CVE-2022-3421 | Privilege escalation in Google Drive for Desktop on MacOS

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

Base score Version Severity Vector Exploitability Impact Score source
5.6 3.1 MEDIUM
CVSS:3.1/AV:L/AC:L/PR:L/UI:R/S:U/C:N/I:H/A:L Click to expand
Attack vector (AV:L)
They already need access on the box, or another person has to do something wrong; it’s not a remote drive-by.
Attack complexity (AC:L)
Once they can reach the bug, pulling it off is straightforward—no weird race conditions or rare setup.
Privileges required (PR:L)
A normal user session is enough; they don’t have to be admin.
User interaction (UI:R)
A real person has to do something—click, install, enable—otherwise it doesn’t land.
Scope (S:U)
Damage stays in the same “trust bubble” as the broken component—no big spill into unrelated systems.
Confidentiality (C:N)
Doesn’t really leak secrets in a meaningful way.
Integrity (I:H)
They could widely tamper with or forge data—trust in the data is badly hurt.
Availability (A:L)
Might cause slowdowns, glitches, or partial disruption—not a full brick.
