CVE-2025-3307: Blood Bank Management System SQLi Flaw

CVE-2025-3307 Overview

A SQL injection vulnerability has been identified in Code-Projects Blood Bank Management System version 1.0. The vulnerability exists in the /reset.php file, where the useremail parameter is improperly validated before being used in database queries. This flaw allows unauthenticated remote attackers to inject malicious SQL statements, potentially compromising the confidentiality, integrity, and availability of the underlying database.

Critical Impact
This SQL injection vulnerability enables unauthorized database access, allowing attackers to extract sensitive medical and donor information, modify records, or disrupt system availability through remote exploitation without authentication.

Technical Details for CVE-2025-3307

Vulnerability Analysis

This SQL injection vulnerability affects the password reset functionality within the Blood Bank Management System. The application fails to properly sanitize or parameterize user-supplied input in the useremail parameter of the /reset.php file before incorporating it into SQL queries. This allows attackers to manipulate the query structure and execute arbitrary SQL commands against the backend database.

The vulnerability is particularly concerning in a healthcare-related application, as Blood Bank Management Systems typically store sensitive personally identifiable information (PII), medical records, and donor data. Successful exploitation could lead to unauthorized access to confidential health information, data manipulation, or complete database compromise.

Root Cause

The root cause of this vulnerability is improper input validation and the lack of parameterized queries (prepared statements) in the /reset.php file. When user input from the useremail parameter is directly concatenated into SQL queries without proper sanitization, it creates an injection point that attackers can exploit to modify the intended query logic.

Attack Vector

The attack can be executed remotely over the network without requiring any authentication or user interaction. An attacker can craft malicious HTTP requests to the /reset.php endpoint with SQL injection payloads in the useremail parameter.

The vulnerability allows an attacker to submit specially crafted input through the password reset form that alters the structure of the underlying SQL query. By injecting SQL metacharacters and statements into the useremail parameter, attackers can bypass authentication logic, extract database contents, modify or delete records, and potentially execute administrative operations on the database server.

For example, an attacker could submit input containing SQL syntax that causes the application to return all user records, bypass password reset verification, or enumerate database schema information. For detailed technical analysis, refer to the GitHub CVE Issue Discussion.

Detection Methods for CVE-2025-3307

Indicators of Compromise

Unusual or malformed requests to /reset.php containing SQL metacharacters such as single quotes, double dashes, UNION statements, or semicolons
Database error messages in application logs indicating syntax errors or unexpected query behavior
Abnormal database query patterns or response times from the Blood Bank Management System
Evidence of data exfiltration or unauthorized database access in audit logs

Detection Strategies

Implement Web Application Firewall (WAF) rules to detect and block SQL injection patterns targeting the /reset.php endpoint
Deploy intrusion detection systems (IDS) with signatures for common SQL injection attack patterns
Enable verbose logging on the web server and database to capture suspicious query activity
Monitor for anomalous HTTP POST requests to the password reset functionality

Monitoring Recommendations

Review web server access logs for requests to /reset.php with suspicious parameter values
Enable database query logging and monitor for UNION-based, error-based, or time-based SQL injection techniques
Set up alerts for multiple failed password reset attempts or unusual patterns of access to the reset functionality
Conduct regular security assessments and penetration testing focusing on input validation controls

How to Mitigate CVE-2025-3307

Immediate Actions Required

Restrict or disable access to the /reset.php endpoint until a patch is applied
Implement input validation and sanitization for the useremail parameter at the web application firewall or application layer
Enable SQL query logging to detect any ongoing exploitation attempts
Review database access logs for signs of unauthorized access or data exfiltration

Patch Information

No official vendor patch has been released at this time. Organizations using Code-Projects Blood Bank Management System 1.0 should monitor the Code Projects Security Hub for updates and patch availability. For additional vulnerability details, refer to VulDB #303504.

Workarounds

Implement prepared statements and parameterized queries in the /reset.php file to prevent SQL injection
Deploy a Web Application Firewall (WAF) with SQL injection detection rules to filter malicious requests
Restrict network access to the Blood Bank Management System to trusted IP addresses only
Apply the principle of least privilege to database accounts used by the application to limit potential damage from exploitation
