Falha no Mecanismo de Proteção

É uma fraqueza genérica que abrange falhas em controles de segurança implementados para proteger o software—como validação, autenticação, criptografia ou controle de acesso—que não funcionam corretamente ou podem ser contornados. Quando esses mecanismos falham, o software fica exposto a ataques que deveriam ser prevenidos.

Example

Um sistema implementa CORS para restringir requisições cross-origin, mas a configuração está errada (aceita qualquer origem), permitindo que um atacante roube dados sensíveis via JavaScript malicioso executado em outro site. Ou um login exige senha forte, mas o algoritmo de hashing usado é fraco (MD5), permitindo força bruta rápida.

How to mitigate

Valide e teste rigorosamente cada mecanismo de proteção (autenticação, autorização, validação de entrada, criptografia) em cenários de ataque reais. Não confie em defaults de bibliotecas—revise configurações de segurança, use bibliotecas criptográficas consolidadas, implemente rate limiting, e mantenha logs e alertas para detectar tentativas de contorno.
