| शीर्षक | IM-Magic Partition Resizer Kernel Driver MDA_NTDRV.sys 7.9.0 Local Privilege Escapation |
|---|
| विवरण | IM-Magic Partition Resizer Free Portable includes MDA_NTDRV.sys, a raw disk forwarding driver that exposes \\.\MDA_NTDRV\<disk>. A standard local user can open this device and perform raw reads and writes against a caller-selected physical disk number.
In the validation below, the standard user could not directly read or write an administrator-only flag file and could not directly open the underlying raw disk. The same user then read the flag's NTFS data clusters through \\.\MDA_NTDRV\1, and also overwrote those clusters through the driver. Administrator readback confirmed that the protected flag file content changed to the attacker's marker.
An unprivileged user can exploit arbitrary read/write primitives over protected file resources to achieve local privilege escalation. |
