  • Disclosed: 19.08.2024
  • Updated: 11.10.2026 12:21

Impact

Is it possible for a user without Script or Programming rights to craft a URL pointing to a page with arbitrary JavaScript. This requires social engineer to trick a user to follow the URL.

Reproduction steps

  1. As a user without script or programming right, create a (non-terminal) document named " + alert(1) + " (the quotes need to be part of the name).
  2. Edit the class.
  3. Add a string property named "test".
  4. Edit using the object editor and add an object of the created class
  5. Get an admin to open <xwiki-server>/xwiki/bin/view/%22%20%2B%20alert(1)%20%2B%20%22/?viewer=display&type=object&property=%22%20%2B%20alert(1)%20%2B%20%22.WebHome.test&mode=edit where <xwiki-server> is the URL of your XWiki installation.
