BIND TKEY Query Denial of Service

Disclosed

Description

This module sends a malformed TKEY query, which exploits an error in handling TKEY queries on affected BIND9 'named' DNS servers. As a result, a vulnerable named server will exit with a REQUIRE assertion failure. This condition can be exploited in versions of BIND between BIND 9.1.0 through 9.8.x, 9.9.0 through 9.9.7-P1 and 9.10.0 through 9.10.2-P2.

Time is precious, so I don’t want to do something manually that I can automate. Leveraging the Metasploit Framework when automating any task keeps us from having to re-create the wheel as we can use the existing libraries and focus our efforts where it matters.
