Description

On diag_ping.php, the hostname isn't fully validated and the output is not encoded, leading to a potential XSS.

Using an input such as the following example demonstrates the problem:

127.0.0.1 <img src='' onerror='alert()'>

diag_traceroute.php is unaffected but I made the same changes there to be safe.
