🔧 Temporary Workarounds
Web Application Firewall (WAF) Rules
allDeploy WAF rules to block SQL injection patterns targeting /manager/card/card_detail.php
# Example ModSecurity rule: SecRule REQUEST_URI "@contains /manager/card/card_detail.php" "id:1001,phase:2,deny,msg:'SQLi attempt blocked'"
# Add SQL injection detection patterns specific to this endpoint
Network Access Control
linuxRestrict access to the vulnerable endpoint using firewall rules or network segmentation
# iptables example: iptables -A INPUT -p tcp --dport 80 -m string --string "/manager/card/card_detail.php" --algo bm -j DROP
# Alternative: Restrict to specific IP ranges only
🧯 If You Can't Patch
- Implement strict input validation and parameterized queries in the card_detail.php file
- Disable or remove the /manager/card/card_detail.php endpoint if not required for operations
🔍 How to Verify
Check if Vulnerable:
Test the /manager/card/card_detail.php endpoint with SQL injection payloads (e.g., ' OR '1'='1) and monitor for database errors or unexpected responses. Use tools like sqlmap with proper authorization.Check Version:
Check system documentation or web interface for version information. Typically found in admin panels or system info pages.Verify Fix Applied:
After applying fixes, retest with SQL injection payloads to ensure they are properly blocked or sanitized. Verify no database errors appear in responses.📡 Detection & Monitoring
