Kerentanan Insufficient Verification of Data Authenticity pada nlnetlabs unbound. Skor CVSS 3.1 6.5 (Medium) menurut nlnetlabs.nl.
In NLnet Labs Unbound 1.7.0 up to and including 1.25.1, when an auth/rpz zone has a configured primary hostname that resolves to BOGUS A/AAAA, it is still considered as a possible XFR endpoint. A malicious actor that can spoof the hostname's A/AAAA record (no valid RRSIG required) becomes the zone's XFR primary and can replaces the entire zone/the resolver's entire response policy.
