A HP é uma das maiores fabricantes de impressoras no mercado, e como tal, qualquer falha que afete as mesmas possui um forte impacto sobre os consumidores. E recentemente a empresa revelou que pelo menos 150 modelos das suas impressoras podem conter uma falha grave.
Segundo a empresa, as vulnerabilidades podem permitir que utilizadores maliciosos executem código na rede local da impressora, ou obtenham informações sensíveis dos utilizadores. A falha verifica-se sobre mais de 150 modelos de impressoras, algumas das quais lançadas ainda em 2013.
Sobre os códigos CVE-2021-39237 e CVE-2021-39238, as duas falhas descobertas foram corrigidas pela HP através de atualização do firmware, mas em muitos casos ainda cabe aos utilizadores descarregarem a versão mais recente do mesmo para garantirem que estão seguros.
A HP recomenda que os utilizadores desliguem o sistema de impressão via USB até que o patch tenha sido aplicado nas impressoras, além de colocarem as impressoras em redes separadas para evitar a exploração. As drivers e firmware mais recente para cada modelo pode ser descarregado a partir do site da HP.
