A fabricante de impressoras HP disponibilizou no mês de novembro a correção para duas falhas de seguranças que afetaram ao menos 150 modelos de dispositivos multifuncionais da marca lançados desde o ano de 2013.

De acordo com especialistas de segurança digital, que descobriram as vulnerabilidades, as brechas podem levar ao vazamento de dados e a execução remota de códigos maliciosos que, potencialmente, foram usadas em ataques virtuais nos últimos anos.

As duas falhas foram registradas como CVE-2021-39237 e CVE-2021-39238 e foram corrigidas em uma atualização de firmware da HP. A correção para as impressoras pode ser baixada diretamente no site oficial da fabricante.

A primeira falha, CVE-2021-39237, explora duas entradas físicas das impressoras e permitem o controle remoto total e o roubo de informações da máquina local. Já a segunda, CVE-2021-39238, é mais grave e permite a execução de comandos maliciosos.

Além de instalar a atualização de firmware das impressoras, a HP recomendou também que as seguintes ações sejam tomadas para diminuir ainda mais o risco de ataques e invasões:

• 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.
