A Reflected Cross-Site Scripting (XSS) vulnerability exists in SourceCodester Sales and Inventory System 1.0. The vulnerability is located in the view_supplier.php file via the "limit" parameter. The application fails to sanitize the input, allowing remote attackers to inject arbitrary web script or HTML via a crafted URL.
AnalysisAI
Reflected Cross-Site Scripting (XSS) in SourceCodester Sales and Inventory System 1.0 allows remote attackers to inject arbitrary JavaScript or HTML through the 'limit' parameter in view_supplier.php due to insufficient input sanitization. The vulnerability is accessible without authentication via crafted URLs, and publicly available exploit code exists demonstrating the attack vector.
Technical ContextAI
The vulnerability is a Reflected XSS (CWE-79: Improper Neutralization of Input During Web Page Generation) affecting a PHP-based inventory management application. The view_supplier.php file processes the 'limit' parameter without proper encoding or validation, allowing attacker-controlled input to be reflected directly in HTTP responses. When a victim visits a malicious URL containing JavaScript payload in the limit parameter, the application executes the injected script in the victim's browser context, potentially compromising session cookies, credentials, or performing unauthorized actions on behalf of the user.
RemediationAI
Immediate remediation requires upgrading to a patched version of SourceCodester Sales and Inventory System if available from the vendor; however, no specific patched version number was identified in available data. As a primary mitigation, implement input validation and output encoding for the 'limit' parameter in view_supplier.php by using parameterized queries and HTML entity encoding (e.g., htmlspecialchars() in PHP) for all user-supplied input reflected in responses. Implement Content Security Policy (CSP) headers to restrict inline script execution. If the vendor has not released a patch, disable or restrict access to the inventory system until patching is confirmed, or apply Web Application Firewall rules to block requests with script payloads in the limit parameter.
