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 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 for Windows clients before version 5.13.3, Zoom Rooms for Windows clients before version 5.13.5 and Zoom VDI for Windows clients before 5.13.1 contain an information disclosure vulnerability. A recent update to the Microsoft Edge WebView2 runtime used by the affected Zoom clients, transmitted text to Microsoft’s online Spellcheck service instead of the local Windows Spellcheck. Updating Zoom remediates this vulnerability by disabling the feature. Updating Microsoft Edge WebView2 Runtime to at least version 109.0.1481.0 and restarting Zoom remediates this vulnerability by updating Microsoft’s telemetry behavior.

The Zoom Client for Meetings (for Android, iOS, Linux, macOS, and Windows) before version 5.11.0 are 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 the potential for remote code execution through launching executables from arbitrary paths.

Zoom through 5.5.4 sometimes allows attackers to read private information on a participant's screen, even though the participant never attempted to share the private part of their screen. When a user shares a specific application window via the Share Screen functionality, other meeting participants can briefly see contents of other application windows that were explicitly not shared. The contents of these other windows can (for instance) be seen for a short period of time when they overlay the shared window and get into focus. (An attacker can, of course, use a separate screen-recorder application, unsupported by Zoom, to save all such contents for later replays and analysis.) Depending on the unintentionally shared data, this short exposure of screen contents may be a more or less severe security issue.

An exploitable partial path traversal vulnerability exists in the way Zoom Client version 4.6.10 processes messages including shared code snippets. A specially crafted chat message can cause an arbitrary binary planting which could be abused to achieve arbitrary code execution. An attacker needs to send a specially crafted message to a target user or a group to trigger this vulnerability. For the most severe effect, target user interaction is required.
