CVE-2025-3310: Blood Bank Management System SQLi Flaw

CVE-2025-3310 Overview

A SQL injection vulnerability has been identified in the code-projects Blood Bank Management System version 1.0. This vulnerability exists in the /admin/delete.php file, where improper handling of the Search argument allows attackers to inject malicious SQL queries. The vulnerability can be exploited remotely without authentication, potentially allowing unauthorized access to sensitive database information, data manipulation, or complete system compromise.

Critical Impact
Remote attackers can exploit this SQL injection flaw to access, modify, or delete sensitive blood bank records, donor information, and administrative data without authentication.

Technical Details for CVE-2025-3310

Vulnerability Analysis

This SQL injection vulnerability affects the administrative deletion functionality of the Blood Bank Management System. The flaw resides in /admin/delete.php, where the application fails to properly sanitize user-supplied input in the Search parameter before incorporating it into SQL queries. This classic injection vulnerability allows attackers to manipulate database queries by injecting malicious SQL statements through the vulnerable parameter.

The vulnerability is classified under CWE-74 (Improper Neutralization of Special Elements in Output Used by a Downstream Component), commonly known as Injection. When user input is directly concatenated into SQL queries without proper parameterization or escaping, attackers can break out of the intended query structure and execute arbitrary SQL commands.

Root Cause

The root cause of this vulnerability is the lack of input validation and parameterized queries in the /admin/delete.php file. The application directly incorporates user-controlled input from the Search argument into SQL queries without sanitization. This allows special characters and SQL syntax to be interpreted as part of the query structure rather than as literal data values.

Attack Vector

The attack can be initiated remotely over the network without requiring any authentication or user interaction. An attacker can craft malicious HTTP requests containing SQL injection payloads in the Search parameter. When the vulnerable endpoint processes these requests, the injected SQL commands are executed against the backend database.

The exploitation typically involves manipulating the Search parameter in requests to /admin/delete.php. Attackers can use techniques such as UNION-based injection to extract data, boolean-based blind injection to enumerate database contents, or stacked queries to perform data modification or deletion operations.

Detection Methods for CVE-2025-3310

Indicators of Compromise

Unusual or malformed requests to /admin/delete.php containing SQL syntax characters such as single quotes, double dashes, or UNION keywords
Database error messages in application logs indicating syntax errors or failed queries
Unexpected data access patterns or bulk data extraction from the blood bank database
Unauthorized modifications to donor records, blood inventory, or administrative accounts

Detection Strategies

Implement web application firewall (WAF) rules to detect SQL injection patterns in requests to /admin/delete.php
Monitor application logs for SQL error messages that may indicate injection attempts
Deploy intrusion detection systems (IDS) with signatures for common SQL injection attack patterns
Analyze database query logs for anomalous query structures or unauthorized data access

Monitoring Recommendations

Enable detailed logging for the /admin/ directory and monitor for suspicious parameter values
Set up alerts for database queries containing injection-related keywords from web application contexts
Implement database activity monitoring to track unusual SELECT, UPDATE, or DELETE operations on sensitive tables
Review access logs for repeated requests to the delete.php endpoint with varying parameter values

How to Mitigate CVE-2025-3310

Immediate Actions Required

Restrict network access to the /admin/delete.php endpoint using IP whitelisting or VPN requirements
Implement input validation to reject requests containing SQL metacharacters in the Search parameter
Deploy a web application firewall with SQL injection protection rules
Consider temporarily disabling the vulnerable endpoint until a patch is available
Audit database logs to identify any potential exploitation that may have already occurred

Patch Information

No official vendor patch has been identified for this vulnerability at the time of publication. Organizations using the affected Blood Bank Management System should contact Code Projects for remediation guidance. Consider implementing the workarounds below until an official fix is released.

Workarounds

Implement prepared statements or parameterized queries to prevent SQL injection in the affected code
Add server-side input validation to sanitize all user-supplied input before database operations
Use a web application firewall to filter malicious requests targeting the vulnerable endpoint
Apply the principle of least privilege to database accounts used by the application
Consider migrating to a more actively maintained blood bank management solution
