Falhas do tipo CWE-78
5.061 resultadosInjeção de comando do sistema operacional
A aplicação constrói comandos do SO usando dados de entrada do usuário sem sanitização adequada, permitindo que um atacante injete comandos adicionais. Quando o comando é executado, instruções maliciosas do atacante rodam com os privilégios da aplicação, comprometendo o servidor.
Exemplo
Um script PHP que executa `system('ping ' . $_GET['host'])` sem validar o parâmetro. Um atacante passa `8.8.8.8; rm -rf /` e consegue deletar arquivos do servidor, não apenas fazer ping.
Como mitigar
Sempre valide e sanitize entrada de usuário; prefira APIs seguras (como funções que aceitam argumentos separados em vez de strings de comando); execute com menor privilégio necessário; use listas brancas de valores permitidos quando possível.
