Zoom Client < 5.10.0 Attack Chain Vulnerabilities

critical Nessus Plugin ID 161760

Language:

Synopsis

The remote host has an application installed that is affected by multiple vulnerabilities.

Description

The version of Zoom Client for Meetings for Windows installed on the remote host is prior to 5.10.0. It is, therefore, affected by multiple vulnerabilities.

 - The Zoom Client for Meetings (for Android, iOS, Linux, MacOS, and Windows) before version 5.10.0 failed to properly parse XML stanzas in XMPP messages. (CVE-2022-22784)
- The Zoom Client for Meetings (for Android, iOS, Linux, MacOS, and Windows) before version 5.10.0 failed to properly constrain client session cookies to Zoom domains.
 (CVE-2022-22785)
- The Zoom Client for Meetings for Windows before version 5.10.0 and Zoom Rooms for Conference Room for Windows before version 5.10.0, fails to properly check the installation version during the update process. (CVE-2022-22786)
- The Zoom Client for Meetings (for Android, iOS, Linux, macOS, and Windows) before version 5.10.0 fails to properly validate the hostname during a server switch request. (CVE-2022-22787)

Taken together, these vulnerabilities allow a unauthenticated, remote attacker can exploit this, via stringing these vulnerabilities together with a MitM attack, to cause Remote Code Execution without any user interaction.

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 5.10.0 or later.
