| عنوان | AOMEI AOMEI Backupper Kernel Driver amwrtdrv.sys 8.3.0 Local Privilege Escapation |
|---|
| الوصف | AOMEI Backupper 8.3.0 installs and auto-loads the signed kernel driver amwrtdrv.sys. The driver exposes a user-reachable raw disk forwarding interface at \\.\amwrtdrv\Partition0\DISK<N>.
A standard, non-administrative user can use this interface to send read and write requests to a disk device even when Windows denies the same user direct access to \\.\PhysicalDrive<N> and to protected files stored on that disk. In the proof below, the standard user could not read or modify an administrator-only flag file on a temporary VHD, but could read and overwrite that file's NTFS data clusters through the AOMEI driver.
An unprivileged user can exploit arbitrary read/write primitives over protected file resources to achieve local privilege escalation. |
