Summary

XWiki Remote Macros versions 1.0 through before 1.26.5 fail to escape the width parameter in the column macro, allowing XWiki syntax injection. This enables remote code execution for users who can edit pages or access the CKEditor converter.

Risk Assessment

An attacker can execute arbitrary code (including Velocity) with wiki admin privileges, potentially leading to full compromise of the XWiki platform.

Recommendation

Update XWiki Remote Macros to version 1.26.5 or later. Restrict page edit permissions and access to the CKEditor converter.

Original NVD description (English source)

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 width parameter in the column macro allows remote code execution for any user who can edit any page or who can access the CKEditor converter. The width parameter is used without escaping in XWiki syntax, thus allowing XWiki syntax injection which enables remote code execution when the macro has been installed by a user with programming right, or it at least allows executing Velocity code as the wiki admin. Version 1.26.5 contains a patch for the issue.
