CVE-2023-28451 (GCVE-0-2023-28451)
Vulnerability from cvelistv5 – Published: 2024-09-18 00:00 – Updated: 2024-09-18 18:29
VLAI
Summary
An issue was discovered in Technitium 11.0.2. There is a vulnerability (called BadDNS) in DNS resolving software, which triggers a resolver to ignore valid responses, thus causing DoS (denial of service) for normal resolution. The effects of an exploit would be widespread and highly impactful, because the attacker could just forge a response targeting the source port of a vulnerable resolver without the need to guess the correct TXID.

CVE-2022-30257 (GCVE-0-2022-30257)
Vulnerability from cvelistv5 – Published: 2022-11-21 00:00 – Updated: 2025-04-30 15:02
VLAI
Summary
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.
Severity
