Excellent location Using this methodology, we have uncovered several customers that may have been impacted by CVE-2021-44228 in a manner unrelated to the Infoblox product line. This specific attack vector has dependencies that make successful attacks difficult, and there have been additional mitigations put into place., The presence of this vulnerability does not increase the risk profile of the system. Hotfixes are now available toaddress both issues CVE-2020-8616 and CVE-2020-8617. The DNS resolver in unspecified versions of Infoblox DNS One, when resolving recursive DNS queries for arbitrary hosts, allows remote attackers to conduct DNS cache poisoning via a birthday attack that uses a large number of open queries for the same resource record (RR) combined with spoofed responses, which increases the possibility of successfully spoofing a response in a way that is more efficient than brute force methods.
