Weaknesses of type CWE-326

208 results

Força criptográfica inadequada

A aplicação usa algoritmos ou tamanhos de chave criptográfica insuficientes para proteger dados sensíveis contra ataques conhecidos. Por exemplo, usar DES, MD5 ou chaves RSA de 512 bits fornece proteção que pode ser quebrada em tempo viável com poder computacional moderno, deixando dados expostos.

Example

Um sistema de autenticação que armazena senhas hasheadas com MD5, ou uma API que criptografa dados com DES em vez de AES-256. Um atacante com acesso aos hashes consegue recuperar as senhas por força bruta, ou quebra a criptografia DES em horas.

How to mitigate

Use algoritmos reconhecidos como seguro (AES-256 para cifra simétrica, RSA 2048+ ou ECDSA para assimétrica, bcrypt/scrypt/argon2 para senhas). Revise regularmente o padrão criptográfico da sua stack — o que era seguro em 2015 pode estar comprometido hoje.
