When api-config-dir is set to a non-empty value, which is not the case by
default, the API in PowerDNS Recursor 4.x up to and including 4.0.6 and 3.x
up to and including 3.7.4 allows an authorized user to update the
Recursor’s ACL by adding and removing netmasks, and to configure forward
zones. It was discovered that the new netmask and IP addresses of forwarded
zones were not sufficiently validated, allowing an authenticated user to
inject new configuration directives into the Recursor’s configuration.
