Summary

The cockpit-machines component is affected in Red Hat Enterprise Linux 8, 9 and 10. When saving VNC console settings, the configured password is passed as a command-line argument to a system utility, which is CWE-214. A local unprivileged attacker on a host that allows cross-user process inspection can read the password from the process list while another user modifies settings, which allows unauthorized access to the guest virtual machine's graphical console.

Description from the CNA

A flaw was found in cockpit-machines. When saving Virtual Network Computing (VNC) console settings, the configured password is passed directly as a command-line argument to an underlying system utility. A local unprivileged attacker on a host that allows cross-user process inspection could read the exposed password from the process list while another user modifies settings. This credential disclosure can allow unauthorized access to the guest virtual machine's graphical console.
