Descriptions

An issue has been found in the API component of PowerDNS Authoritative 4.x up to and including 4.0.4 and 3.x up to and including 3.4.11, where some operations that have an impact on the state of the server are still allowed even though the API has been configured as read-only via the api-readonly keyword. This missing check allows an attacker with valid API credentials to flush the cache, trigger a zone transfer or send a NOTIFY.

Se ha descubierto un problema en el componente API de PowerDNS Authoritative 4.x hasta e incluyendo la versión 4.0.4 y en versiones 3.x hasta la 3.4.11, también incluida, donde algunas operaciones que provocan un impacto en el estado del servidor siguen estando permitidas incluso aunque la API se haya configurado como solo lectura por medio de la palabra clave api-readonly. Esta falta de comprobación permite que un atacante con credenciales API válidas vacíe la caché, desencadene una trasferencia de zona o envíe un NOTIFY.
