Dual DHCP DNS Server 8.01 improperly accepts and caches UDP DNS responses without validating that the response originates from a legitimate configured upstream DNS server. The implementation matches responses primarily by TXID and inserts results into the cache, enabling a remote attacker to inject forged responses and poison the DNS cache, potentially redirecting victims to attacker-controlled destinations.
