CVE-2023-37909

Summary

CVE-2023-37909 is a vulnerability affecting the XWiki Platform, a wiki solution that provides runtime services for applications. This issue, present in versions 5.1-rc-1 and earlier, allows any user with editing privileges on their profile to execute arbitrary script macros, including Groovy and Python, leading to remote code execution. Consequently, attackers can gain unrestricted read and write access to all wiki contents. The vulnerability has been addressed in XWiki versions 14.10.8 and 15.3-rc-1 through proper escaping. As a temporary solution, users can manually apply the patch to the `Menu.UIExtensionSheet` document by modifying just three lines.
