Description
EPP.sys in Emsisoft Anti-Malware prior to version 2018.12 allows an attacker to bypass ACLs because Interpreted Device Characteristics lacks FILE_DEVICE_SECURE_OPEN and therefore files and directories "inside" the \\.\EPP device are not properly protected, leading to unintended impersonation or object creation.
