NVD Description

Note: Versions mentioned in the description apply only to the upstream idm:client/ipa-client package and not the idm:client/ipa-client package as distributed by RHEL. See How to fix? for RHEL:8 relevant fixed versions and status.

If kdcproxy receives a request for a realm which does not have server addresses defined in its configuration, by default, it will query SRV records in the DNS zone matching the requested realm name. This creates a server-side request forgery vulnerability, since an attacker could send a request for a realm matching a DNS zone where they created SRV records pointing to arbitrary ports and hostnames (which may resolve to loopback or internal IP addresses). This vulnerability can be exploited to probe internal network topology and firewall rules, perform port scanning, and exfiltrate data. Deployments where the "use_dns" setting is explicitly set to false are not affected.
