What is CVE-2019-14514?
CVE-2019-14514 is a critical command injection vulnerability in n/a, published on 10 Feb 2020. An attacker can exploit it over the internet without logging in, with no action from the victim.
Official description
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.
Weakness: CWE-78
