File Management System 1.1 – Persistent Cross-Site Scripting

A persistent cross-site scripting vulnerability exists in File Management System 1.1. An attacker can inject malicious JavaScript code into the 'name' parameter of the 'view_admin.php' page, which will be executed when the page is viewed. This can be exploited to execute arbitrary HTML and script code in a user's browser session in context of an affected site.

Mitigation:

Input validation should be used to prevent the injection of malicious code into the application. All user-supplied input should be validated and filtered before being used in the application.

2. Add admin click button

3. We write payload in the name section (<script>alert(1);</script>)

4. And view admin click button

5. And our bad payload will be displayed
