The version of Zoom VDI Meeting Client installed on the remote host is prior to 5.16.0. It is, therefore, affected by a vulnerability as referenced in the ZSB-23047 advisory.

  • Uncontrolled resource consumption in Zoom Team Chat for Zoom Desktop Client for Windows and Zoom VDI Client may allow an unauthenticated user to conduct a disclosure of information via network 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-2023-39203)

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