MediumCVSS 6.9 EPSS 0.39%
-
HighCVSS 7.5 EPSS 0.54%
An issue was discovered in Technitium through 11.0.2. It enables attackers to launch amplification attacks (3 times more than other "golden model" software like BIND) and cause potential DoS.
-
HighCVSS 7.5 EPSS 0.53%
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 hig...

HighCVSS 7.5 EPSS 0.21%
An issue was discovered in Technitium through 11.0.3. It enables attackers to conduct a DNS cache poisoning attack and inject fake responses within 1 second, which is impactful.
-
HighCVSS 7.5 EPSS 0.53%
An issue was discovered in Technitium through 11.0.2. The forwarding mode enables attackers to create a query loop using Technitium resolvers, launching amplification attacks and causing potential DoS.
-
HighCVSS 7.5 EPSS 0.65%
Technitium 11.5.3 allows remote attackers to cause a denial of service (bandwidth amplification) because the DNSBomb manipulation causes accumulation of low-rate DNS queries such that there is a large-sized response in a burst of traffic.
-
HighCVSS 7.5 EPSS 1.7%
The DNS protocol in RFC 1035 and updates allows remote attackers to cause a denial of service (resource consumption) by arranging for DNS queries to be accumulated for seconds, such that responses are later sent in a pulsing burst (which can be considered traffic amplification in...

HighCVSS 7.5 EPSS 0.71%
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.
-
CriticalCVSS 9.8 EPSS 0.73%
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 b...

MediumCVSS 4.3 EPSS 0.54%
A vulnerability in the bailiwick checking function in Technitium DNS Server <= v7.0 exists that allows specific malicious users to inject NS records of any domain (even TLDs) into the cache and conduct a DNS cache poisoning attack.
