Essa semana ocorreu o “Microsoft’s February 2023 Patch Tuesday” e as atualizações de segurança liberadas corrigem três vulnerabilidades de zero-day exploradas ativamente e um total de 77 falhas.
Nove vulnerabilidades foram classificadas como ‘Críticas’, pois permitem a execução remota de código em dispositivos vulneráveis.
O número de bugs em cada categoria de vulnerabilidade está listado abaixo:
- 12 Elevation of Privilege
- 2 Security Feature Bypass
- 38 Remote Code Execution
- 8 Information Disclosure
- 10 Denial of Service
- 8 Spoofing
As três vulnerabilidades de zero-day exploradas ativamente corrigidas nas atualizações de hoje são:
CVE-2023-21823 – Vulnerabilidade de execução remota de código do componente gráfico do Windows descoberta por Dhanesh Kizhakkinan, Genwei Jiang e Dhanesh Kizhakkinan da Mandiant.
A Microsoft diz que essa vulnerabilidade de execução remota de código permite que invasores executem comandos com privilégios de SISTEMA.
Esta atualização de segurança será enviada aos usuários por meio da Microsoft Store, em vez do Windows Update. Portanto, para os clientes que desabilitam as atualizações automáticas na Microsoft Store, a Microsoft não enviará a atualização automaticamente.
CVE-2023-21715 – Vulnerabilidade de bypass dos recursos de segurança do Microsoft Publisher descoberta por Hidetake Jo da Microsoft.
A segunda vulnerabilidade de dia zero está no Microsoft Publisher e permite que um documento especialmente criado ignore as políticas de macro do Office que bloqueiam arquivos não confiáveis ou maliciosos.
A exploração dessa falha permitiria efetivamente que as macros em um documento malicioso do Publisher fossem executadas sem primeiro avisar o usuário.
“O ataque em si é realizado localmente por um usuário com autenticação no sistema visado”, explica a Microsoft.
“Um invasor autenticado pode explorar a vulnerabilidade convencendo a vítima, por meio de engenharia social, a baixar e abrir um arquivo especialmente criado de um site que pode levar a um ataque local no computador da vítima”.
CVE-2023-23376 – Vulnerabilidade de elevação de privilégio do driver do sistema de arquivos de log comum do Windows descoberta pelo Microsoft Threat Intelligence Center (MSTIC) e pelo Microsoft Security Response Center (MSRC).
A terceira vulnerabilidade explorada ativamente permite que um “invasor que explorou com sucesso esta vulnerabilidade possa obter privilégios de SISTEMA”.
