Detailed vulnerability description
The disclosed vulnerability allows a remote attacker to perform SSRF attacks.
The vulnerability exists due to insufficient validation of user-supplied input. 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. A remote attacker can probe internal network topology and firewall rules, perform port scanning, and exfiltrate data.
