Weaknesses of type CWE-327

Uso de algoritmo criptográfico fraco ou quebrado

A aplicação usa algoritmos de criptografia que já foram quebrados ou são reconhecidamente fracos (como MD5, SHA-1, DES, RC4), deixando dados sensíveis vulneráveis a ataques práticos. Mesmo que o algoritmo ainda funcione tecnicamente, um adversário pode recuperar a mensagem ou falsificar assinaturas com esforço computacional viável.

Example

Um sistema armazena senhas de usuários com hash MD5, ou usa SHA-1 para assinar tokens JWT, ou criptografa dados financeiros com DES. Em todos esses casos, há ferramentas públicas que conseguem quebrar a proteção em horas ou dias.

How to mitigate

Substitua por algoritmos modernos: SHA-256 ou melhor para hash (ou Argon2/bcrypt para senhas), AES-256 para criptografia simétrica, ECDSA ou RSA-2048+ para assinaturas. Revise periodicamente o acervo de dependências e remova bibliotecas que só ofereçam primitivas fracas.
