Improper access control in Zoom Rooms for Windows before version 5.15.0 may allow an authenticated user to enable an escalation of privilege via local access.

Zoom clients prior to 5.13.5 contain an improper trust boundary implementation vulnerability. If a victim saves a local recording to an SMB location and later opens it using a link from Zoom’s web portal, an attacker positioned on an adjacent network to the victim client could set up a malicious SMB server to respond to client requests, causing the client to execute attacker controlled executables. This could result in an attacker gaining access to a user's device and data, and remote code execution.

Untrusted search path in some Zoom 32 bit Windows clients may allow an authenticated user to conduct an escalation of privilege via local access.

HP has identified a potential vulnerability in BIOS firmware of some Workstation products. Firmware updates are being released to mitigate these potential vulnerabilities.

During the installation process forZoom Rooms for Conference Room for Windows before version 5.3.0 it is possible to launch Internet Explorer with elevated privileges. If the installer was launched with elevated privileges such as by SCCM this can result in a local privilege escalation.

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. In the affected products listed below, a malicious actor with local access to a user's machine could use this flaw to potentially run arbitrary system commands in a higher privileged context during the installation process.

Zoom Rooms for macOS clients before version 5.11.4 contain an insecure key generation mechanism. The encryption key used for IPC between the Zoom Rooms daemon service and the Zoom Rooms client was generated using parameters that could be obtained by a local low-privileged application. That key can then be used to interact with the daemon service to execute privileged functions and cause a local denial of service.
