🛠️ Fix & Mitigation
✅ Official Fix
Patch Version: Unknown
Vendor Advisory: https://code-projects.org/
Restart Required: No
Instructions:
1. Check vendor website for updates 2. Apply patch if available 3. Test functionality
🔧 Temporary Workarounds
Input Validation Filter
allAdd server-side validation to only accept numeric values for studentnum parameter
Add PHP validation: if(!is_numeric($_POST['studentnum'])) { die('Invalid input'); }
Parameterized Query Implementation
allReplace direct SQL concatenation with prepared statements
Replace: $sql = "INSERT INTO members (studentnum) VALUES ('" . $_POST['studentnum'] . "')";
With: $stmt = $conn->prepare("INSERT INTO members (studentnum) VALUES (?)"); $stmt->bind_param("s", $_POST['studentnum']);
🧯 If You Can't Patch
- Block external access to /addmem.php using web server configuration or firewall rules
- Implement Web Application Firewall (WAF) with SQL injection protection rules
🔍 How to Verify
Check if Vulnerable:
Test /addmem.php endpoint with SQL injection payloads like: studentnum=1' OR '1'='1Check Version:
Check application files or documentation for version informationVerify Fix Applied:
Test with same payloads and verify proper error handling or rejection📡 Detection & Monitoring
Log Indicators:
- Unusual SQL errors in application logs
- Multiple failed login attempts via /addmem.php
- Unexpected database queries containing SQL keywords
Network Indicators:
- HTTP POST requests to /addmem.php with SQL syntax in parameters
- Unusual database connection patterns from web server
SIEM Query:
source="web_logs" AND uri_path="/addmem.php" AND (request_body LIKE "%UNION%" OR request_body LIKE "%SELECT%" OR request_body LIKE "%OR%1%1%")
