ID de CVE: CVE-2022-31231
Gravidade: Média
Quem deve executar este procedimento?
A Dell solicita que este procedimento de upgrade do xDoctor e a instalação do patch sejam feitos pelos Clientes. Esse é o método mais rápido e seguro, pois evita a exposição prolongada a essa vulnerabilidade. Todas as etapas estão detalhadas neste artigo da KB. Há também um guia de vídeo que pode ser seguido para acompanhar este artigo da KB que está localizado no link abaixo.
Impacto do procedimento:
tempos de espera excedidos de E/S podem ocorrer enquanto os serviços dataheadsvc são reiniciados nó por nó. Os aplicativos devem acessar o cluster por meio de um balanceador de carga e devem ser capazes de lidar com o tempo de espera excedido de E/S. Aconselhamos deixar uma janela de manutenção ao executar este procedimento.
Buckets somente de CAS. Exceção:
se todos os buckets de um sistema forem exclusivamente CAS destacados abaixo, ele não será afetado por essa vulnerabilidade de segurança. Portanto, não é necessário aplicar o patch e esse KB não precisa ser seguido.
Comando: svc_bucket list
Exemplo:
admin@ecs-n1:~> svc_bucket list

Tempo necessário para a atividade (aproximadamente):
um atraso de 60 segundos é definido por padrão por nó entre as reinicializações do serviço. O número de nós em um VDC (Virtual Data Center, data center virtual) multiplicado por 60 segundos + 30 minutos para preparação, estabilização do serviço e verificações posteriores necessárias.
Exemplos:
um sistema VDC de 48 nós pode levar aproximadamente 80 minutos:
60 segundos X 48 (número de nós do VDC) + 30 minutos (preparação) = 80 minutos aprox.
Um sistema VDC de 8 nós pode levar aproximadamente 40 minutos:
60 segundos X 8 (número de nós do VDC) + 30 minutos (preparação) = 40 minutos aprox.
Perguntas frequentes (FAQ):
P: O patch faz parte da versão do xDoctor?
R: O script de instalação de patch faz parte da versão 4.8-84 e posterior do xDoctor. As instruções para o download do xDoctor e a execução da instalação do patch estão nas etapas de resolução.
P: Posso atualizar vários VDCs em paralelo?
R: Não, aplique o patch em um VDC de cada vez.
P: Se eu fizer upgrade do ECS depois de executar este procedimento, posso executar novamente o procedimento após o upgrade?
R: Não, se estiver fazendo upgrade para uma versão de código especificada no DSA-2022-153 que tenha a correção permanente. Sim, se estiver fazendo upgrade para uma versão de código não especificada neste mesmo DSA.
P: O patch precisa ser reaplicado em um sistema em que foi instalado anteriormente após uma substituição de nó, recriação de imagem ou expansão?
R: Não, se o VDC estiver na versão de código especificada no DSA-2022-153 que tem a correção permanente. Sim, se estiver realizando qualquer uma dessas ações em relação a um VDC executando uma versão de código não especificada neste mesmo DSA. Quando o patch for necessário para esses cenários, o engenheiro da Dell em questão entrará em contato para informar que a atualização é necessária
P: E se eu estiver usando apenas usuários preexistentes e não estiver usando o IAM?
R: Os clientes precisam aplicar o patch, independentemente de usar apenas usuários preexistentes e não do IAM.
P: Com qual usuário você deve fazer login para executar todos os comandos deste artigo da KB?
R: admin
P: O svc_patch precisa ser executado em todos os racks ou com um arquivo MACHINES especializado em que vários racks estão em um VDC?
R: Não, ele detecta automaticamente se existirem vários racks e aplica patches em todos os nós em todos os racks nesse VDC.
P: Percebi que a versão de destino do xDoctor não é mais 4.8-84.0. Por quê?
R: As versões do xDoctor ocorrem com frequência, portanto, é sempre recomendável fazer upgrade para a versão mais recente lançada. No entanto, se você executou anteriormente a correção usando a versão 4.8-84.0, o sistema estará totalmente protegido contra a vulnerabilidade e não precisará ser executado novamente.
Resumo da resolução:
Faça upgrade do software ECS xDoctor para a versão mais recente disponível.
