Zoom Client for Meetings < 4.1.34460.1105 Vulnerability (ZSB-18001)

critical Nessus Plugin ID 168824

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 4.1.34460.1105. It is, therefore, affected by a vulnerability as referenced in the ZSB-18001 advisory.

- A vulnerability in the Zoom client could allow a remote, unauthenticated attacker to control meeting functionality such as ejecting meeting participants, sending chat messages, and controlling participant microphone muting. If the attacker was also a valid participant in the meeting and another participant was sharing their desktop screen, the attacker could also take control of that participant's keyboard and mouse. The vulnerability is due to the fact that Zoom's internal messaging pump dispatched both client User Datagram Protocol (UDP) and server Transmission Control Protocol (TCP) messages to the same message handler. An attacker can exploit this vulnerability to craft and send UDP packets which get interpreted as messages processed from the trusted TCP channel used by authorized Zoom servers. Zoom released client updates to address this security vulnerability. Users can help keep themselves secure by applying current updates or downloading the latest Zoom software with all current security updates from https://zoom.us/download . (CVE-2018-15715)

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 4.1.34460.1105 or later.
