| Título | EaseUS Partition Master Kernel Driver epmntdrv.sys 14.5 Local Privilege Escapation |
|---|
| Descrição | EaseUS Partition Master installs and loads epmntdrv.sys, which exposes a legacy device path of the form \\.\EPMNTDRV\<disk>. A standard local user can open this device, bind it to a caller-selected physical disk, and issue raw reads and writes through the driver.
In the validation below, a standard user at Medium Integrity could not directly read or write an administrator-only flag file on a temporary VHD and could not directly open \\.\PhysicalDrive1. The same user opened \\.\EPMNTDRV\1, read the protected file's NTFS data clusters, then overwrote those same clusters with a marker. Administrator readback from the protected file confirmed the write.
An unprivileged user can exploit arbitrary read/write primitives over protected file resources to achieve local privilege escalation. |
