Injeção de comando por entrada não neutralizada

O software monta um comando (shell, sistema operacional ou aplicação) usando dados recebidos de fora (entrada do usuário, API, banco de dados) sem remover ou neutralizar caracteres especiais que alteram a semântica do comando. Isso permite que um atacante injete comandos arbitrários que serão executados com as permissões da aplicação.

Example

Um script PHP que executa ping com o IP fornecido pelo usuário: `system('ping ' . $_GET['ip'])`. Um atacante passa `8.8.8.8; rm -rf /` e consegue deletar arquivos do servidor, porque o ponto-e-vírgula não foi escapado e o shell interpreta dois comandos sequenciais.

How to mitigate

Use APIs seguras que não envolvem interpretação de shell (ex: ProcessBuilder em Java, subprocess.run com shell=False em Python). Se imperativo usar shell, valide com whitelist rigorosa (apenas caracteres alfanuméricos/IPs válidos) e escape com funções específicas da linguagem (escapeshellarg em PHP, shlex.quote em Python).
