Injeção em logs (Log Injection)

O software escreve dados do usuário ou de fontes externas diretamente nos logs sem sanitização, permitindo que um atacante injete mensagens falsas, quebre a estrutura do log ou esconda evidências. Isso compromete a auditoria, facilita ataques de negação de serviço e pode levar a falsificação de registros de segurança.

Ejemplo

Um aplicativo web registra logins assim: `log.info("Usuário: " + username + " realizou login")`. Um atacante cria uma conta chamada `admin%0aUSUÁRIO AUTORIZADO: admin` e faz login, injetando uma linha fake no log que simula uma ação de administrador que nunca ocorreu.

Cómo mitigar

Sanitize sempre entradas de usuário antes de registrar (remova quebras de linha, caracteres de controle), use estrutura de logging estruturada (JSON, key-value) em vez de concatenação, e valide/filtre dados na origem. Implemente logs imutáveis ou com assinatura criptográfica para auditoria sensível.
