Insecure service configuration - OTP

Description​

The OTP mock is still enabled in the application.

Impact​

  • Attacker with information from a user of the application gets to the point where the OTP is requested.
  • Enters default OTP and successfully logs in to the application.

Recommendation​

Remove the OTP mock so that you can only login to the application with the OTP sent to the email.

Threat​

Unauthorized user with access to the application.

Expected Remediation Time​

⌚ 60 minutes.

Code Examples​

Compliant code​

The OTP service is securely configured, verifying the uniqueness of the code generated

const otpGenerator = require('otp-generator');
const { OTP_LENGTH, OTP_CONFIG } = require('../constants/constants');
//Implement a secure version of the OTP generator
module.exports.generateOTP = () => {
  const OTP = otpGenerator.generate(OTP_LENGTH, OTP_CONFIG);
  return OTP;
};

OTP_CONFIG: {
  upperCaseAlphabets: true,
  specialChars: false,
},

Non compliant code​

The OTP service is insecurely configured to allow default access

const otpGenerator = require('otp-generator');
const { OTP_LENGTH, OTP_CONFIG } = require('../constants/constants');
//The code still contains the default OTP used during development
module.exports.generateOTP = () => {
  const OTP = "OneTimeValue";
  return OTP;
};

OTP_CONFIG: {
  upperCaseAlphabets: true,
  specialChars: false,
},
