CVE-2025-50487 is a security vulnerability identified in the PHPGurukul Blood Bank & Donor Management System version 2.4, specifically within the /bbdms/change-password.php component. The vulnerability arises from improper session invalidation, which means that when a user changes their password, the system fails to correctly terminate or invalidate the existing session tokens associated with that user. This flaw enables an attacker to hijack an active session, potentially gaining unauthorized access to the victim's account without needing to re-authenticate. Session hijacking exploits weaknesses in session management, allowing attackers to impersonate legitimate users and perform actions on their behalf. Since this vulnerability is located in a critical function related to user authentication and account management, it poses a significant risk to the confidentiality and integrity of user data. The absence of a CVSS score indicates that the vulnerability is newly published and has not yet been fully assessed or exploited in the wild. However, the technical nature of improper session invalidation is well-understood and commonly exploited in web applications, making this a serious concern. The vulnerability does not specify affected versions beyond v2.4, and no patches or known exploits are currently documented. The system in question is a specialized healthcare management platform, which likely handles sensitive personal and medical data, increasing the stakes of any unauthorized access.

For European organizations, particularly healthcare providers and blood bank management entities using PHPGurukul Blood Bank & Donor Management System v2.4, this vulnerability could lead to unauthorized access to sensitive patient and donor information. Such a breach could compromise personal health data, violating GDPR regulations and resulting in significant legal and financial penalties. Additionally, session hijacking could allow attackers to manipulate donor records, disrupt blood supply chain management, or perform fraudulent activities under legitimate user identities. The impact extends beyond data confidentiality to potential operational disruptions in critical healthcare services. Given the sensitive nature of healthcare data and the strict regulatory environment in Europe, exploitation of this vulnerability could severely damage organizational reputation and trust. Moreover, healthcare systems are often targeted by cybercriminals and nation-state actors, increasing the likelihood of targeted attacks exploiting this flaw.

Organizations should immediately review and update their session management practices within the PHPGurukul Blood Bank & Donor Management System. Specific mitigations include: 1) Implementing proper session invalidation upon password changes, ensuring all active sessions for the user are terminated and new sessions require re-authentication. 2) Enforcing secure, HttpOnly, and SameSite cookie attributes to reduce session token theft via cross-site scripting or cross-site request forgery. 3) Applying multi-factor authentication (MFA) to add an additional layer of security beyond session tokens. 4) Monitoring and logging session activities to detect anomalies indicative of session hijacking attempts. 5) Conducting a thorough code review and penetration testing focused on session management components. 6) If available, applying vendor patches or updates addressing this vulnerability as soon as they are released. 7) Educating users about the importance of logging out after sessions and recognizing suspicious account activities. These measures should be prioritized given the sensitivity of the data involved and the potential for regulatory non-compliance.
