CVE-2019-13567
https://notcve.org/view.php?id=CVE-2019-13567
The Zoom Client before 4.4.53932.0709 on macOS allows remote code execution, a different vulnerability than CVE-2019-13450. If the ZoomOpener daemon (aka the hidden web server) is running, but the Zoom Client is not installed or can't be opened, an attacker can remotely execute code with a maliciously crafted launch URL. NOTE: ZoomOpener is removed by the Apple Malware Removal Tool (MRT) if this tool is enabled and has the 2019-07-10 MRTConfigData. El Cliente Zoom anterior a versión 4.4.2 en macOS, permite la ejecución de código remota, una vulnerabilidad diferente de CVE-2019-13450. Si el demonio ZoomOpener (también conocido como el servidor web hidden) se ejecuta, pero el Cliente Zoom no está instalado o no se puede abrir, un atacante puede ejecutar el código de remotamente con una URL de inicio maliciosamente diseñada. • https://gist.github.com/wbowling/13f9f90365c171806b9ffba2c841026b https://support.zoom.us/hc/en-us/articles/201361963-New-Updates-for-Mac-OS https://twitter.com/JLLeitschuh/status/1149420685405708295 https://twitter.com/JLLeitschuh/status/1149422543658520578 https://twitter.com/riskybusiness/status/1149125147019767814 https://twitter.com/wcbowling/status/1149457231504498689 https://twitter.com/wcbowling/status/1166998107667619841 • CWE-78: Improper Neutralization of Special Elements used in an OS Command ('OS Command Injection') •
CVE-2019-13450
https://notcve.org/view.php?id=CVE-2019-13450
In the Zoom Client through 4.4.4 and RingCentral 7.0.136380.0312 on macOS, remote attackers can force a user to join a video call with the video camera active. This occurs because any web site can interact with the Zoom web server on localhost port 19421 or 19424. NOTE: a machine remains vulnerable if the Zoom Client was installed in the past and then uninstalled. Blocking exploitation requires additional steps, such as the ZDisableVideo preference and/or killing the web server, deleting the ~/.zoomus directory, and creating a ~/.zoomus plain file. En el Cliente Zoom hasta versión 4.4.4 y RingCentral versión 7.0.136380.0312 en macOS, los atacantes remotos pueden forzar a un usuario a unirse a una llamada de video con la cámara de video activa. • http://www.securityfocus.com/bid/109082 https://assets.zoom.us/docs/pdf/Zoom+Response+Video-On+Vulnerability.pdf https://blog.zoom.us/wordpress/2019/07/08/response-to-video-on-concern https://bugs.chromium.org/p/chromium/issues/detail?id=951540 https://medium.com/%40jonathan.leitschuh/zoom-zero-day-4-million-webcams-maybe-an-rce-just-get-them-to-visit-your-website-ac75c83f4ef5 https://news.ycombinator.com/item?id=20387298 https://twitter.com/moreati/status/1148548799813640193 https:// • CWE-862: Missing Authorization •
CVE-2019-13449
https://notcve.org/view.php?id=CVE-2019-13449
In the Zoom Client before 4.4.2 on macOS, remote attackers can cause a denial of service (continual focus grabs) via a sequence of invalid launch?action=join&confno= requests to localhost port 19421. En el Cliente Zoom anterior a versión 4.4.2 en macOS, los atacantes remotos pueden causar una denegación de servicio (captura de enfoque continua) por medio de una secuencia de peticiones invalidas launch?action=join&confno= en el puerto host local 19421. • https://assets.zoom.us/docs/pdf/Zoom+Response+Video-On+Vulnerability.pdf https://blog.zoom.us/wordpress/2019/07/08/response-to-video-on-concern https://bugs.chromium.org/p/chromium/issues/detail?id=951540 https://medium.com/%40jonathan.leitschuh/zoom-zero-day-4-million-webcams-maybe-an-rce-just-get-them-to-visit-your-website-ac75c83f4ef5 https://twitter.com/zoom_us/status/1148710712241295361 • CWE-20: Improper Input Validation •
CVE-2018-15715
https://notcve.org/view.php?id=CVE-2018-15715
Zoom clients on Windows (before version 4.1.34814.1119), Mac OS (before version 4.1.34801.1116), and Linux (2.4.129780.0915 and below) are vulnerable to unauthorized message processing. A remote unauthenticated attacker can spoof UDP messages from a meeting attendee or Zoom server in order to invoke functionality in the target client. This allows the attacker to remove attendees from meetings, spoof messages from users, or hijack shared screens. Los clientes de Zoom en Windows (antes de la versión 4.1.34814.1119), Mac OS (antes de la versión 4.1.34801.1116) y Linux (2.4.129780.0915 y anteriores) son vulnerables al procesamiento no autorizado de imágenes. Un atacante remoto no autenticado puede suplantar los mensajes UDP de un asistente a la reunión o de un servidor de Zoom para invocar funcionalidades en el cliente objetivo. • https://www.tenable.com/security/research/tra-2018-40 • CWE-20: Improper Input Validation CWE-290: Authentication Bypass by Spoofing •
CVE-2017-15049 – Zoom Linux Client 2.0.106600.0904 - Command Injection
https://notcve.org/view.php?id=CVE-2017-15049
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. El binario ZoomLauncher en el cliente Zoom para Linux en versiones anteriores a la 2.0.115900.1201 no sanea adecuadamente las entradas de usuarios al construir un comando shell, lo que permite que los atacantes remotos ejecuten código arbitrario aprovechando el controlador de esquemas zoommtg://. The binary /opt/zoom/ZoomLauncher is vulnerable to command injection because it uses user input to construct a shell command without proper sanitization. The client registers a scheme handler (zoommtg://) and this makes possible to trigger the vulnerability remotely. Version 2.0.106600.0904 is affected. • https://www.exploit-db.com/exploits/43354 http://packetstormsecurity.com/files/145453/Zoom-Linux-Client-2.0.106600.0904-Command-Injection.html http://seclists.org/fulldisclosure/2017/Dec/47 https://github.com/convisoappsec/advisories/blob/master/2017/CONVISO-17-003.txt • CWE-78: Improper Neutralization of Special Elements used in an OS Command ('OS Command Injection') •
