🛠️ Fix & Mitigation
✅ Official Fix
Patch Version: Unknown
Vendor Advisory: https://www.sourcecodester.com/
Restart Required: No
Instructions:
No official patch available. Consider migrating to alternative banking management systems or implementing workarounds.
🔧 Temporary Workarounds
Input Validation and Sanitization
allImplement strict input validation and parameterized queries for the ID parameter in /bank/show.php
Modify PHP code to use prepared statements: $stmt = $conn->prepare('SELECT * FROM table WHERE id = ?'); $stmt->bind_param('i', $id);
Web Application Firewall Rules
allDeploy WAF rules to block SQL injection patterns targeting the /bank/show.php endpoint
Add WAF rule: Block requests to /bank/show.php containing SQL keywords like UNION, SELECT, INSERT, DELETE, DROP, OR 1=1
🧯 If You Can't Patch
- Isolate the system from internet access and restrict to internal network only
- Implement network segmentation and strict access controls to limit who can reach the vulnerable endpoint
🔍 How to Verify
Check if Vulnerable:
Test the /bank/show.php endpoint with SQL injection payloads like: /bank/show.php?id=1' OR '1'='1Check Version:
Check the software version in the application interface or configuration filesVerify Fix Applied:
Attempt SQL injection tests after implementing parameterized queries and verify they no longer succeed📡 Detection & Monitoring
Log Indicators:
- Unusual SQL errors in application logs
