Detailsinfo

A vulnerability classified as critical was found in Red Hat Satellite 6 (unknown version). Affected by this vulnerability is an unknown code block of the component Network Interface. The manipulation with an unknown input leads to a improper authorization vulnerability. The CWE definition for the vulnerability is CWE-285. The product does not perform or incorrectly performs an authorization check when an actor attempts to access a resource or perform an action. As an impact it is known to affect confidentiality, integrity, and availability. The summary by CVE is:

An **incorrect authorization** flaw has been found in **network interface handling** in the **Foreman** package. The domain and subnet interface API checks only that the caller holds a host permission. It does not apply the search limit on that permission, so the request is answered from every interface on the domain or subnet. A low-privileged network attacker or user must already be allowed to view some hosts and to view a domain or subnet shared with other hosts. They can request that domain or subnet's interfaces. The response includes interface records of hosts they are not allowed to view. If the attacker or user is also allowed to edit some hosts, they can submit a change to one of those interfaces. The interface is then saved with that change.
