The version of Zoom Client for Meetings installed on the remote host is prior to 5.6.3. It is, therefore, affected by a vulnerability as referenced in the ZSB-22002 advisory.
Note that Nessus has not tested for this issue but has instead relied only on the application’s self-reported version number.

"The version of Zoom Client for Meetings installed on the remote host is prior to 5.6.3. It is, therefore, affected by a
vulnerability as referenced in the ZSB-22002 advisory.
- The Zoom Client for Meetings chat functionality was susceptible to Zip bombing attacks in the following
product versions: Android before version 5.8.6, iOS before version 5.9.0, Linux before version 5.8.6,
macOS before version 5.7.3, and Windows before version 5.6.3. This could lead to availability issues on
the client host by exhausting system resources. 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-2022-22780)
Note that Nessus has not tested for this issue but has instead relied only on the application's self-reported version
