# Weak Password Requirements (CWE-521)

The product does not require that users should have strong passwords, which makes it easier for attackers to compromise user accounts.

**Stack:** JavaScript

- Prevalence: उच्च बार-बार शोषित
- Impact: उच्च 1 उच्च गंभीरता वाले नियम
- Prevention: प्रलेखित 2 फिक्स उदाहरण

**OWASP:** Identification and Authentication Failures (A07:2021-Identification and Authentication Failures) - #7

## Description

Without strong password requirements, users often choose weak, easily guessable passwords. This makes brute-force and dictionary attacks more likely to succeed.

## Prevention

1 Shoulder डिटेक्शन नियमों पर आधारित Weak Password Requirements के लिए रोकथाम रणनीतियाँ।

### JavaScript

Require minimum 12 characters with complexity checks or use a password strength library

## Warning Signs

- [HIGH] Password validation at ... lacks proper complexity requirements
- [HIGH] password validation that lacks proper complexity requirements, making accounts vulnerable to brute f

## Consequences

- विशेषाधिकार प्राप्त करना
- सुरक्षा तंत्र को बायपास करना

## Mitigations

- न्यूनतम पासवर्ड लंबाई लागू करें (12 या अधिक वर्ण अनुशंसित)
- पासवर्डों की ज्ञात breach डेटाबेस से जाँच करें
- बहु-कारक प्रमाणीकरण लागू करें

- Languages: go, javascript, typescript

## Rules by Language

### Javascript (1 rules)

- **Weak Password Policy** [HIGH]: Detects password validation that lacks proper complexity requirements, making accounts vulnerable to brute force attacks.
  - Remediation: Implement strong password requirements:

```javascript
// ✅ SAFE - Strong password policy
function validatePassword(password) {
  if (password.length < 12) {
    throw new Error('Password must be at least 12 characters');
  }

  const hasUppercase = /[A-Z]/.test(password);
  const hasLowercase = /[a-z]/.test(password);
  const hasDigit = /\d/.test(password);
  const hasSpecial = /[!@#$%^&*(),.?":{}|<>]/.test(password);

  if (!hasUppercase || !hasLowercase || !hasDigit || !hasSpecial) {
    throw new Error(
      'Password must contain uppercase, lowercase, digit, and special character'
    );
  }

  return true;
}
```

### Typescript (1 rules)

- **Weak Password Policy** [HIGH]: Detects password validation that lacks proper complexity requirements, making accounts vulnerable to brute force attacks.
  - Remediation: Implement strong password requirements:

```javascript
// ✅ SAFE - Strong password policy
function validatePassword(password) {
  if (password.length < 12) {
    throw new Error('Password must be at least 12 characters');
  }

  const hasUppercase = /[A-Z]/.test(password);
  const hasLowercase = /[a-z]/.test(password);
  const hasDigit = /\d/.test(password);
  const hasSpecial = /[!@#$%^&*(),.?":{}|<>]/.test(password);

  if (!hasUppercase || !hasLowercase || !hasDigit || !hasSpecial) {
    throw new Error(
      'Password must contain uppercase, lowercase, digit, and special character'
    );
  }

  return true;
}
