Zoom Client for Meetings < 4.4.5 Vulnerability (ZSB-19002)

medium Nessus Plugin ID 168819

Language:

Synopsis

The remote host has an application installed that is affected by a vulnerability.

Description

The version of Zoom Client for Meetings installed on the remote host is prior to 4.4.5. It is, therefore, affected by a vulnerability as referenced in the ZSB-19002 advisory.

 - A vulnerability in the macOS Zoom and RingCentral clients could allow a remote, unauthenticated attacker to force a user to join a video call with the video camera active. The vulnerability is due to insufficient authorization controls to check which systems may communicate with the local Zoom Web server running on port 19421. An attacker could exploit this vulnerability by creating a malicious website that causes the Zoom client to automatically join a meeting set up by the attacker. Zoom implemented a new Video Preview dialog that is presented to the user before joining a meeting in Client version 4.4.5 published July 14, 2019. This dialog enables the user to join the meeting with or without video enabled and requires the user to set their desired default behavior for video. Zoom urges customers to install the latest Zoom Client release available at https://zoom.us/download. (CVE-2019-13450)

Note that Nessus has not tested for this issue but has instead relied only on the application's self-reported version number.

Solution

Upgrade to Zoom Client for Meetings 4.4.5 or later.
