[{'type': 'paragraph', 'content': 'CVE-2025-56605 is a reflected Cross-Site Scripting (XSS) vulnerability in the register.php backend script of the PuneethReddyHC Event Management System version 1.0. The issue occurs because the mobile POST parameter is not properly validated or sanitized before being echoed back in the HTTP response.'}, {'type': 'paragraph', 'content': "This improper handling allows an attacker to inject arbitrary JavaScript code via a crafted POST request. When the victim's browser receives the response, the malicious script executes, potentially compromising the user's session or data."}] [1]

How can this vulnerability be detected on my network or system? Can you suggest some commands?
[{'type': 'paragraph', 'content': 'This vulnerability can be detected by sending a crafted POST request to the register.php backend script with a malicious payload in the mobile parameter and observing if the payload is reflected unsanitized in the HTTP response.'}, {'type': 'paragraph', 'content': 'For example, you can use the curl command to test for the vulnerability by sending a POST request with a JavaScript payload in the mobile parameter and checking if it appears in the response without encoding.'}, {'type': 'list_item', 'content': 'curl -X POST -d "mobile=<script>alert(\'XSS\')</script>" http://target-site/backend/register.php -i'}, {'type': 'paragraph', 'content': 'If the response contains the script tags and JavaScript code without any HTML entity encoding, the system is vulnerable to reflected XSS.'}] [1]
What immediate steps should I take to mitigate this vulnerability?
[{'type': 'paragraph', 'content': 'To mitigate this vulnerability, you should sanitize or encode the user input before outputting it in the HTTP response.'}, {'type': 'paragraph', 'content': "Specifically, applying PHP's htmlspecialchars function on the mobile POST parameter will encode special characters and prevent script injection."}, {'type': 'list_item', 'content': "Use: echo htmlspecialchars($_POST['mobile'], ENT_QUOTES, 'UTF-8');"}, {'type': 'paragraph', 'content': 'This ensures that any HTML or JavaScript code submitted via the mobile parameter is safely encoded and not executed by the browser.'}] [1]
