Summary
org.xwiki.platform:xwiki-platform-flamingo-theme-ui Eval Injection vulnerability
Details

Impact

Any user with view rights on commonly accessible documents can execute arbitrary Groovy, Python or Velocity code in XWiki leading to full access to the XWiki installation. The root cause is improper escaping of the documentTree macro parameters in This macro is installed by default in FlamingoThemesCode.WebHome. This page is installed by default.

Example of reproduction: Open <xwiki_host>/xwiki/bin/view/%22%20%2F%7D%7D%20%7B%7Basync%20async%3D%22true%22%20cached%3D%22false%22%20context%3D%22doc.reference%22%7D%7D%7B%7Bgroovy%7D%7Dprintln(%22Hello%20%22%20%2B%20%22from%20groovy!%22)%7B%7B%2Fgroovy%7D%7D%7B%7B%2Fasync%7D%7D?sheet=FlamingoThemesCode.WebHome&xpage=view where <xwiki_host> is the URL of your XWiki installation.

The [documentTree] macro is a standalone macro and it cannot be used inline. Click on this message for details. Hello from groovy!.WebHome" /}}

is displayed. This shows that the Groovy macro that is passed in the URL has been executed and thus demonstrates a privilege escalation from view to programming rights.

Patches

The vulnerability has been patched in XWiki 13.10.11, 14.4.7 and 14.10.

Workarounds
