The version of Zoom Client for Meetings installed on the remote host is prior to 5.9.7. It is, therefore, affected by a vulnerability as referenced in the ZSB-22004 advisory.

  • The Zoom Client for Meetings for Windows prior to version 5.9.7, Zoom Rooms for Conference Room for Windows prior to version 5.10.0, Zoom Plugins for Microsoft Outlook for Windows prior to version 5.10.3, and Zoom VDI Windows Meeting Clients prior to version 5.9.6; was susceptible to a local privilege escalation issue during the installer repair operation. A malicious actor could utilize this to potentially delete system level files or folders, causing integrity or availability issues on the user’s host machine. Users can help keep themselves secure by applying current updates or downloading the latest Zoom software with all current security updates from https://zoom.us/download. (CVE-2022-22782)

Note that Nessus has not tested for this issue but has instead relied only on the application’s self-reported version number.
