VetorAV:N/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H
Name of the Vulnerable Software and Affected Versions PowerDNS Authoritative Server versions prior to 4.0.7 PowerDNS Authoritative Server versions prior to 4.1.7
Description A vulnerability was found in the HTTP Connector of the Remote backend, related to insufficient validation of user data when building an HTTP request from a DNS query. This allows a remote user to cause a denial of service by making the server connect to an invalid endpoint, or possibly information disclosure by making the server connect to an internal endpoint.
Recommendations For PowerDNS Authoritative Server versions prior to 4.0.7, update to version 4.0.7 or later. For PowerDNS Authoritative Server versions prior to 4.1.7, update to version 4.1.7 or later. As a temporary workaround, consider restricting access to the HTTP Connector in the Remote backend to minimize the risk of exploitation.
