Severity

medium5.0

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

Not established by this record

Missing evidence does not mean no public exploit exists.

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 metadata inspection ability can disclose a Red Hat Subscription Management offline token in cockpit-machines. The token is exposed as a command-line argument to a helper script during validation. This may compromise confidentiality.

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

What to do

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

A workaround is available for this issue. Until a fixed package is installed, avoid validating RHSM offline tokens through the Cockpit Machines "Download an OS" / RHEL image download flow on multi-user hosts where untrusted local users can inspect process metadata. As a system-level mitigation, restrict /proc visibility so unprivileged users cannot read other users' process command lines, for example by remounting /proc with the hidepid=2 mount option; this blocks cross-user observation of the helper process arguments that contain the offline token while the validation flow is running. Fixed packages are being released for the affected streams, and updating to a fixed cockpit-machines package once available for your stream resolves the issue.

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 process metadata to disclose a sensitive Red Hat Subscription Management (RHSM) offline token. The token is exposed when it is passed as a command-line argument to a helper script during the token validation process. Successful exploitation could lead to the compromise of confidentiality, as the exposed token can be used to request access tokens.
