Critical
MetricsAV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H
Name of the Vulnerable Software and Affected Versions Technitium DNS Server versions 8.0.2 and earlier
Description An issue was discovered that allows variant V2 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.
Recommendations For Technitium DNS Server versions 8.0.2 and earlier, update to a version later than 8.0.2 to resolve the issue. At the moment, there is no information about a newer version that contains a fix for this vulnerability.
