⚡ TL;DR: Go Straight to the Zoom Vulnerability Audit Report

Zoom Client version 4.6.10 has an exploitable path traversal vulnerability (CVE-2020-6109). This is an HTTP exploit that allows an attacker to access personal files as these attacks are executed through web browsers via a manipulated URL. In the Zoom Client Vulnerability, a maliciously tailored chat message will trigger this vulnerability by sending it to the targeted user or group. This can cause an arbitrary file write which could lead to arbitrary code execution.

These messages can include animated GIFs. In Zoom, only Giphy servers were originally meant to be used for this feature but the content from an arbitrary server would be loaded in this case which can be abused to leak even more personal information.

The CVE-2020-6110 vulnerability is almost the same as CVE-2020-6109. When the Zoom Client 4.6.10 version processes a message including shared code snippets, an attacker can send a chat message to the targeted user that will cause an arbitrary binary planting that could be abused to obtain arbitrary code execution.

It allows the attacker to install programs; view, change, or delete data; or create new accounts with full user rights. However, for the most severe effect, target user interaction is required.
