| CVE | 摘要 | 来源 | 最高 CVSS | EPSS % | 公开时间 | 更新时间 |
|---|---|---|---|---|---|---|
| CVE-2022-48256 | Technitium DNS Server before 10.0 allows a self-CNAME denial-of-service attack in which a CNAME loop causes an answer to contain hundreds of records. | [email protected] | 7.5 | 0.41% | 2023-01-13 | 2025-04-07 |
| CVE-2022-30258 | An issue was discovered in Technitium DNS Server through 8.0.2 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.
