The version of Zoom Client for Meetings installed on the remote host is prior to 5.14.0. It is, therefore, affected by a vulnerability as referenced in the ZSB-23014 advisory.

  • Improper input validation in the installer for Zoom for Windows clients before 5.14.0 may allow an authenticated user to potentially enable an escalation of privilege via local access. 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-2023-34122)

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