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 •
