SourceCodester Yoga Class Registration System list.php cross site scripting
url：admin/user/list.PHP

Abstract:

Line 56 of list.php sends unvalidated data to a WEB browser, which can result in the browser executing malicious code.

Explanation:

Cross-site scripting (XSS) vulnerabilities occur when:

1. Data enters a web application through an untrusted source. In the case of persistent (also known as stored) XSS, the untrusted source is typically a database or other back-end data store, while in the case of reflected XSS it is typically a web request.

In this case, the data enters at query() in list.php at line 48.

2. The data is included in dynamic content that is sent to a web user without being validated.

In this case, the data is sent at builtin_echo() in list.php at line 56.

It is clear that the application doesn’t perfORM data validation and trust user-supplied data, we can use the below XSS payload as input which may be stored in the application.
