Zoom Desktop Client for Windows, Zoom VDI Client for Windows, and Zoom Meeting SDK for Windows - Improper Input Validation

Improper input validation in Zoom Desktop Client for Windows, Zoom VDI Client for Windows, and Zoom Meeting SDK for Windows may allow an unauthenticated user to conduct an escalation of privilege via network access.

Zoom Clients - Untrusted Search Path

Untrusted search path in some Zoom 32 bit Windows clients may allow an authenticated user to conduct an escalation of privilege via local access.

Improper URL parsing in Zoom Clients

The Zoom Client for Meetings (for Android, iOS, Linux, macOS, and Windows) before version 5.12.2 is susceptible to a URL parsing vulnerability. If a malicious Zoom meeting URL is opened, the malicious link may direct the user to connect to an arbitrary network address, leading to additional attacks including session takeovers.

Local Privilege Escalation in Zoom Client Installer for macOS

The Zoom Client for Meetings Installer for macOS (Standard and for IT Admin) before version 5.12.6 contains a local privilege escalation vulnerability. A local low-privileged user could exploit this vulnerability during the install process to escalate their privileges to root.

DLL injection in Zoom Windows Clients

Windows 32-bit versions of the Zoom Client for Meetings before 5.12.6 and Zoom Rooms for Conference Room before version 5.12.6 are susceptible to a DLL injection vulnerability. A local low-privileged user could exploit this vulnerability to run arbitrary code in the context of the Zoom client.

Local information exposure in Zoom Clients

The Zoom Client for Meetings (for Android, iOS, Linux, macOS, and Windows) before version 5.12.6 is susceptible to a local information exposure vulnerability. A failure to clear data from a local SQL database after a meeting ends and the usage of an insufficiently secure per-device key encrypting that database results in a local malicious user being able to obtain meeting information such as in-meeting chat for the previous meeting attended from that local user account.

Local Privilege Escalation in Zoom Rooms Installer for Windows

The Zoom Rooms Installer for Windows prior to 5.12.6 contains a local privilege escalation vulnerability. A local low-privileged user could exploit this vulnerability during the install process to escalate their privileges to the SYSTEM user.

Stack-based buffer overflow in the ZoomLauncher binary in the Zoom client for Linux before 2.0.115900.1201 allows remote attackers to execute arbitrary code by leveraging the zoommtg:// scheme handler.

The ZoomLauncher binary in the Zoom client for Linux before 2.0.115900.1201 does not properly sanitize user input when constructing a shell command, which allows remote attackers to execute arbitrary code by leveraging the zoommtg:// scheme handler.

The ZOOM Cloud Meetings (aka us.zoom.videomeetings) application @7F060008 for Android does not verify X.509 certificates from SSL servers, which allows man-in-the-middle attackers to spoof servers and obtain sensitive information via a crafted certificate.

Zoom Desktop Client for Windows, Zoom VDI Client for Windows, and Zoom Meeting SDK for Windows - Improper Input Validation

Improper input validation in Zoom Desktop Client for Windows, Zoom VDI Client for Windows, and Zoom Meeting SDK for Windows may allow an authenticated user to conduct a disclosure of information via network access.

Insecure key generation for Zoom Rooms for macOS Clients

Zoom Rooms for macOS clients before version 5.11.4 contain an insecure key generation mechanism. The encryption key used for IPC between the Zoom Rooms daemon service and the Zoom Rooms client was generated using parameters that could be obtained by a local low-privileged application. That key can then be used to interact with the daemon service to execute privileged functions and cause a local denial of service.

Local Privilege Escalation in Zoom Rooms for macOS Clients

Zoom Rooms for macOS clients before version 5.11.3 contain a local privilege escalation vulnerability. A local low-privileged user could exploit this vulnerability to escalate their privileges to root.

Local Privilege Escalation in Zoom Rooms for macOS Clients

Zoom Rooms for macOS clients before version 5.11.3 contain a local privilege escalation vulnerability. A local low-privileged user could exploit this vulnerability to escalate their privileges to root.

Path Traversal in Zoom for Android Clients

Zoom for Android clients before version 5.13.0 contain a path traversal vulnerability. A third party app could exploit this vulnerability to read and write to the Zoom application data directory.

Local Privilege Escalation in Zoom Rooms for Windows Clients

The Zoom Rooms Installer for Windows prior to 5.12.6 contains a local privilege escalation vulnerability. A local low-privileged user could exploit this vulnerability during the install process to escalate their privileges to the SYSTEM user.

Local Privilege Escalation in Zoom Rooms for Windows Installers

Zoom Rooms for Windows installers before version 5.13.0 contain a local privilege escalation vulnerability. A local low-privileged user could exploit this vulnerability in an attack chain to escalate their privileges to the SYSTEM user.

Zoom Clients - Business Logic Error

Business logic error in some Zoom clients may allow an authenticated user to conduct information disclosure via network access.

Zoom Workplace Apps - Incorrect Ownership Assignment

Incorrect ownership assignment in some Zoom Workplace Apps may allow a privileged user to conduct an information disclosure via network access.

Zoom Apps for macOS - Symbolic Link Following

Symlink following in the installer for some Zoom apps for macOS before version 6.1.5 may allow an authenticated user to conduct an escalation of privilege via network access.
