CVE-2022-3421Privilege escalation in Google Drive for Desktop on MacOS
Medium 5.6
In plain English
A medium-severity security flaw in Drive for Desktop MacOS from Google LLC. There are no confirmed reports of exploitation so far. The chance it is exploited in the next 30 days is estimated at 0.1% (higher than 2% of all known vulnerabilities).
Official description
An attacker can pre-create the `/Applications/Google\ Drive.app/Contents/MacOS` directory which is expected to be owned by root to be owned by a non-root user. When the Drive for Desktop installer is run for the first time, it will place a binary in that directory with execute permissions and set its setuid bit. Since the attacker owns the directory, the attacker can replace the binary with a symlink, causing the installer to set the setuid bit on the symlink. When the symlink is executed, it will run with root permissions. We recommend upgrading past version 64.0
