Description of the vulnerability

The account name is not properly sanitized and can execute Javascript code when reflected in the website. I've opened an issue in GitHub issue tracker (https://github.com/totaljs/openplatform/issues/52) and after few hours the maintainer provided a patch (https://github.com/totaljs/openplatform/commit/b6a128a5cc130394ca8c397db01a6e53b64c0948).

Replication of the vulnerability

  • Login in the application.
  • Click on user profile picture in the right corner below.
  • Click My Account
  • Set "><img src=x onerror=alert(document.domain)> as account name and save.
  • XSS fires.
  • Each time a target will visit the dashboard the payload will fire, even if the target is not logged in! In order to test this, just click logout and reload the page.
