🔧 Temporary Workarounds

Input Validation and Sanitization

all

Implement strict input validation for email parameter in login.php

Add input validation: filter_var($email, FILTER_VALIDATE_EMAIL)
Use prepared statements: $stmt = $conn->prepare('SELECT * FROM users WHERE email = ?'); $stmt->bind_param('s', $email);

Web Application Firewall Rules

all

Deploy WAF rules to block SQL injection patterns in login requests

ModSecurity rule: SecRule ARGS:email "@detectSQLi" "id:1001,phase:2,deny,status:403"

🧯 If You Can't Patch

  • Implement network segmentation to isolate vulnerable system
  • Deploy intrusion detection system monitoring for SQL injection patterns

🔍 How to Verify

Check if Vulnerable:

Test login.php with SQL injection payloads in email parameter: ' OR '1'='1

Check Version:

Check system documentation or admin panel for version information

Verify Fix Applied:

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

📡 Detection & Monitoring

Log Indicators:

  • Unusual SQL errors in application logs
  • Multiple failed login attempts with SQL patterns
  • Database query errors containing SQL injection payloads

Network Indicators:

  • HTTP POST requests to /login.php with SQL keywords in parameters
  • Unusual database connection patterns from web server

SIEM Query:

source="web_logs" AND uri="/login.php" AND (email="*OR*" OR email="*UNION*" OR email="*SELECT*" OR email="*--*")
