Improper access control in Zoom Desktop Client for Windows, Zoom VDI Client for Windows, and Zoom SDKs for Windows before version 5.16.10 may allow an authenticated user to conduct an escalation of privilege via local access.

Path traversal in Zoom Desktop Client for Windows, Zoom VDI Client for Windows, and Zoom SDKs for Windows may allow an authenticated user to conduct an escalation of privilege via network access.

Improper authorization in some Zoom clients may allow an authorized user to conduct an escalation of privilege via network access.

Improper input validation in Zoom Desktop Client for Windows before 5.14.7 may allow an unauthenticated user to enable an escalation of privilege via network access.

Exposure of sensitive information in Zoom Client SDK's before 5.15.5 may allow an authenticated user to enable a denial of service via network access.

Improper neutralization of special elements in Zoom Desktop Client for Windows and Zoom VDI Client before 5.15.2 may allow an unauthenticated user to enable an escalation of privilege via network access.

Improper privilege management in Zoom Desktop Client for Windows and Zoom Rooms for Windows before 5.15.5 may allow an authenticated user to enable an information disclosure via local access.

Insufficient verification of data authenticity in Zoom Desktop Client for Windows before 5.14.5 may allow an authenticated user to enable an escalation of privilege via network access.

Improper access control in Zoom Rooms for Windows before version 5.15.0 may allow an authenticated user to enable an escalation of privilege via local access.

Untrusted search path in the installer for Zoom Rooms for Windows before version 5.15.0 may allow an authenticated user to enable an escalation of privilege via local access.

Path traversal in Zoom Desktop Client for Windows before 5.14.7 may allow an unauthenticated user to enable an escalation of privilege via network access.

Improper input validation in the Zoom for Windows, Zoom Rooms, Zoom VDI Windows Meeting clients before 5.14.0 may allow an authenticated user to potentially enable an escalation of privilege via network access.

Improper privilege management in Zoom for Windows, Zoom Rooms for Windows, and Zoom VDI for Windows clients before 5.14.0 may allow an authenticated user to potentially enable an escalation of privilege via local access. Users may potentially utilize higher level system privileges maintained by the Zoom client to spawn processes with escalated privileges.

Insecure temporary file in the installer for Zoom Rooms for Windows before version 5.15.0 may allow an authenticated user to enable an escalation of privilege via local access.

Improper input validation in the Zoom Desktop Client for Windows before version 5.15.0 may allow an unauthorized user to enable an escalation of privilege via network access.

Insufficient verification of data authenticity in Zoom for Windows clients before 5.14.0 may allow an authenticated user to potentially enable an escalation of privilege via network access.

Zoom for Windows clients prior to 5.14.0 contain an improper restriction of operations within the bounds of a memory buffer vulnerability. A malicious user may alter protected Zoom Client memory buffer potentially causing integrity issues within the Zoom Client.

Zoom clients prior to 5.13.5 contain an improper trust boundary implementation vulnerability. If a victim saves a local recording to an SMB location and later opens it using a link from Zoom’s web portal, an attacker positioned on an adjacent network to the victim client could set up a malicious SMB server to respond to client requests, causing the client to execute attacker controlled executables. This could result in an attacker gaining access to a user's device and data, and remote code execution.

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 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.

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.

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.

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.

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.
