critical Nessus Plugin ID 168821

Synopsis

The remote host has an application installed that is affected by a vulnerability.

Description

The version of Zoom Client for Meetings installed on the remote host is prior to 5.3.0. It is, therefore, affected by a vulnerability as referenced in the ZSB-21003 advisory.

- The Zoom Client for Meetings for Windows in all versions before 5.3.0 fails to properly validate the certificate information used to sign .msi files when performing an update of the client. This could lead to remote code execution in an elevated privileged context. 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-2021-33907)

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