Base vector

AV:L/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H

Name of the Vulnerable Software and Affected Versions: EaseUs Todo Backup version 1.2.0.1

Description: The eudskacs.sys driver version 20250328 fails to properly validate privileges for I/O requests (IRP MJ READ/IRP MJ WRITE) sent to its device object. This allows a local, low-privileged attacker to perform arbitrary raw disk reads and writes, potentially leading to sensitive information disclosure, denial of service, or local privilege escalation.

Recommendations: Update to a newer version of EaseUs Todo Backup that does not include the vulnerable eudskacs.sys driver version 20250328.
