Preservação inadequada de permissões

Ocorre quando uma aplicação cria, copia ou modifica arquivos, processos ou recursos sem manter ou validar as permissões de acesso originais. Isso permite que usuários não autorizados acessem dados sensíveis ou executem operações privilégiadas que deveriam estar restritas.

Example

Um backup de banco de dados é criado com permissões world-readable porque o código copia o arquivo sem preservar o mode 0600 do original, expondo credenciais de produção a qualquer usuário do servidor. Ou um processo filho herda mais privilégios que deveria porque o pai não descarta capabilities do Linux antes de exec().

How to mitigate

Sempre defina explicitamente permissões restritivas ao criar ou copiar recursos sensíveis (chmod 0600 para arquivos, setfacl para ACLs). Valide permissões antes de acessar e remova privilégios desnecessários antes de executar código não confiável (chown, chgrp, umask consciente).
