What is CVE-2019-14514?

A vulnerability exists in the MEmu Emulator developed by Microvirt, which affects all versions prior to 7.0.2. Within this emulator, a guest Android operating system runs a proprietary /system/bin/systemd binary with root privileges at startup. This binary opens TCP port 21509, likely to receive commands from the host operating system. The flaw lies in the handling of commands provided to the installer:uninstall directive, allowing attackers to inject shell metacharacters, which could lead to the execution of arbitrary commands on the host system.
