What is CVE-2017-15091?

A flaw exists in the API component of PowerDNS Authoritative versions 4.x up to and including 4.0.4 and 3.x up to and including 3.4.11. Specifically, operations that affect the server state can still be executed despite the API being set to read-only through the api-readonly configuration. This oversight allows an attacker with valid API credentials to perform actions such as flushing the cache, initiating a zone transfer, or sending a NOTIFY, which may compromise the server's integrity and operational security.
