CVE-2025-63531 identifies a critical SQL injection vulnerability in the Blood Bank Management System version 1.0, specifically within the receiverLogin.php component. The vulnerability arises because the application fails to properly sanitize user inputs in the remail and rpassword fields before incorporating them into SQL queries. This improper input handling allows an attacker to inject arbitrary SQL commands, effectively bypassing authentication mechanisms without needing any prior privileges or user interaction. The vulnerability is remotely exploitable over the network, as no authentication is required to trigger the flaw. The CVSS v3.1 score of 10.0 reflects the highest severity, indicating complete compromise of confidentiality, integrity, and availability with a scope change, meaning the attack can affect resources beyond the initially vulnerable component. Although no public exploits are currently known, the vulnerability's nature and ease of exploitation make it a critical threat. The CWE-89 classification confirms it as a classic SQL injection issue, which can lead to unauthorized data access, data manipulation, or even full system compromise. The lack of available patches necessitates immediate attention from organizations using this system to prevent potential breaches.

For European organizations, especially those in the healthcare sector using the Blood Bank Management System 1.0, this vulnerability poses a severe risk. Exploitation can lead to unauthorized access to sensitive patient data, including blood donation records and personal health information, violating GDPR and other data protection regulations. The integrity of the system can be compromised, allowing attackers to alter or delete critical data, potentially disrupting blood bank operations and patient care. Availability may also be impacted if attackers execute destructive SQL commands or leverage the access to deploy ransomware or other malware. The reputational damage and regulatory penalties following a breach could be substantial. Given the critical nature of healthcare infrastructure, such an attack could also have broader public health implications. The vulnerability’s remote and unauthenticated exploitability increases the attack surface, making it a prime target for cybercriminals and potentially nation-state actors interested in healthcare data.

Immediate mitigation steps include conducting a thorough code audit of the receiverLogin.php component and all SQL query constructions to identify and remediate unsafe input handling. Developers should implement parameterized queries or prepared statements to prevent SQL injection. Input validation and sanitization should be enforced on all user-supplied data, particularly the remail and rpassword fields. Organizations should monitor logs for unusual login attempts or SQL errors indicative of exploitation attempts. Network-level protections such as web application firewalls (WAFs) can provide temporary defense by blocking suspicious payloads targeting SQL injection. Given the absence of official patches, organizations should consider isolating or restricting access to the vulnerable system until remediation is complete. Regular backups and incident response plans should be updated to prepare for potential exploitation. Finally, organizations should engage with vendors or developers for official patches and updates as soon as they become available.
