| शीर्षक | EaseUS Partition Master Kernel Driver EUEDKEPM.sys 14.5 Local Privilege Escapation |
|---|
| विवरण | EaseUS Partition Master installs EUEDKEPM.sys, a raw disk forwarding kernel driver that exposes a device path of the form \\.\EUEDKEPM\<disk>. A standard local user can open this device and issue raw reads and writes against a caller-selected physical disk number.
In this validation, a standard user at Medium Integrity could not directly read or write an administrator-only test file and could not directly open the underlying raw disk. The same user then used \\.\EUEDKEPM\1 to read the file's NTFS data clusters from a controlled temporary VHD and to overwrite the same protected file data. Administrator readback confirmed the write marker in the protected file.
This is a local Windows access-control bypass. The driver performs lower-disk I/O in kernel mode and exposes privileged raw disk functionality to an unprivileged caller. An unprivileged user can exploit arbitrary read/write primitives over protected file resources to achieve local privilege escalation. |
