A Reflected Cross-Site Scripting (XSS) vulnerability exists in SourceCodester Sales and Inventory System 1.0. The vulnerability is located in the view_customers.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 in SourceCodester Sales and Inventory System 1.0 allows remote attackers to inject arbitrary JavaScript or HTML via the unvalidated "limit" parameter in view_customers.php, affecting unauthenticated users who click malicious links. Publicly available exploit code exists demonstrating the vulnerability, though no CVSS score is available to quantify severity.
Technical ContextAI
The vulnerability stems from insufficient input validation in a PHP-based web application. The view_customers.php endpoint accepts a "limit" parameter that is reflected in the HTTP response without proper encoding or sanitization, creating a reflected XSS vector. Attackers craft URLs embedding malicious JavaScript payloads that execute in the victim's browser when the page is rendered, operating within the context of the application domain. This allows session hijacking, credential theft, or unauthorized actions performed as the victim user.
RemediationAI
Apply input validation and output encoding to the "limit" parameter in view_customers.php. Implement server-side filtering to accept only numeric values for the limit parameter and reject or sanitize any non-numeric input. Additionally, use context-aware output encoding (HTML entity encoding) when displaying user-controlled data in the response. The vendor should release a patched version addressing input validation; users should upgrade immediately upon availability. Pending a vendor patch, web application firewalls or reverse proxies can block requests containing script tags or encoded payloads in the limit parameter.
