Zoom Client for Meetings < 5.3.2 Vulnerability (ZSB-21004)

high Nessus Plugin ID 168818


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


The version of Zoom Client for Meetings installed on the remote host is prior to 5.3.2. It is, therefore, affected by a vulnerability as referenced in the ZSB-21004 advisory.

- A user-writable directory created during the installation of the Zoom Client for Meetings for Windows version prior to version 5.3.2 can be redirected to another location using a junction. This would allow an attacker to overwrite files that a limited user would otherwise be unable to modify. 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-2021-34408)

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