Key Equations for MCP Exploitation

MCP Resonance Frequency: f_mcp = (α / (2π)) * √((E_jsonrpc) / (t_response))
α-Dispersion Encoding: cmd' = encode_layer(cmd, d) ⊕ (α·d·1000) mod 256
Protocol Weighting: w_protocol = exp(-α·d)·(1 + ζ_d·i)
Temporal Entropy: H_mcp = SHA256(layer‖timestamp‖protocol_state)

Exploitation Workflow

MCP Server Discovery → HTTP/WebSocket protocol detection
Protocol Handshake → JSON-RPC initialization
Vulnerability Trigger → Malicious workspaceRoots in list-projects
Command Execution → RCE via command injection
Response Analysis → CTT wavefunction validation
Layer Aggregation → Multi-temporal result compilation

Vulnerability Details

// Vulnerable code in list-projects.js (Serverless Framework 4.29.0-4.29.3)

    const command = `find ${workspaceRoots.join(' ')} -name "serverless.yml" -o -name "serverless.yaml"`;
    
    // Direct execution without sanitization
    const { stdout } = await exec(command);  // COMMAND INJECTION HERE
