CVE-2023-1490Public exploit

Arbitrary file copy via unrestricted driver IOCTL

Published Mar 18, 2023 · Updated Aug 2, 2024

Improper access control in Max Secure Anti Virus Plus 19.0.2.1 allows local users to copy arbitrary files through SDActMon.sys. The driver's handler for IOCTL 0x220020 accepts a normal user's copy request without enforcing access control on the operation. Low-privilege local access is required, and the resulting file write can replace protected executable content.
