A vulnerability was found in Technitium DNS Server up to 8.0.2. It has been classified as problematic. This affects some unknown functionality of the component Domain Name Resolution Handler. CWE is classifying the issue as CWE-706. The product uses a name or reference to access a resource, but the name/reference resolves to a resource that is outside of the intended control sphere. This is going to have an impact on confidentiality, integrity, and availability. The summary by CVE is:
An issue was discovered in Technitium DNS Server through 8.0.2 that allows variant V1 of unintended domain name resolution. A revoked domain name can still be resolvable for a long time, including expired domains and taken-down malicious domains. The effects of an exploit would be widespread and highly impactful, because the exploitation conforms to de facto DNS specifications and operational practices, and overcomes current mitigation patches for "Ghost" domain names.
