CVE-2024-51225: Phpgurukul Vehicle Record XSS Vulnerability

CVE-2024-51225 Overview

A stored cross-site scripting (XSS) vulnerability has been identified in Phpgurukul Vehicle Record Management System v1.0. The vulnerability exists in the /admin/add-brand.php component, where insufficient input validation allows attackers with administrative privileges to inject malicious JavaScript or HTML code through the brandname parameter. When other users access the affected page, the injected payload executes in their browser context, potentially leading to session hijacking, data theft, or further malicious actions.

Critical Impact

Authenticated attackers can inject persistent malicious scripts that execute in other users' browsers, enabling session theft, credential harvesting, and administrative account takeover.

Technical Details for CVE-2024-51225

Vulnerability Analysis

This stored XSS vulnerability (CWE-79) affects the brand management functionality within the administrative panel of the Vehicle Record Management System. The application fails to properly sanitize user-supplied input in the brandname parameter before storing it in the database and subsequently rendering it in web pages.

When an administrator adds a new vehicle brand through the /admin/add-brand.php endpoint, the application accepts the brand name without adequate validation or output encoding. The malicious payload is then stored persistently in the application's database. Each time this data is retrieved and displayed to users—including other administrators—the injected script executes within their browser session.

The attack requires administrative privileges to inject the payload, but the impact extends to all users who view the affected content. This makes it particularly dangerous in multi-administrator environments where one compromised or malicious admin account can affect others.

Root Cause

The root cause of this vulnerability is improper input validation and output encoding in the /admin/add-brand.php component. The application directly accepts and stores user input from the brandname parameter without sanitizing special HTML characters or implementing context-aware output encoding when rendering the stored data. This allows script tags and event handlers to be preserved and executed when the content is displayed.

Attack Vector

The attack is conducted over the network and requires an authenticated user with administrative privileges. The attacker navigates to the add-brand functionality and submits a crafted payload containing malicious JavaScript within the brandname field. Example payloads could include embedded <script> tags or event handler attributes such as onload, onerror, or onmouseover attached to HTML elements.

Once stored, the payload persists in the database and executes automatically when any user accesses pages that display brand information. The attacker can leverage this to steal session cookies, redirect users to phishing sites, modify page content, or perform actions on behalf of the victim user.

Detection Methods for CVE-2024-51225

Indicators of Compromise

• Unusual brand names containing HTML tags such as <script>, <img>, <svg>, or <iframe> in the database
• Brand entries with JavaScript event handlers like onerror, onload, onclick, or onmouseover
• Unexpected outbound connections from admin user browsers to unfamiliar external domains
• Reports of unusual browser behavior or pop-ups when accessing brand management pages

Detection Strategies

• Implement web application firewall (WAF) rules to detect and block XSS payloads in form submissions targeting /admin/add-brand.php
• Monitor application logs for form submissions containing HTML tags or JavaScript syntax in the brandname parameter
• Deploy browser-based security tools or Content Security Policy (CSP) headers to detect and report inline script execution
• Conduct periodic database audits to identify stored entries containing potential XSS payloads

Monitoring Recommendations

• Enable verbose logging for all administrative actions, particularly those involving data input and modification
• Configure alerts for any database insertions containing characters commonly associated with XSS attacks (e.g., <, >, ", ')
• Monitor for unusual session activity that might indicate session hijacking resulting from XSS exploitation
• Review access logs for repeated access to brand-related pages that could indicate testing or exploitation attempts

How to Mitigate CVE-2024-51225

Immediate Actions Required

• Audit the database for any brand entries containing suspicious HTML or JavaScript content and remove malicious entries
• Restrict access to the Vehicle Record Management System administrative panel to trusted personnel only
• Consider temporarily disabling the add-brand functionality until a patch or fix is implemented
• Implement a Content Security Policy (CSP) header to mitigate the impact of any stored XSS payloads

Patch Information

As of the last NVD update on 2026-03-24, no official patch has been released by the vendor. Organizations using Phpgurukul Vehicle Record Management System v1.0 should monitor the GitHub Vulnerability Research Repository for updates and consider implementing the workarounds listed below.

Workarounds

• Apply input validation to the brandname parameter, rejecting any input containing HTML tags or JavaScript syntax
• Implement output encoding using PHP's htmlspecialchars() or htmlentities() functions when displaying brand names
• Add a strict Content Security Policy (CSP) header that disables inline script execution: Content-Security-Policy: script-src 'self'
• Consider using a PHP security library or framework that provides automatic XSS protection for user-generated content

# Example Apache .htaccess CSP configuration
Header set Content-Security-Policy "default-src 'self'; script-src 'self'; style-src 'self' 'unsafe-inline'"
