Travessia de diretório (Path Traversal)

A aplicação constrói caminhos de arquivo usando entrada do usuário sem validar adequadamente, permitindo que caracteres especiais como '../' façam o caminho "sair" do diretório permitido e acessar arquivos fora da zona restrita. Isso expõe dados sensíveis ou permite manipulação de arquivos críticos do sistema.

Exemplo

Um site permite download de documentos via URL como /download?file=relatorio.pdf, mas não valida o parâmetro. Um atacante usa /download?file=../../etc/passwd para ler o arquivo de senhas do servidor, ou /download?file=../../configuracao.db para acessar a base de dados da aplicação.

Como mitigar

Valide e normalize todos os caminhos de entrada (use funções nativas como realpath ou canonicalize), implemente uma whitelist de arquivos permitidos em vez de bloquear padrões perigosos, e configure permissões de arquivo restritivas no SO. Melhor ainda: nunca construa caminhos a partir de entrada do usuário — use índices ou IDs mapeados internamente.
