Injeção de comandos do sistema operacional

A aplicação constrói comandos do SO usando entrada do usuário sem sanitizar adequadamente, permitindo que um atacante injete comandos arbitrários. Quando a entrada contém metacaracteres (como `|`, `;`, `&&`, backticks), o shell interpreta-os como operadores, executando código não intencional com os privilégios da aplicação.

Example

Um script PHP que executa `system('ping ' . $_GET['host'])` permite um atacante passar `127.0.0.1; rm -rf /` como parâmetro, executando deleção de arquivos. Ou em Java, `Runtime.exec()` com strings concatenadas do usuário sem validação.

How to mitigate

Use APIs que não invocam shell (ex: `execvp()` em C, arrays de parâmetros em Java/Python, ou prepared commands). Se inevitável usar shell, escape rigorosamente com funções específicas (`escapeshellarg()` em PHP) ou valide contra whitelist de caracteres permitidos. Nunca confie em blacklist de caracteres perigosos.
