Javascript Insecure Ec Curve Secp192k1

Description

Detects usage of insecure elliptic curve SECP192K1 in cryptographic operations. This curve is considered cryptographically weak and provides insufficient security strength for modern applications. Using this curve could make the cryptographic system vulnerable to attacks.

Weakness:

052 - Insecure encryption algorithm

Category: Information Collection

Detection Strategy

    • Identifies declarations or uses of EC keypairs with the SECP192K1 curve in JavaScript code

    • Detects when crypto.createECDH() or similar EC functions are called with 'secp192k1' as parameter

    • Flags cryptographic operations that explicitly specify or use the SECP192K1 curve

Vulnerable code example

const crypto = require('crypto');

// Vulnerable: Using weak elliptic curve secp192k1 (< 224 bits)
crypto.generateKeyPair('ec', {
  namedCurve: 'secp192k1',  
  publicKeyEncoding: { type: 'spki', format: 'pem' },
  privateKeyEncoding: { type: 'pkcs8', format: 'pem' }
}, (err, publicKey, privateKey) => {...

✅ Secure code example

const crypto = require('crypto');

// Secure: Using strong elliptic curve secp256r1 (256 bits)
crypto.generateKeyPair('ec', {
  namedCurve: 'prime256v1',  // Using NIST P-256 curve (secp256r1) which meets security standards
  publicKeyEncoding: { type: 'spki', format: 'pem' },
  privateKeyEncoding: { type: 'pkcs8', format: 'pem' }
}, (err, publicKey, privateKey) => {...
