Injeção de comando via entrada não sanitizada

O software constrói comandos (shell, SQL, LDAP, etc.) usando dados de entrada do usuário sem neutralizar caracteres especiais que alteram a semântica do comando. Um atacante injeta metacaracteres (como `;`, `|`, `$()`) para executar instruções não previstas.

Ejemplo

Um script PHP que executa `system('ping ' . $_GET['host'])` sem validação. Um atacante passa `8.8.8.8; rm -rf /` e consegue deletar arquivos, porque o ponto-e-vírgula encadeia comandos no shell.

Cómo mitigar

Use APIs de execução que separam dados de comando (ex: `execvp()` com array de argumentos em vez de shell, prepared statements para SQL). Se shell for inevitável, whitelist rigoroso de entrada e escape apropriado com `escapeshellarg()` ou equivalente na linguagem.
