Overview
A critical security vulnerability, identified as CVE-2025-63531, has been discovered in the Blood Bank Management System version 1.0. This vulnerability is a SQL injection flaw located within the receiverLogin.php component. This allows attackers to potentially bypass authentication and gain unauthorized access to sensitive data within the system.
Technical Details
The vulnerability arises because the application fails to properly sanitize user-supplied input within SQL queries. Specifically, the remail and rpassword fields in receiverLogin.php are vulnerable to SQL injection. An attacker can craft malicious SQL code within these fields, which, when processed by the application, can allow them to:
- Bypass authentication mechanisms.
- Read, modify, or delete sensitive data within the database.
- Potentially execute arbitrary code on the server (depending on database configuration and permissions).
The lack of input validation and proper escaping makes the application highly susceptible to this type of attack.
CVSS Analysis
- CVE ID: CVE-2025-63531
- Severity: CRITICAL
- CVSS Score: 10.0
A CVSS score of 10.0 indicates the highest level of severity. This means the vulnerability is easily exploitable, requires no user interaction, and has a significant impact on confidentiality, integrity, and availability of the system.
Possible Impact
The exploitation of this SQL injection vulnerability can have severe consequences:
- Data Breach: Unauthorized access to sensitive blood donor and recipient information, including personal details, medical history, and contact information.
- System Compromise: Complete control over the Blood Bank Management System, potentially leading to data manipulation, service disruption, or further attacks on connected systems.
- Reputational Damage: Loss of trust and credibility for the organization responsible for the blood bank management system.
- Legal and Regulatory Consequences: Potential fines and penalties for failing to protect sensitive data, especially if regulations like HIPAA or GDPR are applicable.
Mitigation or Patch Steps
To mitigate this critical vulnerability, the following steps should be taken immediately:
- Input Validation and Sanitization: Implement robust input validation and sanitization techniques for all user-supplied data, especially in SQL queries. Use parameterized queries or prepared statements to prevent SQL injection.
- Apply Patch (If Available): Check if the vendor has released a patch or update that addresses this vulnerability. Apply the patch immediately to fix the vulnerable code.
- Web Application Firewall (WAF): Deploy a Web Application Firewall (WAF) to filter out malicious requests and block SQL injection attempts. Configure the WAF with appropriate rules to detect and prevent exploitation.
- Least Privilege Principle: Ensure that the database user account used by the application has only the necessary permissions to perform its functions. Avoid using privileged accounts that could be exploited for wider system access.
- Security Audits and Penetration Testing: Conduct regular security audits and penetration testing to identify and address potential vulnerabilities in the system.
