Technical details
The vulnerability is a stored XSS flaw in the web page generation logic of E-Commerce Pack versions 4.5.001 through before 4.6.001, where user input is not properly neutralized before being rendered in the HTML response. An attacker can inject malicious JavaScript through input fields that are stored in the application's database and served to subsequent users, allowing arbitrary script execution in the browser context of any visitor to the affected page. No authentication is required to exploit this issue, making it a significant risk for e-commerce platforms. A patch is available in version 4.6.001 or later.
