2.1
None Local Low Not required Partial None None
Zoom Client for Meetings through 4.6.8 on macOS has the disable-library-validation entitlement, which allows a local process (with the user's privileges) to obtain unprompted microphone and camera access by loading a crafted library and thereby inheriting Zoom Client's microphone and camera access.

7.2
None Local Low Not required Complete Complete Complete
Zoom Client for Meetings through 4.6.8 on macOS copies runwithroot to a user-writable temporary directory during installation, which allows a local process (with the user's privileges) to obtain root access by replacing runwithroot.
6 CVE-2020-11443 732 2020-05-04 2021-07-21
8.5
None Remote Low ??? None Complete Complete
The Zoom IT installer for Windows (ZoomInstallerFull.msi) prior to version 4.6.10 deletes files located in %APPDATA%\Zoom before installing an updated version of the client. Standard users are able to write to this directory, and can write links to other directories on the machine. As the installer runs with SYSTEM privileges and follows these links, a user can cause the installer to delete files that otherwise cannot be deleted by the user.
7 CVE-2020-9767 427 2020-08-14 2020-08-21
7.2
None Local Low Not required Complete Complete Complete
A vulnerability related to Dynamic-link Library (“DLL”) loading in the Zoom Sharing Service would allow an attacker who had local access to a machine on which the service was running with elevated privileges to elevate their system privileges as well through use of a malicious DLL. Zoom addressed this issue, which only applies to Windows users, in the 5.0.4 client release.
8 CVE-2020-6110 22 Exec Code Dir. Trav. 2020-06-08 2020-06-12
6.8
None Remote Medium Not required Partial Partial Partial
An exploitable partial path traversal vulnerability exists in the way Zoom Client version 4.6.10 processes messages including shared code snippets.
