# Allocation of Resources Without Limits or Throttling (CWE-770)

The product allocates a reusable resource or group of resources on behalf of an actor without imposing any restrictions on the size or number of resources that can be allocated.

**Stack:** Python

- Prevalence: Élevée Fréquemment exploitée
- Impact: Moyen Revue recommandée
- Prevention: Documentée 3 exemples de correctifs

**OWASP:** Security Misconfiguration (A05:2021-Security Misconfiguration) - #5

## Description

Without limits on resource allocation, an attacker can consume all available resources, causing denial of service for legitimate users.

## Prevention

Stratégies de prévention pour Allocation Without Limits basées sur 1 règles de détection Shoulder.

### Python

Add rate limiting to authentication and expensive API endpoints

## Warning Signs

- [MEDIUM] API endpoint lacks rate limiting protection
- [MEDIUM] API endpoints without rate limiting

## Consequences

- DoS : consommation de ressources
- DoS : crash / sortie / redémarrage

## Mitigations

- Mettez en place un rate limiting pour toutes les allocations de ressources
- Définissez des limites maximales pour les pools de ressources
- Surveillez l'utilisation des ressources et mettez en place des alertes

## Detection

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

## Rules by Language

### Python (1 rules)

- **Missing API Rate Limiting** [MEDIUM]: Detects API endpoints without rate limiting. Unprotected endpoints are
vulnerable to brute force attacks, credential stuffing, and denial of service.
Always implement rate limiting on authentication, expensive operations, and
public APIs.
  - Remediation: Add rate limiting decorator to authentication and expensive endpoints.

```python
from flask_limiter import Limiter
from flask_limiter.util import get_remote_address

limiter = Limiter(app=app, key_func=get_remote_address)

@app.route('/api/login', methods=['POST'])
@limiter.limit("5 per minute")
def login():
    user = authenticate(request.json)
    return jsonify({'token': generate_token(user)})
```
