## Description

Weak password recovery mechanisms can be exploited to take over user accounts. Common issues include predictable reset tokens, security questions with easily guessable answers, or lack of verification.

## Prevention

Strategie zapobiegania dla Weak Password Recovery oparte na 1 regułach detekcji Shoulder.

### Python

Use the secrets module for cryptographically secure token generation

## Warning Signs

- [HIGH] password reset tokens generated using weak or predictable methods like timestamps or non-cryptograph

## Consequences

- Uzyskanie uprawnień
- Obejście mechanizmu ochrony

## Mitigations

- Do linków resetowania hasła używaj mocnych, losowych tokenów
- Wdroż wygasanie tokenów (np. po 1 godzinie)
- Wymagaj dodatkowej weryfikacji, np. e-mailem lub SMS-em
- Nigdy nie umieszczaj tokenu resetowania w URL-ach, które mogą być logowane

## Detection

- Total rules: 3
- Languages: go, javascript, typescript, python

## Rules by Language

### Python (1 rules)

- **Weak Password Reset Token** [HIGH]: Detects password reset tokens generated using weak or predictable methods like timestamps or non-cryptographic random.
  - Remediation: Use the secrets module for cryptographically secure token generation.

```python
import secrets
token = secrets.token_urlsafe(32)
```
