Falhas do tipo CWE-327

401 resultados

Uso de algoritmo criptográfico quebrado ou inseguro

A aplicação usa um algoritmo de criptografia que já foi criptanaliticamente quebrado ou é considerado inseguro para o caso de uso. Isso expõe dados sensíveis a decriptação não autorizada, mesmo que o código implemente corretamente a biblioteca criptográfica escolhida.

Exemplo

Um sistema de autenticação usa MD5 ou SHA1 para hash de senhas, ou uma API de pagamento trafega dados com DES ou RC4 em vez de AES. Um atacante consegue recuperar a senha original via força bruta ou quebra criptanalítica em tempo viável.

Como mitigar

Use apenas algoritmos criptográficos modernos e bem mantidos: SHA-256+ para hash, AES-256 para cifra simétrica, RSA-2048+ ou ECDP-256+ para assimétrica. Audite regularmente o stack criptográfico e mantenha dependências atualizadas; remova suporte a algoritmos legados em produção.
