QEMU 4.0.0 and Earlier: QMP Guest_Exec Command OS Command Injection Vulnerability

CVE-2019-12929 · HIGH Severity

AV:N/AC:L/AU:N/C:C/I:C/A:C

The QMP guest_exec command in QEMU 4.0.0 and earlier is prone to OS command injection, which allows the attacker to achieve code execution, denial of service, or information disclosure by sending a crafted QMP command to the listening server. Note: This has been disputed as a non-issue since QEMU's -qmp interface is meant to be used by trusted users. If one is able to access this interface via a tcp socket open to the internet, then it is an insecure configuration issue
