CVE-2022-22788Network attack vector

Code execution via uncontrolled DLL search path

Published Jun 15, 2022 · Updated Sep 16, 2024

DLL injection in the Zoom Opener installer before 5.10.3 allows remote authenticated users to execute arbitrary code on a victim's host. The installer searches for a DLL without constraining its load path, allowing an attacker-supplied library to be loaded. Exploitation requires a user without the client installed to download and run the Opener from the Launch Meeting page, after which the injected code runs on that host.
