CVE-2025-63531
📋 TL;DR
This SQL injection vulnerability in Blood Bank Management System 1.0 allows attackers to bypass authentication by injecting malicious SQL code through login fields. Any organization using this specific blood bank management software is affected. Attackers can gain unauthorized access to sensitive medical data and system controls.
💻 Affected Systems
- Blood Bank Management System
📦 What is this software?
⚠️ Risk & Real-World Impact
Worst Case
Complete system compromise allowing data theft, manipulation of blood bank records, potential patient harm through incorrect blood matching, and lateral movement to connected systems.
Likely Case
Unauthorized access to sensitive patient data, manipulation of blood inventory records, and potential ransomware deployment.
If Mitigated
Limited impact with proper input validation and database permissions, potentially only allowing authentication bypass without further system access.
🎯 Exploit Status
Simple SQL injection requiring no authentication. Public proof-of-concept available in GitHub repositories.

Vendor Advisory: Not available
Restart Required: No
Instructions:
No official patch available. Implement workarounds or migrate to secure alternative software.
🔧 Temporary Workarounds
Input Validation and Parameterized Queries
allModify receiverLogin.php to use prepared statements with parameterized queries instead of concatenating user input.
Replace vulnerable SQL queries with: $stmt = $conn->prepare('SELECT * FROM receiver WHERE remail = ? AND rpassword = ?'); $stmt->bind_param('ss', $email, $password); $stmt->execute();
Web Application Firewall (WAF)
allDeploy WAF with SQL injection rules to block malicious payloads.
🧯 If You Can't Patch
- Isolate the system from internet access and restrict to internal network only
- Implement strict network segmentation and monitor all access to the vulnerable component
🔍 How to Verify
Check if Vulnerable:
Test login page with SQL injection payloads like: remail=admin' OR '1'='1&rpassword=anythingCheck Version:
Check PHP files for version comments or review installation documentationVerify Fix Applied:
Attempt SQL injection payloads after implementing parameterized queries; successful login should only occur with valid credentials.📡 Detection & Monitoring
Log Indicators:
- Multiple failed login attempts with SQL keywords
- Successful logins from unusual IP addresses
- Database error messages containing user input
Network Indicators:
- HTTP POST requests to receiverLogin.php containing SQL keywords
- Unusual database query patterns
SIEM Query:
source="web_logs" AND uri="/receiverLogin.php" AND (request_body CONTAINS "OR '1'='1" OR request_body CONTAINS "UNION SELECT" OR request_body CONTAINS "--")
