How it was found

Greetings,

I've discovered a DOM-based XSS at ███

Proof of concept:

1. Go to https://████/█████████/home/troubleshoot.html?lang=en 2. In the username field, add the following code:

--><button/autofocus/onfocus=Function("confirm`1`")();//name="XSS

3. The javascript code is correctly executed:

██████

With this vulnerability, an attacker can for example steal users cookies or redirect users on malicious website.

Thanks for your attention and let me know if you need anything. Regards, Yumi
