XWiki syntax, thus allowing XWiki syntax injection which enables remote code execution. Version 1.26.5 has a fix for the issue.
