Descriptions

The Zoom Client for Meetings (for Android, iOS, Linux, MacOS, and Windows) before version 5.10.0 failed to properly parse XML stanzas in XMPP messages. This can allow a malicious user to break out of the current XMPP message context and create a new message context to have the receiving users client perform a variety of actions.This issue could be used in a more sophisticated attack to forge XMPP messages from the server.

Zoom Client for Meetings (para Android, iOS, Linux, MacOS y Windows) versiones anteriores a 5.10.0, no analizaba apropiadamente las estrofas XML en los mensajes XMPP. Esto puede permitir a un usuario malicioso salir del contexto actual del mensaje XMPP y crear un nuevo contexto de mensaje para que el cliente de usuarios receptores lleve a cabo una variedad de acciones. Este problema podría ser usado en un ataque más sofisticado para falsificar mensajes XMPP desde el servidor
