Preservação inadequada de permissões

Quando um programa cria, copia ou modifica arquivos e recursos, mas não mantém ou herda as permissões originais corretamente, permitindo acesso indevido. Isso expõe dados sensíveis ou permite que usuários não autorizados executem operações críticas.

Exemplo

Um backup que copia arquivos de configuração com credenciais, mas muda as permissões para leitura por qualquer usuário do sistema. Ou um instalador que cria diretórios temporários com permissões padrão abertas, deixando senhas de sessão visíveis para outros usuários locais.

Como mitigar

Sempre defina explicitamente permissões restritivas (ex: 0600 para arquivos sensíveis) logo após criar ou copiar arquivos. Use funções seguras da plataforma (chmod, SetSecurityDescriptor) e valide que as permissões foram aplicadas corretamente antes de escrever dados sensíveis.
