DNSpooq Flaws Allow DNS Hijacking of Millions of Devices

Seven flaws in open-source software Dnsmasq could allow DNS cache poisoning attacks and remote code execution. Researchers have uncovered a set of flaws in dnsmasq, popular open-source software used for caching Domain Name System (DNS) responses for home and commercial routers and servers. The set of seven flaws are comprised of buffer overflow issues and flaws allowing for DNS cache-poisoning attacks (also known as DNS spoofing). If exploited, these flaws could be chained together to allow remote code execution, denial of service and other attacks. Researchers have labeled the set of vulnerabilities “DNSpooq,” a combination of DNS spoofing, the concept of “a spook spying on internet traffic,” and the “q” at the end of dnsmasq.

DNSpooq Flaws Expose Millions of Devices to DNS Cache Poisoning, Other Attacks

By Eduard Kovacs on January 20, 2021 Researchers at Israel-based boutique cybersecurity consultancy JSOF this week disclosed the details of seven potentially serious DNS-related vulnerabilities that could expose millions of devices to various types of attacks. The vulnerabilities, collectively tracked as DNSpooq, impact Dnsmasq, a widely used piece of open source software designed to provide DNS, DHCP, router advertisement and network boot capabilities for small networks. Its DNS subsystem “provides a local DNS server for the network, with forwarding of all query types to upstream recursive DNS servers and caching of common record types.” The software is mainly written and maintained by Simon Kelley, who has informed users about the availability of patches. The vulnerability disclosure process began in August 2020 and several impacted vendors told customers that they are working on address the issues.
