CVE-2025-63529 in Blood Bank Management System
Summary
by MITRE • 12/01/2025
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.

The session fixation vulnerability in Blood Bank Management System 1.0 represents a critical security flaw that undermines the fundamental authentication mechanisms of the application. This vulnerability resides within the login.php component and allows malicious actors to manipulate session identifiers before user authentication occurs. The flaw stems from the application's failure to properly regenerate session identifiers upon successful authentication, creating an exploitable condition where attackers can predict or set session tokens that persist beyond the initial login process.
The technical implementation of this vulnerability aligns with CWE-384, which specifically addresses session fixation issues in web applications. When an attacker successfully establishes a session with the system, they can manipulate the session identifier to a known value and then wait for a legitimate user to authenticate. The application continues to utilize the attacker-controlled session ID rather than generating a fresh identifier, effectively allowing the attacker to hijack the authenticated session. This flaw operates at the intersection of application-level security and session management protocols, creating a persistent threat vector that can be exploited across multiple user sessions.
The operational impact of this vulnerability extends beyond simple unauthorized access, creating a comprehensive threat landscape for blood bank management systems that handle sensitive medical data. An attacker who successfully exploits this vulnerability can gain complete control over user accounts, potentially accessing confidential patient information, blood inventory records, and administrative functions. The implications are particularly severe in healthcare environments where data integrity and patient privacy are paramount, as this vulnerability could enable unauthorized modifications to critical medical records or complete system compromise.
Security professionals should implement immediate mitigations including mandatory session regeneration upon successful authentication, which directly addresses the root cause of this vulnerability. The system must be configured to generate new session identifiers with sufficient entropy and ensure that old session tokens are invalidated upon user login. Additionally, implementing proper session management practices including secure cookie attributes, session timeout mechanisms, and regular session validation checks would significantly reduce the attack surface. Organizations should also consider implementing additional layers of authentication such as multi-factor authentication to provide defense-in-depth against session hijacking attempts. The vulnerability demonstrates the critical importance of following secure coding practices and adhering to established security frameworks that prevent session management flaws from compromising system integrity and user confidentiality.
