Hi, Not sure if anyone has seen yet, but there is a 2nd exploit being circulated. I just picked it up on metasploits SVN trunk.... The first was called "baliwicked_host", and the description was : 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 hostname queries to the target DNS server coupled with spoofed replies to those queries from the authoritative nameservers for that domain. Eventually, a guessed ID will match, the spoofed packet will get accepted, and due to the additional hostname entry being within bailiwick constraints of the original request the malicious host entry will get cached. The new one is called "baliwicked_domain" and its described as : This exploit attacks a fairly ubiquitous flaw in DNS implementations which Dan Kaminsky found and disclosed ~Jul 2008. This exploit replaces the target domains nameserver entries in a vulnerable DNS cache server. This attack works by sending random hostname queries to the target DNS server coupled with spoofed replies to those queries from the authoritative nameservers for that domain. Eventually, a guessed ID will match, the spoofed packet will get accepted, and the nameserver entries for the target domain will be replaced by the server specified in the NEWDNS option of this exploit.
