Injeção em logs (Log Injection)

O software escreve dados não sanitizados nos logs, permitindo que um atacante injete conteúdo malicioso (quebras de linha, caracteres de controle, formatação falsa) que pode ser interpretado como eventos legítimos, mascarar atividades suspeitas ou enganar ferramentas de monitoramento.

Exemplo

Um servidor web registra a URL solicitada diretamente no log sem filtrar quebras de linha. Um atacante envia requisição com payload como `/page?id=123%0aAdmin login failed`, que escreve nos logs como se fosse dois eventos separados, ocultando a atividade real ou imitando um acesso autorizado.

Como mitigar

Sanitize todos os dados antes de escrever em logs: remova ou escape caracteres de controle (\n, \r, \0), use formatação estruturada (JSON, syslog) em vez de concatenação de strings, e implemente validação rigorosa de entrada. Ferramentas de SIEM devem também rejeitar logs com estrutura inesperada.
