"The remote Redhat Enterprise Linux 7 host has packages installed that are affected by a vulnerability as referenced in
the RHSA-2020:4127 advisory.

    Red Hat Satellite is a system management solution that allows organizations to configure and maintain
    their systems without the necessity to provide public Internet access to their servers or other client
    systems. It performs provisioning and configuration management of predefined standard operating
    environments.

    Security Fix(es):

    * foreman: unauthorized cache read on RPM-based installations through local user (CVE-2020-14334)

    This update fixes the following bugs:

    1305773 - Changing Content View of a Content Host needs to better inform the user around client needs
    1666324 - The Host configuration chart shows 100%  even if few hosts are not in sync or reporting.
    1781875 - Red Hat Inventory Uploads does not use proxy
    1793416 - Searching for task requires clicking Search twice to get correct results
    1816464 - Decreased performance in GenerateApplicability in 6.6
    1822564 - vmrc not working 6.7
    1823396 - Hosts are rejected due to mismatch of metadata.json and actual hosts included in satellite
    inventory report
    1829412 - Unable to search by value of certain Hostgroup parameter
    1853466 - RH Cloud -> Insights page does not report error when rh_cloud_token setting is not set
    1854711 - Sync Plan fails with 'uninitialized constant Actions::Foreman::Exception'
    1858307 - CVE-2020-14334 foreman: unauthorized cache read on RPM-based installations through local user
    [rhn_satellite_6.7]
    1862260 - Default job templates are not locked
    1867258 - After upgrading to 6.7 and promoting content, Capsule sync is extremely slow

    Users of Red Hat Satellite are advised to upgrade to these updated packages, which fix these bugs.

Tenable has extracted the preceding description block directly from the Red Hat Enterprise Linux security advisory.

Note that Nessus has not tested for this issue but has instead relied only on the application's self-reported version
number.");
