Securechange Cross-site Scripting

Tufin SecureChange prior to R19.3 HF3 and R20-1 HF1 are vulnerable to stored XSS. The successful exploitation requires admin privileges (for storing the XSS payload itself), and can exploit (be triggered by) admin users. All TOS versions with SecureChange deployments prior to R19.3 HF3 and R20-1 HF1 are affected. Vulnerabilities were fixed in R19.3 HF3 and R20-1 HF1. (2021-01-20, CVE-2020-13134)

Cross site scripting is an attack where a web page executes code that is injected by an adversary. It usually appears, when users input is presented. This attack can be used to impersonate a user, take over control of the session, or even steal API keys.

The attack can be executed e.g. when you application injects the request parameter directly into the HTML code of the page returned to the user:

https://server.com/confirmation?message=Transaction+Complete

what results in:

<span>Confirmation: Transaction Complete</span>

In that case the message can be modified to become a valid Javascript code, e.g.:

https://server.com/confirmation?message=<script>dangerous javascript code here</script>

and it will be executed locally by the user's browser with full access to the user's personal application/browser data:

<span>Confirmation: <script>dangerous javascript code here</script></span>
