Falta de sanitização em logs

O software escreve dados não validados diretamente nos logs sem neutralizar caracteres especiais ou sequências perigosas. Isso permite que um atacante injete conteúdo malicioso (como quebras de linha, comandos ou payloads) que será processado ou interpretado por ferramentas de análise de logs, levando a falsificação de registros, execução de código ou bypass de detecção.

Example

Um usuário envia um campo de nome contendo quebras de linha e texto malicioso. O aplicativo escreve diretamente no log: 'Usuário: Alice\nADMIN: Acesso negado revogado'. Ferramentas ou analistas lendo o log são enganadas, acreditando que o acesso foi realmente revogado.

How to mitigate

Sempre sanitize dados antes de escrever em logs: remova ou escape caracteres de controle (\n, \r, \t), use codificação apropriada (URL encoding, JSON escaping) ou substitua por espaços/asteriscos. Considere estruturado formato de logs (JSON, CEF) que lida melhor com caracteres especiais.
