Allocation of Resources Without Limits or Throttling
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.
Without limits on resource allocation, an attacker can consume all available resources, causing denial of service for legitimate users.
이 취약점을 수정하는 방법
3개의 Shoulder 탐지 규칙을 기반으로 한 Allocation Without Limits 예방 전략.
Set size limits on body parser middleware to prevent memory exhaustion
- app.use(express.json()); - app.use(express.urlencoded({ extended: true })); + app.use(express.json({ limit: '100kb' })); + app.use(express.urlencoded({ extended: true, limit: '100kb' }));
Add 'take' limits to all relation includes to prevent unbounded data loading and resource exhaustion
import { PrismaClient } from '@prisma/client'; const prisma = new PrismaClient(); app.get('/api/users/:id', async (req, res) => { const user = await prisma.user.findUnique({ where: { id: req.params.id }, include: { - posts: true, // Could be thousands of posts - comments: true, // Could be tens of thousands + posts: { + take: 20, + orderBy: { createdAt: 'desc' }, + select: { id: true, title: true, createdAt: true }, + }, + comments: { + take: 50, + orderBy: { createdAt: 'desc' }, + }, } }); res.json(user); });
Add rate limiting to authentication and expensive API endpoints
from flask import Flask, request, jsonify - - @app.route('/api/login', methods=['POST']) + 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)})
