🛠️ Fix & Mitigation
✅ Official Fix
Patch Version: Unknown
Vendor Advisory: https://www.sourcecodester.com/
Restart Required: No
Instructions:
No official patch available. Consider upgrading to a newer version if available, or implement workarounds.
🔧 Temporary Workarounds
Input Validation and Sanitization
allImplement strict input validation and parameterized queries for the 'remark' parameter in test-details.php
Modify PHP code to use prepared statements: $stmt = $conn->prepare('SELECT * FROM table WHERE remark = ?'); $stmt->bind_param('s', $remark);
Web Application Firewall (WAF) Rules
allDeploy WAF rules to block SQL injection patterns targeting the /test-details.php endpoint
Add WAF rule: Block requests to /test-details.php with SQL injection patterns in parameters
🧯 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 endpoint
🔍 How to Verify
Check if Vulnerable:
Test the /test-details.php endpoint with SQL injection payloads in the 'remark' parameter and observe database errors or unexpected behavior.Check Version:
Check the software version in the admin panel or configuration files, typically in config.php or similar files.Verify Fix Applied:
After implementing parameterized queries, test with SQL injection payloads and verify no database errors or unauthorized access occurs.📡 Detection & Monitoring
Log Indicators:
- SQL syntax errors in web server logs
- Unusual database queries from web application
- Multiple failed login attempts or parameter manipulation
Network Indicators:
- HTTP requests to /test-details.php with SQL keywords in parameters
- Unusual database connection patterns from web server
SIEM Query:
source="web_server" AND uri="/test-details.php" AND (param="remark" AND value CONTAINS "UNION" OR value CONTAINS "SELECT" OR value CONTAINS "OR 1=1")
