One server cookie obtained through a given proxy node therefore validates for every PROXYv2-declared source behind that node. On a UDP+proxy-protocol front, an off-path attacker can harvest one cookie with a single legitimate query, then replay it under any spoofed source and pass DNS Cookie checks that were deployed to defeat this in the first place.</p> <p><strong>Affected:</strong> NLnet Labs Unbound</p> <p>In NLnet Labs Unbound 1.18.0 up to and including 1.25.1, when Unbound listens on a &#39;proxy-protocol-port&#39; interface with &#39;answer-cookie: yes&#39;, the RFC 9018 server-cookie SipHash is computed over the proxy&#39;s wire address instead of the PROXYv2-declared client.
