Descriptions

In the Zoom Client through 4.4.4 and RingCentral 7.0.136380.0312 on macOS, remote attackers can force a user to join a video call with the video camera active. This occurs because any web site can interact with the Zoom web server on localhost port 19421 or 19424. NOTE: a machine remains vulnerable if the Zoom Client was installed in the past and then uninstalled. Blocking exploitation requires additional steps, such as the ZDisableVideo preference and/or killing the web server, deleting the ~/.zoomus directory, and creating a ~/.zoomus plain file.

En el Cliente Zoom hasta versión 4.4.4 y RingCentral versión 7.0.136380.0312 en macOS, los atacantes remotos pueden forzar a un usuario a unirse a una llamada de video con la cámara de video activa. Esto ocurre porque cualquier sitio web puede interactuar con el servidor web de Zoom en el puerto host local 19421 o 19424. NOTA: una máquina permanece vulnerable si el cliente Zoom fue instalado en el pasado y luego se desinstaló. El bloqueo de la operación requiere pasos adicionales, tales como la preferencia ZDisableVideo y/o la eliminación del servidor web, suprimiendo el directorio ~/.zoomus y creando un archivo plano ~/.zoomus.
