Descriptions

The Zoom Client for Meetings (for Android, iOS, Linux, macOS, and Windows) before version 5.10.0 fails to properly validate the hostname during a server switch request. This issue could be used in a more sophisticated attack to trick an unsuspecting users client to connect to a malicious server when attempting to use Zoom services.

Zoom Client for Meetings (para Android, iOS, Linux, macOS y Windows) anterior a la versión 5.10.0 no comprueba correctamente el nombre de host durante una petición de cambio de servidor. Este problema podría usarse en un ataque más sofisticado para engañar a un cliente de usuario desprevenido para que sea conectado a un servidor malicioso cuando intente usar los servicios de Zoom
