CVE-2025-63534 is a high-severity cross-site scripting (XSS) vulnerability in the Blood Bank Management System 1.0, specifically in the login.php component. The vulnerability arises because user inputs in the 'msg' and 'error' parameters are not properly sanitized or encoded before being rendered, allowing attackers to inject malicious JavaScript. This can lead to execution of arbitrary scripts in the victim's browser without requiring user interaction or authentication. The vulnerability has a CVSS score of 8.5, indicating a critical impact on confidentiality and a partial impact on integrity. Although no known exploits are currently in the wild, exploitation could result in session hijacking, data theft, or unauthorized actions within the application. European healthcare organizations using this system are at risk, especially those with critical blood bank infrastructure. Mitigation requires immediate input validation and output encoding, alongside monitoring and restricting access to vulnerable components.

A session fixation vulnerability exists in Blood Bank Management System 1.0 in login.php that allows an attacker to set or predict a user's session identifier prior to authentication. When the victim logs in, the application continues to use the attacker-supplied session ID rather than generating a new one, enabling the attacker to hijack the authenticated session and gain unauthorized access to the victim's account.
