Relative path traversal in the Zoom Client SDK before version 5.15.0 may allow an unauthorized user to enable information disclosure 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.

Exposure of information intended to be encrypted by some Zoom clients may lead to disclosure of sensitive information.

Buffer copy without checking size of input in Zoom Meeting SDK before 5.13.0 may allow an authenticated user to potentially enable a denial of service via local access. This issue may result in the Zoom Meeting SDK to crash and need to be restarted.

Exposure of resource to wrong sphere in Zoom for Windows and Zoom for MacOS clients before 5.14.10 may allow an authenticated user to potentially enable information disclosure via network access.

Improper input validation in the installer for Zoom for Windows clients before 5.14.0 may allow an authenticated user to potentially enable an escalation of privilege via local 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.

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 VDI client installer prior to 5.14.0 contains an improper access control vulnerability. A malicious user may potentially delete local files without proper permissions.

Zoom for Windows clients prior to 5.13.5 contain an improper verification of cryptographic signature vulnerability. A malicious user may potentially downgrade Zoom Client components to previous versions.

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 for MacOSclients prior to 5.14.0 contain an improper access control vulnerability. A malicious user may be able to delete/replace Zoom Client files potentially causing a loss of integrity and availability to 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 Client for IT Admin macOS installers before version 5.13.5 contain a local privilege escalation vulnerability. A local low-privileged user could exploit this vulnerability in an attack chain during the installation process to escalate their privileges to privileges to root.

Zoom Client for IT Admin Windows installers before version 5.13.5 contain a local privilege escalation vulnerability. A local low-privileged user could exploit this vulnerability in an attack chain during the installation process to escalate their privileges to the SYSTEM user.

Zoom clients before version 5.13.5 contain a STUN parsing vulnerability. A malicious actor could send specially crafted UDP traffic to a victim Zoom client to remotely cause the client to crash, causing a denial of service.

Zoom clients before version 5.13.5 contain a STUN parsing vulnerability. A malicious actor could send specially crafted UDP traffic to a victim Zoom client to remotely cause the client to crash, causing a denial of service.
