Improper Trust Boundary Implementation Vulnerability in Zoom Clients Prior to 5.13.5

CVE-2023-28597 · HIGH Severity

CVSS:3.1/AV:A/AC:H/PR:N/UI:N/S:U/C:H/I:H/A:H

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.
