Overview
A critical SQL injection vulnerability, identified as CVE-2025-63532, has been discovered in the Blood Bank Management System version 1.0. This flaw resides within the `cancel.php` component and allows a remote attacker to execute arbitrary SQL commands by manipulating user-supplied input to bypass authentication mechanisms.
Technical Details
The vulnerability stems from insufficient input sanitization in the `cancel.php` file. Specifically, the application fails to properly escape or validate user-provided data used within SQL queries. An attacker can inject malicious SQL code through the search field, leading to unauthorized data access, modification, or even complete database compromise. The injection point lies within the logic handling cancellation requests, potentially affecting critical blood inventory and patient data management.
CVSS Analysis
- Severity: CRITICAL
- CVSS Score: 9.6
- CVSS Vector: (To be fully defined based on specific attack vector, but likely includes network attack vector, low attack complexity, no privileges required, high impact on confidentiality, integrity, and availability)
A CVSS score of 9.6 indicates the severity of this vulnerability is extremely high. Exploitation requires no authentication and can lead to complete system compromise. Due to the sensitive nature of the data managed by a blood bank system (patient information, blood types, donation records), a successful attack could have devastating consequences.
Possible Impact
Exploitation of this SQL injection vulnerability could have severe consequences, including:
- Authentication Bypass: Attackers can bypass login procedures and gain administrative access to the system.
- Data Breach: Sensitive patient and donor data could be accessed, exfiltrated, or modified.
- Data Manipulation: Attackers could alter blood inventory levels, potentially leading to shortages or the administration of incorrect blood types.
- System Downtime: Malicious SQL queries could disrupt the functionality of the blood bank management system, leading to service outages.
- Reputational Damage: A successful attack could severely damage the reputation of the affected blood bank.
Mitigation and Patch Steps
The following steps should be taken to mitigate the risk posed by CVE-2025-63532:
- Apply the Patch: The most effective solution is to apply the official patch released by the Blood Bank Management System vendor. Contact the vendor or check their website for updates. Unfortunately, given the references point to projects without active maintainers, a community-driven patch might be necessary.
- Input Sanitization: Implement robust input sanitization and validation techniques throughout the application, especially in `cancel.php`. Use parameterized queries or prepared statements to prevent SQL injection.
- Web Application Firewall (WAF): Deploy a WAF to detect and block malicious SQL injection attempts. Configure the WAF with rules specific to this vulnerability.
- Least Privilege Principle: Ensure that database users have only the necessary privileges required to perform their tasks. Avoid using the ‘root’ or ‘administrator’ account for routine operations.
- Regular Security Audits: Conduct regular security audits and penetration testing to identify and address vulnerabilities in your systems.
