Descriptions

The Zoom Client for Meetings for Windows before version 5.10.0 and Zoom Rooms for Conference Room for Windows before version 5.10.0, fails to properly check the installation version during the update process. This issue could be used in a more sophisticated attack to trick a user into downgrading their Zoom client to a less secure version.

Zoom Client for Meetings para Windows versiones anteriores a 5.10.0 y Zoom Rooms for Conference Room para Windows versiones anteriores a 5.10.0, no comprueban apropiadamente la versión de instalación durante el proceso de actualización. Este problema podría ser usado en un ataque más sofisticado para engañar a un usuario para que actualice su cliente Zoom a una versión menos segura
