code-projects Online Shoe Store Cross-Site Scripting Vulnerability

A cross-site scripting (XSS) vulnerability has been identified in code-projects Online Shoe Store version 1.0. The issue resides in the admin_running.php file, where the product_name parameter is not properly validated or encoded before being output to users. This flaw allows attackers to inject and execute malicious scripts in the context of the user's browser, potentially leading to the theft of cookies, session tokens, or other sensitive information. The vulnerability can be exploited remotely, without the need for authentication.

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, unauthorized actions performed on behalf of the user, defacement of web pages, redirection to malicious sites, or even control over the user's browser.

Reproduction

To reproduce this vulnerability, navigate to the '/admin/admin_running.php' file and manipulate the 'product_name' parameter by injecting a script payload, such as a prompt script. This can be done by adding the payload to the parameter in a way that is not filtered or encoded by the application.

Remediation

It is recommended to implement proper output encoding for user inputs, validate and filter input data to reject malicious content, use a Content Security Policy to restrict script sources, set secure and HttpOnly flags for sensitive cookies, and conduct regular security audits.
