Overview
A critical SQL injection vulnerability, identified as CVE-2025-63535, has been discovered in the Blood Bank Management System version 1.0. This flaw resides within the abs.php component of the application. Due to inadequate input sanitization, attackers can inject arbitrary SQL code into queries, potentially leading to unauthorized data access, modification, or even complete system compromise.
Technical Details
The vulnerability stems from the application’s failure to properly sanitize user-supplied input within SQL queries executed by abs.php. Specifically, the search functionality is vulnerable. An attacker can manipulate the search field to inject malicious SQL code. This injected code is then interpreted and executed by the database, bypassing authentication mechanisms and granting the attacker unauthorized access to sensitive data or administrative privileges.
Successful exploitation allows an attacker to:
- Bypass authentication.
- Read sensitive data (e.g., donor information, blood inventory).
- Modify data (e.g., change blood types, delete records).
- Potentially execute arbitrary commands on the database server (depending on database configuration and permissions).
CVSS Analysis
This vulnerability has been assigned a CVSS score of 9.6 (Critical), highlighting the severity and potential impact. The high score reflects the ease of exploitation, the low skill level required, and the significant consequences of a successful attack.
Possible Impact
The impact of exploiting this vulnerability is significant and includes:
- Data Breach: Exposure of sensitive patient and donor information.
- Data Manipulation: Modification of blood inventory data, potentially leading to incorrect blood transfusions.
- System Compromise: Complete takeover of the Blood Bank Management System.
- Reputational Damage: Loss of trust in the organization due to security breaches.
- Legal and Regulatory Implications: Potential fines and penalties for failing to protect sensitive data.
Mitigation and Patch Steps
To mitigate this vulnerability, the following steps are recommended:
- Immediate Patching: Apply the latest patch or upgrade to a secure version of the Blood Bank Management System as soon as it becomes available from the vendor. Contact the original developer, Shridharshukl, if a patch is unavailable.
- Input Sanitization: Implement robust input sanitization and validation techniques to prevent SQL injection attacks. Use parameterized queries or prepared statements to ensure that user-supplied data is treated as data, not as executable code.
- Web Application Firewall (WAF): Deploy a web application firewall (WAF) to detect and block malicious requests, including SQL injection attempts.
- Least Privilege Principle: Ensure that the database user account used by the application has only the necessary privileges to perform its functions. Avoid granting excessive permissions.
- Regular Security Audits: Conduct regular security audits and penetration testing to identify and address vulnerabilities in the system.
