New DNS Vulnerability “TuDoor” Threatens Internet Security

A new critical vulnerability in the Domain Name System (DNS) has been found. This vulnerability allows a specialized attack called “TuDoor” that can poison DNS caches, cause denial-of-service (DoS) attacks, and deplete resources, posing a significant threat to internet security.

Specialists have conducted experiments that confirm the feasibility of the TuDoor attack, revealing its serious implications in real-world scenarios. A striking total of 24 widely used DNS programs, including BIND, PowerDNS, and Microsoft DNS, have been found vulnerable to TuDoor. In less than a single second, attackers can execute cache poisoning or DoS attacks against these vulnerable resolvers using just a handful of precisely fabricated packets.

SSL.com’s domain validation system’s bug found: Hacker exploited

Researchers tested 16 Wi-Fi router models, 6 operating systems, 42 DNS services, and about 1.8 million open DNS resolvers. The study found that TuDoor could exploit 7 routers, 18 DNS services, and 424,652 open DNS resolvers.

The researchers followed best practices for responsible disclosure by informing all affected vendors of the vulnerabilities. 18 vendors, such as BIND, Chrome, Cloudflare, and Microsoft, confirmed the findings and discussed ways to fix the issues. 33 CVE identifiers were assigned to the vulnerabilities, and an online tool for their detection was suggested.

Collaboration among researchers, developers, and users is crucial to ensure a secure digital environment. We need constant vigilance to address new vulnerabilities like TuDoor. By working together, we can achieve innovation and protection simultaneously.
