XWiki Improper Neutralization of Special Elements in Output Used by a Downstream Component (Injection) Vulnerability - CVE-2023-29525
XWiki Platform is a generic wiki platform offering runtime services for applications built on top of it. Affected versions of xwiki are subject to code injection in the since parameter of the /xwiki/bin/view/XWiki/Notifications/Code/LegacyNotificationAdministration endpoint. This provides an XWiki syntax injection attack via the since-parameter allowing privilege escalation from view to programming rights and subsequent code execution privilege. The vulnerability has been patched in XWiki 15.0-rc-1 14.10.3 14.4.8 and 14.10.3. Users are advised to upgrade. Users unable to upgrade may modify the page XWiki.Notifications.Code.LegacyNotificationAdministration to add the missing escaping. For versions lt 14.6-rc-1 a workaround is to modify the file ltxwikiwebappgt/templates/distribution/eventmigration.wiki to add the missing escaping.
