CVSS measures technical severity, not the likelihood of an attack.

Known exploitation

Not listed in the checked CISA KEV catalog

Absence from CISA KEV does not rule out attacks.

Public exploit

Exploit reference published

Source-linked evidence; not proof of attacks in the wild or independent validation.

Remediation

Source guidance available

Review the recorded instructions. Guidance may be a workaround rather than a fixed version.

What this means

A local attacker with process inspection access can expose guest VM credentials in cockpit-machines. The vulnerability occurs when credentials are passed as a JSON command-line argument during VM creation. Exposure is limited to the installation workflow period.

Summarized by @cf/meta/llama-3.3-70b-instruct-fp8-fast. Verify details against the original sources.

Automatic dependency matching is unavailable for this record. Use the product evidence and publisher’s instructions to check your installation.

What to do

Compare your installed product and version with the affected versions above. A matching product name alone does not confirm exposure.

Exposure can be reduced by avoiding VM creation or installation flows that supply rootPassword or userPassword while untrusted local users are active on the host, and by using an alternative provisioning method where one is available. Restricting cross-user process inspection on the host, for example by hardening /proc visibility with the hidepid mount option, also limits the ability of other local users to read the install_machine.py command line. These measures reduce the exposure window but do not remove the underlying issue of credentials being passed in process arguments; they should be treated as temporary risk reduction until a fixed cockpit-machines package is available.

Original source description

Read the full publisher description

A flaw was found in cockpit-machines. This vulnerability allows a local attacker with the ability to inspect running processes to expose sensitive guest virtual machine (VM) credentials, such as rootPassword and userPassword. This occurs when the install_machine.py script passes these credentials as a JSON command-line argument during VM creation or installation. The exposure is limited to the period when the installation workflow is active and depends on host process-visibility policies.
