The CVE-2025-63534 vulnerability is a Reflected Cross-Site Scripting (XSS) flaw within the `login.php` component of Blood Bank Management System version 1.0. The application fails to perform adequate input validation, sanitization, or output encoding on user-controllable parameters. Specifically, the `msg` and `error` parameters in HTTP GET requests are directly echoed into the application’s HTML response without proper neutralization. An attacker can craft a malicious URL containing a JavaScript payload within these parameters. When an unsuspecting victim, such as an administrator, is tricked into clicking the crafted link, the embedded script executes within their browser session in the context of the vulnerable application. This allows the attacker to steal session cookies, perform actions on behalf of the user, or deface the application.
