DNS Cache Snooping

Vulnerability Assessment Summary
DNS Cache Snooping

Detailed Explanation for this Vulnerability Assessment

Summary :

Remote DNS server is vulnerable to Cache Snooping attacks.

Description :

The remote DNS server answers to queries for third party domains which do
not have the recursion bit set.

This may permit a remote attacker to acertain which domains have recently
been resolved via this name server, and therefore which hosts have been
recently visited.

For instance, if a possible hacker was interested in whether your company utilizes
the online services of a particular financial institution, they would
be able to use this attack to build a statistical model regarding
company usage of aforementioned financial institution. Of course,
the attack can also be used to find B2B partners, web-surfing patterns,
external mail servers, and more...

DNS cache information to be queried anonymously, please see:
