9VSA-00048-001 CSIRT comparte actualizaciones de Microsoft, parches críticos para RCE y para RDP cliente

Resumen

El Equipo de Respuesta ante Incidentes de Seguridad Informática, CSIRT, comparte la información entregada por Microsoft en su reporte mensual de actualizaciones correspondiente a septiembre del 2019, parchando un total de 79 vulnerabilidades en sus softwares. Del total anterior, 17 han sido clasificados como críticos, 61 como importantes y uno como moderado.

Además se recalca que 4 de los parches críticos hacen referencia a vulnerabilidades de ejecución remota arbitraria de código o RCE (por sus siglas en inglés) para la aplicación integrada de cliente de escritorio remoto de Windows, lo que podría permitir que un servidor RDP malicioso comprometa el equipo del cliente.

A diferencia del error de BlueKeep, las vulnerabilidades RDP recién parcheadas son todas del lado del cliente, lo que requiere que un atacante engañe a las víctimas para que se conecten a un servidor RDP malicioso a través de ingeniería social, envenenamiento de DNS o utilizando una técnica Man in the Middle (MITM).
