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. Se descubrió un problema en Technitium DNS Server hasta 8.0.2 que permite la variante V1 de resolución de nombres de dominio no deseada. Un nombre de dominio revocado aún se puede resolver durante mucho tiempo, incluidos dominios caducados y dominios maliciosos eliminados. • https://github.com/TechnitiumSoftware/DnsServer/blob/master/CHANGELOG.md#version-81 • CWE-706: Use of Incorrectly-Resolved Name or Reference •
