One of the flaws allowed for remote code execution in Zoom

Zoom has patched several security vulnerabilities, including a high-severity one that could allow attackers to remotely execute code on the target endpoint.
Tracked as CVE-2022-22786, the flaw revolves around the fact that Zoom’s server, and that of the client, use different XML parsing libraries, and as a result, XMPP messages get parsed differently by the two. It’s only found on Windows devices.
By sending a specific message, an attacker can force the target client to connect to a middle server, and get an old, 2019 version of Zoom, installed. That helps the attacker launch a more devastating attack.
"The installer for this version is still properly signed, however, it does not do any security checks on the .cab file," the researcher explained. "To demonstrate the impact of the attack, I replaced Zoom.exe in the .cab with a binary that just opens Windows Calculator app and observed Calculator being opened after the 'update' was installed."
