Zoom Client Application Chat Code Snippet Remote Code Execution Vulnerability [CVE-2020-6110]

CVE Number – CVE-2020-6110

An exploitable partial path traversal vulnerability exists in the way Zoom Client version 4.6.10 processes messages including shared code snippets.

A specially crafted chat message can cause an arbitrary binary planting which could be abused to achieve arbitrary code execution. An attacker needs to send a specially crafted message to a target user or a group to trigger this vulnerability.

For the most severe effect, target user interaction is required.
