Campcodes Grocery Sales and Inventory System Cross-Site Scripting Vulnerability

A cross-site scripting (XSS) vulnerability has been identified in Campcodes Grocery 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, and 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, allowing attackers to impersonate users or access sensitive information.

Reproduction

To reproduce this vulnerability, navigate to the 'index.php' file of the Campcodes Grocery Sales and Inventory System. 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

Users are advised to encode output properly, validate and filter input, implement a Content Security Policy, set secure and HttpOnly flags for cookies, and conduct regular security audits.
