A BIND 9.x implementation operating in a split DNS configuration must be approved by the organizations Authorizing Official.

Description

<VulnDiscussion>BIND 9.x has implemented an option to use "view" statements to allow for split DNS architecture to be configured on a single name server. If the split DNS architecture is improperly configured there is a risk that internal IP addresses and host names could leak into the external view of the DNS server. Allowing private IP space to leak into the public DNS system may provide a person with malicious intent the ability to footprint your network and identify potential attack targets residing on your private network.</VulnDiscussion><FalsePositives></FalsePositives><FalseNegatives></FalseNegatives><Documentable>false</Documentable><Mitigations></Mitigations><SeverityOverrideGuidance></SeverityOverrideGuidance><PotentialImpacts></PotentialImpacts><ThirdPartyTools></ThirdPartyTools><MitigationControl></MitigationControl><Responsibility></Responsibility><IAControls></IAControls>
