DescriptionCVE.org

A Reflected Cross-Site Scripting (XSS) vulnerability exists in SourceCodester Inventory System 1.0 in the view_sales.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

SourceCodester Inventory System 1.0 contains a reflected cross-site scripting (XSS) vulnerability in the view_sales.php file's 'limit' parameter that allows remote attackers to inject arbitrary JavaScript or HTML through a crafted URL. The vulnerability stems from insufficient input sanitization and publicly available exploit code has been disclosed. Authentication requirements are not confirmed from available CVSS data.

Technical ContextAI

The vulnerability is a reflected XSS flaw in a PHP-based inventory management application. The 'limit' parameter in view_sales.php fails to sanitize user-supplied input before rendering it in the HTML response, allowing attackers to inject malicious script payloads that execute in the context of the victim's browser session. This is classified under the input validation and cross-site scripting category (CWE). The affected product is SourceCodester Inventory System version 1.0, a web application built in PHP. No vendor-specific CPE identifier could be definitively assigned from available data, though the vulnerability affects the application in its stated version.

RemediationAI

Upgrade SourceCodester Inventory System to the latest available version if a patched release has been issued by the vendor; however, no specific patched version number is confirmed in available data. Immediate compensating controls should include: input validation and output encoding of the 'limit' parameter and all user-supplied input in view_sales.php via HTML entity encoding; implementation of Content Security Policy (CSP) headers to restrict script execution; and enforcement of HTTPOnly and Secure flags on session cookies. Contact SourceCodester directly for patch availability and timeline. Pending vendor patching, restrict access to the application via network-level controls, Web Application Firewall rules blocking suspicious 'limit' parameter patterns, and user awareness training to avoid clicking untrusted links to the application.
