Latest Zoom Security Vulnerabilities
The Zoom IT installer for Windows (ZoomInstallerFull.msi) prior to version 4.6.10 deletes files located in %APPDATA%\Zoom before installing an updated version of the client
CVE-2020-11443
8.1 - High
- May 04, 2020
The Zoom IT installer for Windows (ZoomInstallerFull.msi) prior to version 4.6.10 deletes files located in %APPDATA%\Zoom before installing an updated version of the client. Standard users are able to write to this directory, and can write links to other directories on the machine. As the installer runs with SYSTEM privileges and follows these links, a user can cause the installer to delete files that otherwise cannot be deleted by the user.
Incorrect Permission Assignment for Critical Resource
** DISPUTED ** airhost.exe in Zoom Client for Meetings 4.6.11 uses the SHA-256 hash of 0123425234234fsdfsdr3242 for initialization of an OpenSSL EVP AES-256 CBC context
CVE-2020-11876
7.5 - High
- April 17, 2020
** DISPUTED ** airhost.exe in Zoom Client for Meetings 4.6.11 uses the SHA-256 hash of 0123425234234fsdfsdr3242 for initialization of an OpenSSL EVP AES-256 CBC context. NOTE: the vendor states that this initialization only occurs within unreachable code.
Use of Hard-coded Credentials
** DISPUTED ** airhost.exe in Zoom Client for Meetings 4.6.11 uses 3423423432325249 as the Initialization Vector (IV) for AES-256 CBC encryption
CVE-2020-11877
7.5 - High
- April 17, 2020
** DISPUTED ** airhost.exe in Zoom Client for Meetings 4.6.11 uses 3423423432325249 as the Initialization Vector (IV) for AES-256 CBC encryption. NOTE: the vendor states that this IV is used only within unreachable code.
Inadequate Encryption Strength
Zoom Client for Meetings through 4.6.9 uses the ECB mode of AES for video and audio encryption
CVE-2020-11500
7.5 - High
- April 03, 2020
Zoom Client for Meetings through 4.6.9 uses the ECB mode of AES for video and audio encryption. Within a meeting, all participants use a single 128-bit key.
Use of a Broken or Risky Cryptographic Algorithm
Zoom Client for Meetings through 4.6.8 on macOS copies runwithroot to a user-writable temporary directory during installation, which
CVE-2020-11469
7.8 - High
- April 01, 2020
Zoom Client for Meetings through 4.6.8 on macOS copies runwithroot to a user-writable temporary directory during installation, which allows a local process (with the user's privileges) to obtain root access by replacing runwithroot.
Improper Privilege Management
Zoom Client for Meetings through 4.6.8 on macOS has the disable-library-validation entitlement, which
CVE-2020-11470
3.3 - Low
- April 01, 2020
Zoom Client for Meetings through 4.6.8 on macOS has the disable-library-validation entitlement, which allows a local process (with the user's privileges) to obtain unprompted microphone and camera access by loading a crafted library and thereby inheriting Zoom Client's microphone and camera access.
AuthZ
The Zoom Client before 4.4.53932.0709 on macOS allows remote code execution, a different vulnerability than CVE-2019-13450
CVE-2019-13567
8.8 - High
- July 12, 2019
The Zoom Client before 4.4.53932.0709 on macOS allows remote code execution, a different vulnerability than CVE-2019-13450. If the ZoomOpener daemon (aka the hidden web server) is running, but the Zoom Client is not installed or can't be opened, an attacker can remotely execute code with a maliciously crafted launch URL. NOTE: ZoomOpener is removed by the Apple Malware Removal Tool (MRT) if this tool is enabled and has the 2019-07-10 MRTConfigData.
Improper Input Validation
In the Zoom Client before 4.4.2 on macOS, remote attackers can cause a denial of service (continual focus grabs)
CVE-2019-13449
6.5 - Medium
- July 09, 2019
In the Zoom Client before 4.4.2 on macOS, remote attackers can cause a denial of service (continual focus grabs) via a sequence of invalid launch?action=join&confno= requests to localhost port 19421.
Improper Input Validation
In the Zoom Client through 4.4.4 and RingCentral 7.0.136380.0312 on macOS, remote attackers
CVE-2019-13450
6.5 - Medium
- July 09, 2019
In the Zoom Client through 4.4.4 and RingCentral 7.0.136380.0312 on macOS, remote attackers can force a user to join a video call with the video camera active. This occurs because any web site can interact with the Zoom web server on localhost port 19421 or 19424. NOTE: a machine remains vulnerable if the Zoom Client was installed in the past and then uninstalled. Blocking exploitation requires additional steps, such as the ZDisableVideo preference and/or killing the web server, deleting the ~/.zoomus directory, and creating a ~/.zoomus plain file.
Authorization
Zoom clients on Windows (before version 4.1.34814.1119)
CVE-2018-15715
9.8 - Critical
- November 30, 2018
Zoom clients on Windows (before version 4.1.34814.1119), Mac OS (before version 4.1.34801.1116), and Linux (2.4.129780.0915 and below) are vulnerable to unauthorized message processing. A remote unauthenticated attacker can spoof UDP messages from a meeting attendee or Zoom server in order to invoke functionality in the target client. This allows the attacker to remove attendees from meetings, spoof messages from users, or hijack shared screens.
