The eudskacs.sys driver version 20250328 shipped with EaseUs Todo Backup 1.2.0.1 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, leading to sensitive information disclosure, denial of service, or local privilege escalation.

EaseUS Todo Backup may allow local privilege escalation

EaseUS Todo Backup version 20220111.390 - An omission during installation may allow a local attacker to perform privilege escalation.
