Froxlor Server Management Panel 0.10.16 contains a persistent cross-site scripting vulnerability in customer registration input fields. Attackers can inject malicious scripts through username, name, and firstname parameters to execute code when administrators view customer traffic modules.

Froxlor is open source server administration software. Prior to version 2.1.2, it was possible to submit the registration form with the essential fields, such as the username and password, left intentionally blank. This inadvertent omission allowed for a bypass of the mandatory field requirements (e.g. surname, company name) established by the system. Version 2.1.2 fixes this issue.
