Falhas do tipo CWE-749

190 resultados

Exposição de método ou função perigosa

Quando uma aplicação disponibiliza publicamente um método ou função que não deveria ser acessível, permitindo que atacantes a executem com consequências graves. O problema é expor funcionalidades sensíveis (como deleção de dados, mudança de permissões ou acesso a recursos críticos) sem validação adequada de quem está chamando.

Exemplo

Uma API REST expõe um endpoint `/admin/deleteUser` sem autenticação ou apenas com verificação de token fraco, permitindo qualquer pessoa deletar usuários da plataforma. Ou uma biblioteca carrega um método de configuração interna que permite alterar parâmetros de segurança diretamente via reflexão.

Como mitigar

Aplique princípio do menor privilégio: mantenha métodos sensíveis privados ou protegidos, exporte apenas o necessário e força autenticação + autorização rigorosa em tudo que fica acessível. Implemente validação de entrada e auditoria de quem acessa recursos críticos.
