Description

ISC BIND 9 through 9.5.0a5 uses a weak random number generator during generation of DNS query ids when answering resolver questions or sending NOTIFY messages to slave name servers, which makes it easier for remote attackers to guess the next query id and perform DNS cache poisoning.

With Rapid7 live dashboards, I have a clear view of all the assets on my network, which ones can be exploited, and what I need to do in order to reduce the risk in my environment in real-time. No other tool gives us that kind of value and insight.
