This vulnerability affects Foreman's network interface handling.\nThe caller needs an account with a search-limited host permission and permission to view that domain or subnet. That account is not an unrestricted administrator. Hence, Low Privileges are required.\nWith successful exploitation, the caller can read interface fields for hosts outside their search, including the name, addresses, MAC address, FQDN, and host name. The response does not include the BMC password. With a search-limited edit permission, the caller can change interface fields on those hosts, such as the IPv4 address. The change is limited to interface records. It does not grant control of Foreman.\n```\nThe vulnerable code was introduced in Foreman 1.7.0 when domain and subnet nested interface routes were added. All Foreman versions from 1.7.0 onward contain this code. The host-nested interface route was corrected in Foreman 1.12.1 and 1.11.4 and is outside of this flaw.\n```", "threat_severity": "Moderate"}
