Falha em Mecanismo de Proteção

CWE-693 descreve quando um mecanismo de segurança implementado no software não funciona como deveria, seja por design deficiente, implementação incorreta ou bypass não intencional. O resultado é que uma ou mais camadas de defesa falham, deixando o sistema exposto a ataques que deveriam ter sido bloqueados.

Exemplo

Um sistema implementa validação de entrada apenas no cliente (JavaScript), mas deixa a API backend sem validação equivalente. Um atacante contorna a proteção do cliente e envia dados maliciosos diretamente para o servidor, que as aceita sem filtro. O mecanismo de proteção falhou porque estava incompleto.

Como mitigar

Implementar controles de segurança em profundidade (nunca confiar apenas em uma camada), validar e sanitizar dados em todos os pontos de entrada, testar regularmente se as proteções estão funcionando conforme esperado, e documentar claramente qual é a intenção de cada controle de segurança.
