Exploitation Probability (EPSS)

Low risk

2th percentile - higher than 2% of all known CVEs

Summary

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.

Risk Assessment

The organization faces risks of data leakage, system disruption, or machine takeover by an unprivileged local user. An attacker can read confidential files, corrupt disk data, or gain elevated privileges.

Recommendation

Immediately update EaseUs Todo Backup to the latest version containing a fixed eudskacs.sys driver with proper privilege validation. Until the update, restrict local system access to untrusted users.
