| 标题 | AOMEI AOMEI Partition Assistant Kernel Driver ampa10.sys 10.10.1 Local Privilege Escapation |
|---|
| 描述 | ampa10.sys, shipped with AOMEI Partition Assistant Standard 10.10.1, exposes the \\.\wowrt device to a standard local user and forwards file read/write requests to the underlying disk stack. The forwarded requests are issued from kernel mode, so the normal Windows access check that prevents a standard user from opening \\.\PhysicalDriveN is bypassed.
In a controlled proof, a standard Medium Integrity user could not open a temporary VHD-backed physical disk directly. The same user then wrote a unique 512-byte marker to that disk through \\.\wowrt\Partition0\DISK1, read it back through the driver, and an Administrator confirmed the marker by directly reading \\.\PhysicalDrive1 at the same offset.
An unprivileged user can exploit arbitrary read/write primitives over protected file resources to achieve local privilege escalation. |
