A vulnerability was found in subscription-manager that allows local privilege escalation due to inadequate authorization. The D-Bus interface com.redhat.RHSM1 exposes a significant number of methods to all users that could change the state of the registration. By using the com.redhat.RHSM1.Config.SetAll() method, a low-privileged local user could tamper with the state of the registration, by unregistering the system or by changing the current entitlements. This flaw allows an attacker to set arbitrary configuration directives for /etc/rhsm/rhsm.conf, which can be abused to cause a local privilege escalation to an unconfined root.

Subscription-Manager v1.0 /main.js has a cross-site scripting (XSS) vulnerability in the machineDetail parameter.

It was found that subscription-manager's DBus interface before 1.19.4 let unprivileged user access the com.redhat.RHSM1.Facts.GetFacts and com.redhat.RHSM1.Config.Set methods. An unprivileged local attacker could use these methods to gain access to private information, or launch a privilege escalation attack.

/var/lib/rhsm/cache/entitlementstatus.json and /var/lib/rhsm/facts/facts.json are world readable but contain sensitive information (Red Hat Contract number and hardware serial number, sufficient to authenticate again Red Hat and hardware vendor support) can could be used by an attacker to perform a social engineering attack.
