Can you explain this vulnerability to me?

CVE-2024-51223 is a stored cross-site scripting (XSS) vulnerability in the admin profile page (/admin/profile.php) of the Phpgurukul Vehicle Record Management System v1.0.

The vulnerability occurs because the Mobile Number parameter accepts user input without any sanitization, type validation, or output encoding. This allows an attacker to inject malicious scripts into the mobile field.

The injected script is stored persistently in the database and executes every time the profile page is loaded, affecting all users who view it.

Technically, the vulnerable variable is assigned directly from user POST data without validation, and the input is rendered without encoding, making arbitrary JavaScript execution possible.

How can this vulnerability impact me? :

This vulnerability can have several serious impacts:

• Persistent session hijacking through theft of cookies.
• Privilege escalation by executing admin-level actions via injected JavaScript.
• Information disclosure by exfiltrating sensitive data from the admin dashboard.
• Phishing attacks or redirection of users to attacker-controlled websites.
• Denial of Service by breaking or degrading the user interface with persistent scripts.

How can this vulnerability be detected on my network or system? Can you suggest some commands?
