Code-Projects Chamber of Commerce Membership Management System Cross-Site Scripting Vulnerability

A cross-site scripting (XSS) vulnerability has been identified in version 1.0 of the Code-Projects Chamber of Commerce Membership Management System. The issue resides in the 'Your Info Handler' component, specifically within the '/membership_profile.php' file. The vulnerability allows for the injection of malicious scripts by manipulating the 'Full Name/Address/City/State' fields. This flaw can be exploited remotely and requires user interaction.

Impact

Exploitation of this vulnerability allows for reflective cross-site scripting, where an attacker can inject and execute arbitrary scripts in the context of the user's browser.

Reproduction

To reproduce this vulnerability, log into the application and navigate to the '/membership_profile.php' page. Modify the 'Full Name/Address/City/State' fields to include malicious JavaScript or HTML. After updating the profile, the injected script will execute when the profile is viewed by another user or an administrator.

Remediation

It is recommended to escape all user-generated output using HTML entities to prevent the execution of HTML or JavaScript. Input sanitization should also be applied to filter out harmful code before it is processed.
