Campcodes Sales and Inventory System Cross-Site Scripting Vulnerability

A cross-site scripting (XSS) vulnerability has been identified in Campcodes Sales and Inventory System version 1.0. The issue arises in the file '/index.php' when the 'page' parameter is manipulated. This vulnerability allows remote attackers to inject and execute malicious scripts in the context of the user's browser. The lack of proper input validation and output encoding for the 'page' parameter enables this exploitation, potentially leading to the theft of cookies, session tokens, or other sensitive information from the victim.

Impact

Exploitation of this vulnerability allows for cross-site scripting, where injected scripts are executed in the context of the user's browser. This could lead to the theft of cookies or session tokens, defacement of web pages, redirection of users to malicious sites, or unauthorized actions performed on behalf of the user.

Reproduction

To reproduce this vulnerability, navigate to the 'index.php' file of the Campcodes Sales and Inventory System version 1.0. Append the 'page' parameter with a script payload, such as a JavaScript alert. The injected script will execute in the browser, demonstrating the cross-site scripting vulnerability.

Remediation

It is recommended to implement proper input validation and output encoding for user-controlled parameters. Additionally, a Content Security Policy (CSP) should be established to restrict the execution of scripts. For sensitive cookies, set the HttpOnly and Secure flags to enhance protection.
