HP corrige falha de segurança que atinge 150 modelos de impressoras

·6 min de leitura

Pesquisadores descobriram que pelo menos 150 modelos de impressoras multifuncionais da HP sofrem com várias brechas que podem levar ao vazamento de dados e execução remota de códigos maliciosos. As vulnerabilidades estão presentes em dispositivos lançados desde 2013, o que significa que, potencialmente, foram usadas para ataques virtuais durante os últimos oito anos.

As falhas foram documentadas como CVE-2021-39237 e CVE-2021-39238. As vulnerabilidades mais críticas delas foram corrigidas na atualização de firmware para as impressoras afetadas lançadas pela HP no começo de novembro.

São duas falhas. A primeira, CVE-2021-39237, explora duas entradas físicas das impressoras e permitem o controle remoto total, inclusive com roubo de informações da máquina local. A segunda, CVE-2021-39238, é ainda mais grave, pois permite a execução de comandos maliciosos que podem se espalhar pela rede.

Além da atualização de firmware das impressoras, a HP recomenda que as seguintes ações sejam tomadas para diminuir ainda mais o risco:

  • Desabilitar impressão via USB;

  • Deixar a impressora conectada em uma rede separada para evitar propagação de ameaças, e limitar quem pode acessá-la;

  • Configurar um servidor exclusivo para comunicação entre computadores e as impressoras.

As atualizações de firmware para as impressoras podem ser baixadas no site oficial da HP.
