🛠️ Fix & Mitigation
✅ Official Fix
Patch Version: Unknown
Vendor Advisory: None available
Restart Required: No
Instructions:
1. Check for updated version from vendor
2. If no patch available, implement workarounds
3. Consider replacing with alternative software
🔧 Temporary Workarounds
Input Validation Filter
allAdd server-side validation to ensure id parameter contains only numeric values
In delete.php, add: if(!is_numeric($_GET['id'])) { die('Invalid input'); }
Parameterized Query Implementation
allReplace raw SQL queries with prepared statements using PDO or mysqli
Replace: $sql = "DELETE FROM complaints WHERE id='" . $_GET['id'] . "'";
With: $stmt = $pdo->prepare("DELETE FROM complaints WHERE id=?"); $stmt->execute([$_GET['id']]);
🧯 If You Can't Patch
- Implement web application firewall (WAF) with SQL injection rules
- Restrict network access to only trusted IP addresses
- Monitor and log all delete.php requests for suspicious patterns
🔍 How to Verify
Check if Vulnerable:
Test delete.php with SQL injection payloads like: delete.php?id=1' OR '1'='1Check Version:
Check software version in admin panel or configuration filesVerify Fix Applied:
Test with same payloads and verify they are rejected or properly handled📡 Detection & Monitoring
Log Indicators:
- Unusual SQL errors in application logs
- Multiple delete requests with non-numeric id parameters
- Requests containing SQL keywords like UNION, SELECT, OR
Network Indicators:
- HTTP requests to delete.php with suspicious parameters
- Unusual database query patterns from web server
SIEM Query:
source="web_logs" AND uri="*delete.php*" AND (param="*id=*'*" OR param="*id=*%27*")
