What to do
AI-suggested
1. Immediate upgrade to xwiki-pro-macros version 1.26.5 or later, where the vulnerability is patched. 2. If upgrading is not immediately feasible, implement strict access controls to restrict page editing permissions only to trusted users to reduce the attack surface. 3. Employ Web Application Firewalls (WAFs) with custom rules to detect and block suspicious XWiki syntax injection patterns targeting the 'classes' parameter. 4. Conduct thorough code reviews and input validation audits for any custom macros or extensions that handle user input to ensure proper escaping and encoding. 5. Monitor logs for unusual editing activity or syntax injection attempts, and establish alerting mechanisms for anomalous behavior. 6. Isolate XWiki instances in segmented network zones to limit potential lateral movement in case of compromise. 7. Educate administrators and users about the risks of editing pages with untrusted content and enforce security best practices for collaborative platforms. 8. Regularly back up XWiki data and configurations to enable rapid recovery in case of exploitation.
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 title in the confluence paste code 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.
