An issue in Microvirt MEmu Android Emulator 9.2.7.0 allows a local attacker to escalate privileges via the MemuService.exe component.

Memu Play 6.0.7 contains an insecure file permissions vulnerability that allows low-privilege users to escalate privileges by replacing the MemuService.exe executable. Attackers can rename and overwrite MemuService.exe in the installation directory with a malicious executable, which executes with system-level privileges when the service restarts after a computer reboot.

Microvirt MEMU Play 3.7.0 contains an unquoted service path vulnerability in the MEmusvc Windows service that allows local attackers to potentially execute arbitrary code. Attackers can exploit the unquoted binary path to inject malicious executables that will be run with elevated LocalSystem privileges.

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.

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.
