Zoom Client Installer Local Privilege Escalation

Published Sep 27, 2021 · Updated Sep 16, 2024 · Assigned by Zoom

It was discovered that the installation packages of the Zoom Client for Meetings for MacOS (Standard and for IT Admin) installation before version 5.2.0, Zoom Client Plugin for Sharing iPhone/iPad before version 5.2.0, and Zoom Rooms for Conference before version 5.1.0, copy pre- and post- installation shell scripts to a user-writable directory.
