Descriptions

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. This vulnerability has been fixed in version 2018.12 and later.

EPP.sys en Emsisoft Anti-Malware, en versiones anteriores a la 2018.12, permite a los atacantes omitir las ACL debido a que las características de dispositivo interpretado carecen de FILE_DEVICE_SECURE_OPEN y, por tanto, los archivos y directorios "dentro" del dispositivo \\.\EPP no se protegen de manera adecuada, conduciendo a una suplantación o creación de objectos no intencionada. Esta vulnerabilidad se ha solucionado en la versión 2018.12 y posteriores
