CVE-2025-3308 Overview
A SQL Injection vulnerability has been identified in the Blood Bank Management System version 1.0, developed by code-projects. This vulnerability affects the /viewrequest.php file, where improper handling of the ID parameter allows attackers to inject malicious SQL queries. The attack can be launched remotely without authentication, potentially compromising the confidentiality, integrity, and availability of the underlying database.
Critical Impact
Unauthenticated attackers can exploit this SQL injection flaw to extract sensitive data, modify database records, or potentially gain unauthorized access to the blood bank management system.

Technical Details for CVE-2025-3308
Vulnerability Analysis
This SQL Injection vulnerability exists due to insufficient input validation in the viewrequest.php file. The ID parameter is directly incorporated into SQL queries without proper sanitization or parameterized query implementation. This classic injection flaw allows attackers to manipulate database queries by crafting malicious input that alters the intended SQL command structure.
The vulnerability is classified under CWE-89 (Improper Neutralization of Special Elements used in an SQL Command) and CWE-74 (Improper Neutralization of Special Elements in Output Used by a Downstream Component). These weaknesses indicate that the application fails to properly neutralize user-supplied input before using it in SQL statements.
Root Cause
The root cause of this vulnerability is the lack of proper input validation and sanitization for the ID parameter in the /viewrequest.php file. The application directly concatenates user input into SQL queries rather than using prepared statements or parameterized queries. This allows specially crafted input containing SQL metacharacters to modify the query logic.
Attack Vector
The attack vector is network-based, requiring no authentication or user interaction. An attacker can exploit this vulnerability remotely by sending crafted HTTP requests to the /viewrequest.php endpoint with a malicious ID parameter value. The exploit has been publicly disclosed, increasing the risk of exploitation in the wild.
Typical SQL injection payloads targeting this vulnerability would manipulate the ID parameter to:
- Extract sensitive information from the database using UNION-based injection
- Bypass authentication mechanisms
- Modify or delete database records
- Enumerate database schema and table structures
For technical details on the exploitation methodology, refer to the GitHub CVE Issue Report or VulDB #303505.
Detection Methods for CVE-2025-3308
Indicators of Compromise
- Unusual or malformed requests to /viewrequest.php containing SQL metacharacters such as single quotes, double dashes, or UNION keywords in the ID parameter
- Web server logs showing requests with URL-encoded SQL injection patterns targeting the viewrequest endpoint
- Database error messages or anomalies in application logs indicating failed SQL parsing
- Unexpected database queries or data extraction activities in database audit logs
Detection Strategies
- Deploy Web Application Firewall (WAF) rules to detect and block SQL injection attempts targeting the ID parameter
- Implement application-level logging to monitor all requests to /viewrequest.php for suspicious patterns
- Enable database query logging to identify anomalous or unauthorized SQL statements
- Use intrusion detection systems (IDS) with signatures for common SQL injection attack patterns
Monitoring Recommendations
- Monitor web server access logs for requests containing SQL injection indicators such as ', --, UNION, SELECT, or OR 1=1
- Set up alerts for abnormal database activity including bulk data retrieval or schema enumeration queries
- Review authentication logs for any bypass attempts correlated with viewrequest.php access
- Implement real-time monitoring for database connections from unexpected sources
How to Mitigate CVE-2025-3308
Immediate Actions Required
- Restrict network access to the Blood Bank Management System to trusted IP addresses only
- Consider temporarily disabling or restricting access to the /viewrequest.php endpoint until a fix is applied
- Implement input validation at the web server or WAF level to filter malicious ID parameter values
- Review and audit database access logs for any signs of prior exploitation
- Back up the database and prepare incident response procedures
Patch Information
At the time of publication, no official patch from the vendor has been identified. System administrators should monitor Code Projects for security updates. In the absence of an official patch, implementing the workarounds below is strongly recommended.
For additional technical details and vulnerability tracking, refer to:
Workarounds
- Implement prepared statements or parameterized queries in the application code to prevent SQL injection
- Deploy a Web Application Firewall (WAF) with SQL injection detection rules in front of the application
- Apply strict input validation to the ID parameter, allowing only numeric values
- Restrict database user privileges to minimum required permissions following the principle of least privilege
- Consider replacing the vulnerable application with a more secure alternative if patches are not forthcoming
