An attacker who is able to send and receive messages to an authoritative DNS server and who has knowledge of a valid TSIG key name for the zone and service being targeted may be able to manipulate BIND into accepting an unauthorized dynamic update. Affects BIND 9.4.0->9.8.8, 9.9.0->9.9.10-P1, 9.10.0->9.10.5-P1, 9.11.0->9.11.1-P1, 9.9.3-S1->9.9.10-S2, 9.10.5-S1->9.10.5-S2.
CWE-ID: CWE Name: A server that relies solely on TSIG keys with no other address-based ACL protection could be vulnerable to malicious zone content manipulation using this technique.
Note that the local update policy (configured with "update-policy local;" in named.conf) implicitly defines a key with a known key name (local-ddns) and default algorithm and no IP-based access controls on the zone updates. In conjunction with this failure in TSIG verification, "update-policy local" is potentially very dangerous. Source: ISC
