Technical ContextAI · show details
This vulnerability is classified as Exposure of Sensitive Information (CWE-200), which allows attackers to access sensitive data that should not be disclosed. A flaw was found in podman. The podman machine function (used to create and manage Podman virtual machine containing a Podman process) spawns a gvproxy process on the host system. The gvproxy API is accessible on port 7777 on all IP addresses on the host. If that port is open on the host's firewall, an attacker can potentially use the gvproxy API to forward ports on the host to ports in the VM, making private services on the VM accessible to the network. This issue could be also used to interrupt the host's services by forwarding all ports to the VM. Affected products include: Podman Project Podman, Fedoraproject Fedora, Redhat Enterprise Linux.
