The Kaseya version 18.104.22.168 web interface (and possibly other versions) is vulnerable to Cross-Site Scripting in the “adminName” variable.
3. Proof of Concept
Use a HTML proxy such as WebScarab or Burp to intercept the HTML form post as it is submitted, and replace the “adminName” with the input above.
5. Affected Products
