🔧 Temporary Workarounds

Implement Input Validation in login.php

all

Add proper input validation and parameterized queries to the login.php file to prevent SQL injection

# Edit login.php to replace vulnerable code with prepared statements
# Example PHP fix:
# $stmt = $conn->prepare('SELECT * FROM users WHERE username = ? AND password = ?');
# $stmt->bind_param('ss', $username, $password);
# $stmt->execute();

Web Application Firewall (WAF) Rules

all

Deploy WAF rules to block SQL injection attempts on login endpoints

# Example ModSecurity rule:
# SecRule ARGS "['"]\s*or\s*['"]" "phase:2,deny,id:1001,msg:'SQL Injection attempt'"
# SecRule ARGS "=\s*['"]" "phase:2,deny,id:1002,msg:'SQL Injection attempt'"
# Cloudflare WAF: Enable SQL Injection protection rules

🧯 If You Can't Patch

  • Immediately disable or remove the administration panel from public access
  • Implement network-level restrictions to only allow administrative access from trusted IP addresses

🔍 How to Verify

Check if Vulnerable:

Check if your website uses Jettweb PHP Hazir Haber Sitesi Scripti V3 by examining source code for vendor references, or attempt exploitation with: curl -X POST 'http://target/login.php' --data 'username=''or''1''=''1&password=''or''1''=''1'

Check Version:

# Check PHP files for version references: grep -r 'jettweb\|hazir\|haber' /var/www/ || grep -r 'V3' /var/www/

Verify Fix Applied:

Test the login functionality with SQL injection payloads to ensure they're rejected, and verify proper authentication is required

📡 Detection & Monitoring

Log Indicators:

  • Multiple failed login attempts with SQL syntax in parameters
  • Successful logins from unusual IP addresses
  • POST requests to login.php containing 'or', '=', or SQL operators in parameters

Network Indicators:

  • Unusual traffic patterns to administration panel
  • Requests containing SQL injection patterns in login parameters

SIEM Query:

source="web_logs" AND (uri_path="/login.php" OR uri_path="/admin/login.php") AND (http_method="POST") AND (param_value="*or*" OR param_value="*=*" OR param_value="*'*'*" OR param_value="*1=1*")
