CVE-2018-20621 HIGH

An issue was discovered in Microvirt MEmu 6.0.6. The MemuService.exe service binary is vulnerable to local privilege escalation through binary planting due to insecure permissions set at install time. This allows code to be run as NT AUTHORITY/SYSTEM.

CVE-2019-14514 HIGH

An issue was discovered in Microvirt MEmu all versions prior to 7.0.2. A guest Android operating system inside the MEmu emulator contains a /system/bin/systemd binary that is run with root privileges on startup (this is unrelated to Red Hat's systemd init program, and is a closed-source proprietary tool that seems to be developed by Microvirt). This program opens TCP port 21509, presumably to receive installation-related commands from the host OS. Because everything after the installer:uninstall command is concatenated directly into a system() call, it is possible to execute arbitrary commands by supplying shell metacharacters.
