What is CVE-2023-28597?

CVE-2023-28597 is a high-severity code injection vulnerability in Zoom Rooms, published on 27 Mar 2023. It can only be exploited from the same machine or local network, with no action from the victim.

Official description

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.
