Detailsinfo

A vulnerability classified as critical has been found in QEMU up to 4.0.0 (Virtualization Software). Affected is an unknown function of the component QMP guest_exec Command Handler. The manipulation with an unknown input leads to a os command injection vulnerability. CWE is classifying the issue as CWE-78. The product constructs all or part of an OS command using externally-influenced input from an upstream component, but it does not neutralize or incorrectly neutralizes special elements that could modify the intended OS command when it is sent to a downstream component. This is going to have an impact on confidentiality, integrity, and availability. CVE summarizes:

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.

The weakness was released 06/24/2019. This vulnerability is traded as CVE-2019-12929 since 06/20/2019. The exploitability is told to be easy. It is possible to launch the attack remotely. The exploitation doesn't require any form of authentication. There are neither technical details nor an exploit publicly available. The current price for an exploit might be approx. USD $5k-$25k (estimation calculated on 03/06/2025). The MITRE ATT&CK project declares the attack technique as T1202.
