PHP Server Monitor, version 3.2.0, is vulnerable to an XSS via the /phpservermon-3.2.0/vendor/phpmailer/phpmailer/test_script/index.php page in all visible parameters. An attacker could create a specially crafted URL, send it to a victim and retrieve their session details.
Solution:
The product does not neutralize or incorrectly neutralizes user-controllable input before it is placed in output that is used as a web page that is served to other users.
