Executive Summary

This is a stored Cross-Site Scripting (XSS) vulnerability in the Inventory Management System 1.0. It allows attackers to inject malicious JavaScript into vendor input fields like Vendor Name or Address. The injected scripts are stored in the database and executed when users view the Vendor Management page, potentially enabling session hijacking or account takeover.

Detection Guidance

To detect this XSS vulnerability, inspect the Vendor Management module in Inventory Management System for unsanitized input fields like Vendor Name, Mobile, PAN Number, GST Number, and Address. Check if malicious scripts are stored in the database or rendered in /vendors.php. Review /api/vendors_handler.php for improper input handling.

Impact Analysis

An attacker could steal session cookies, hijack accounts, or take over accounts entirely. This includes administrators, leading to full system compromise. The attack requires authentication but can be carried out by any authenticated user with vendor management access.

Compliance Impact

This vulnerability could lead to unauthorized access to sensitive data, violating GDPR's data protection requirements and HIPAA's security rules for protected health information. It may result in data breaches, non-compliance penalties, and loss of trust.

Mitigation Strategies

Apply htmlspecialchars() to all vendor fields before rendering. Implement server-side input validation to reject HTML/JavaScript content. Apply Content Security Policy (CSP) headers. Sanitize all fields in vendors_handler.php on both input and output. Ensure only trusted users can add vendors.
