Falhas do tipo CWE-427

922 resultados

Caminho de busca ou elemento não controlado

A aplicação procura por um recurso (arquivo, biblioteca, módulo) em múltiplos diretórios sem validar ou controlar a ordem de busca, permitindo que um atacante injete um arquivo malicioso em um caminho que será verificado primeiro. Isso leva a execução de código não autorizado ou bypass de controles de segurança.

Exemplo

Um programa em C carrega uma biblioteca dinâmica (DLL no Windows ou SO no Linux) procurando em diretórios listados em uma variável de ambiente. Se o atacante conseguir escrever um arquivo malicioso com o mesmo nome em um diretório anterior da busca (como o diretório atual), a aplicação carrega a versão maliciosa sem questionar.

Como mitigar

Use caminhos absolutos e hardcoded para recursos críticos; nunca confie em variáveis de ambiente para localizá-los. Valide hash ou assinatura digital de bibliotecas carregadas e restrinja permissões de escrita nos diretórios de busca apenas ao administrador.
