Description

Docker Desktop for Windows before 4.6 allows attackers to overwrite any file through the windowscontainers/start dockerBackendV2 API by controlling the data-root field inside the DaemonJSON field in the WindowsContainerStartRequest class. This allows exploiting a symlink vulnerability in ..\dataRoot\network\files\local-kv.db because of a TOCTOU race condition.

Affected products

• Docker Desktop: before 4.6.0 — fixed in 4.6.0

How to fix

Upgrade to a fixed version: Docker Desktop 4.6.0. Check the vendor advisory for mitigations.
