🛠️ 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 implementing workarounds.

🔧 Temporary Workarounds

Input Validation Filter

all

Add input validation to sanitize the ID parameter in /edit.php

Modify /edit.php to validate ID parameter: if(!is_numeric($_GET['ID'])) { die('Invalid input'); }

WAF Rule Implementation

all

Deploy web application firewall rules to block SQL injection patterns

Add WAF rule: SecRule ARGS:ID "@rx (?i)(union|select|insert|update|delete|drop|create|alter)" "id:1001,phase:2,deny,status:403,msg:'SQLi attempt detected'"

🧯 If You Can't Patch

  • Isolate the system behind a firewall with strict access controls
  • Implement network segmentation to limit database access from the web server

🔍 How to Verify

Check if Vulnerable:

Test /edit.php with SQL injection payloads like: /edit.php?ID=1' OR '1'='1

Check Version:

Check system version in admin panel or readme files

Verify Fix Applied:

Test with same payloads after implementing fixes - should return error or no database interaction

📡 Detection & Monitoring

Log Indicators:

  • Unusual SQL queries in database logs
  • Multiple failed login attempts from single IP
  • Requests to /edit.php with SQL keywords in parameters

Network Indicators:

  • HTTP requests containing SQL keywords (UNION, SELECT, etc.) in URL parameters
  • Unusual database connection patterns from web server

SIEM Query:

source="web_logs" AND url="/edit.php" AND (query="*UNION*" OR query="*SELECT*" OR query="*OR '1'='1*")
