CVSS: 4.3EPSS: 0%CPEs: 1EXPL: 0CVE-2021-28133 – Zoom 5.4.3 (54779.1115) / 5.5.4 (13142.0301) Information Disclosure
https://notcve.org/view.php?id=CVE-2021-28133
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. • http://packetstormsecurity.com/files/161897/Zoom-5.4.3-54779.1115-5.5.4-13142.0301-Information-Disclosure.html http://seclists.org/fulldisclosure/2021/Mar/48 https://thehackernews.com/2021/03/new-zoom-screen-sharing-bug-lets-other.html https://www.syss.de/fileadmin/dokumente/Publikationen/Advisories/SYSS-2020-044.txt https://www.syss.de/pentest-blog/syss-2020-044-sicherheitsproblem-in-screen-sharing-funktionalitaet-von-zoom-cve-2021-28133 https://www.youtube.com/watch?v=SonmmgQlLzg https://zoom& • CWE-200: Exposure of Sensitive Information to an Unauthorized Actor •

https://notcve.org/view.php?id=CVE-2020-6110
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. Se presenta una vulnerabilidad de salto de ruta parcial explotable en la manera en que Zoom Client versión 4.6.10 procesa mensajes que incluyen fragmentos de código compartido. • https://talosintelligence.com/vulnerability_reports/TALOS-2020-1056 • CWE-22: Improper Limitation of a Pathname to a Restricted Directory ('Path Traversal') •

An exploitable path traversal vulnerability exists in the Zoom client, version 4.6.10 processes messages including animated GIFs. A specially crafted chat message can cause an arbitrary file write, which could potentially be abused to achieve arbitrary code execution. An attacker needs to send a specially crafted message to a target user or a group to exploit this vulnerability. Se presenta una vulnerabilidad de salto de ruta explotable en Zoom Client, la versión 4.6.10 procesa mensajes que incluyen GIF animados. Un mensaje de chat especialmente diseñado puede causar una escritura de archivo arbitraria, que podría ser abusada para lograr una ejecución de código arbitraria. • https://talosintelligence.com/vulnerability_reports/TALOS-2020-1055 • CWE-22: Improper Limitation of a Pathname to a Restricted Directory ('Path Traversal') •

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') •

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 •
