Falhas do tipo CWE-665

166 resultados

Inicialização inadequada de recursos

O software falha em inicializar corretamente um recurso (memória, arquivo, conexão, variável) ou não o inicializa antes de usá-lo, deixando-o em estado indefinido. Isso pode levar a comportamentos imprevisíveis, leitura de dados lixo, corrupção de estado ou exploração de segurança quando o recurso é acessado ou manipulado.

Exemplo

Um buffer alocado dinamicamente que nunca é zerado antes de usar em operações criptográficas, permitindo que dados sensíveis anteriormente armazenados naquele espaço de memória vaze. Ou uma estrutura de configuração que não inicializa seus campos, deixando ponteiros inválidos que podem ser dereferenciados.

Como mitigar

Sempre inicialize explicitamente todo recurso no momento da criação ou alocação (memset, construtores, atribuições de valor padrão). Use ferramentas estáticas (lint, compilador com warnings, SAST) para detectar variáveis não inicializadas e valide estados esperados antes de usar qualquer recurso.
