Описание
XWiki Platform vulnerable to remote code execution via the edit action because it lacks CSRF token
Impact
In XWiki Platform, it's possible to execute content with the right of any user if you can make this user follow a crafted URL. This is possible because edit action sets and thereby executes the page content without checking for a cross-site request forgert (CSRF) token.
To reproduce:
Get a user with programming rights to visit the URL <xwiki-host>/xwiki/bin/edit/Main/?content=%7B%7Bgroovy%7D%7Dprintln%28%22Hello+from+Groovy%21%22%29%7B%7B%2Fgroovy%7D%7D&xpage=view, where <xwiki-host> is the URL of your XWiki installation. This can be done by embedding an image with this URL.
The text "Hello from Groovy!" is displayed in the page content, showing that the Groovy macro has been executed.
Patches
This has been patched in XWiki 14.10.7 and 15.2-RC-1.
Workarounds
There are no known workarounds for it.
