- ZSB-21021
- CVE-2021-34425
- Medium
- 4.7
- CVSS:3.1/AV:N/AC:H/PR:N/UI:R/S:C/C:L/I:L/A:N
The Zoom Client for Meetings before version 5.7.3 (for Android, iOS, Linux, macOS, and Windows) contain a server side request forgery vulnerability in the chat’s “link preview” functionality. In versions prior to 5.7.3, if a user were to enable the chat’s “link preview” feature, a malicious actor could trick the user into potentially sending arbitrary HTTP GET requests to URLs that the actor cannot reach directly.
Users can help keep themselves secure by applying current updates or downloading the latest Zoom software with all current security updates from https://zoom.us/download.
- All Zoom Client for Meetings (for Android, iOS, Linux, macOS, and Windows) before version 5.7.3
