Title: | DNS Cache Snooping |
Summary: | NOSUMMARY |
Description: | Description: The remote DNS server answers to queries for third party domains which do not have the recursion bit set. This may allow a remote attacker to determine which domains have recently been resolved via this name server, and therefore which hosts have been recently visited. For instance, if an attacker 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... For a much more detailed discussion of the potential risks of allowing DNS cache information to be queried anonymously, please see: http://community.sidestep.pt/~ luis/DNS-Cache-Snooping/DNS_Cache_Snooping_1.1.pdf Risk factor : Low |
