Arquivos ou diretórios acessíveis a terceiros

A aplicação ou servidor expõe arquivos ou diretórios com permissões insuficientes, permitindo que usuários não autorizados (locais ou remotos) leiam, modifiquem ou executem conteúdo sensível. O risco varia desde exposição de dados confidenciais até execução de código malicioso, dependendo do que está exposto e das permissões concedidas.

Exemplo

Um servidor web servindo a pasta /uploads com permissões 777, onde backup de banco de dados ou chaves privadas ficam armazenadas. Qualquer pessoa com acesso à rede (ou internet, se o servidor estiver exposto) consegue baixar esses arquivos. Outro cenário: arquivo de configuração com credenciais legível por todos em /etc/app/config.txt.

Como mitigar

Implemente o princípio do menor privilégio: defina permissões de arquivo e diretório restritivas (ex: 640, 750), revise listas de controle de acesso (ACLs), separe dados sensíveis de diretórios servidos publicamente, e audite regularmente permissões em produção usando ferramentas de varredura (find, stat, ou análise de ACLs).
