Recommendation: Plan a near-term fix — a public PoC already exists.
A weakness has been identified in MiniTool Partition Wizard up to 13.6. The affected element is an unknown function in the library pwdrvio.sys of the component Signed Kernel Driver. This manipulation causes improper access controls. The attack can only be executed locally. The exploit has been made available to the public and could be used for attacks. Upgrading to version 13.9 is sufficient to fix this issue. The affected component should be upgraded. The vendor was contacted early about this disclosure.
