There is a flaw in convert2rhel. When the --activationkey option is used with convert2rhel, the activation key is subsequently passed to subscription-manager via the command line, which could allow unauthorized users locally on the machine to view the activation key via the process command line via e.g. htop or ps. The specific impact varies upon the subscription, but generally this would allow an attacker to register systems purchased by the victim until discovered; a form of fraud. This could occur regardless of how the activation key is supplied to convert2rhel because it involves how convert2rhel provides it to subscription-manager.

The remote Redhat Enterprise Linux 6 host has a package installed that is affected by a vulnerability as referenced in the RHSA-2022:6266 advisory.

    The convert2rhel package provides the Convert2RHEL utility, which performs operating system conversion.
    During the conversion process, Convert2RHEL replaces all RPM packages from the original Linux distribution     with their Red Hat Enteprise Linux versions.

    Security Fix(es):

    * convert2rhel: Activation key passed via command line by code (CVE-2022-0851)

    For more details about the security issue(s), including the impact, a CVSS score, acknowledgments, and     other related information, refer to the CVE page(s) listed in the References section.
