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.
