Short explanation
A password disclosure flaw exists in cockpit-machines because saving VNC console settings passes the configured password directly as a command-line argument to an underlying system utility [S0]. A local unprivileged attacker can read this exposed password from the process list [S0].
This credential disclosure can allow unauthorized access to the guest virtual machine's graphical console [S0].
What should be done?
- Follow vendor advisories [S0]

Show the technical text from the sources
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.
