Vulnerability Assessment Details

The remote BIND has dynamic updates enabled

Vulnerability Assessment Summary
Acertains if the UPDATE operation is implemented on the remote host

Detailed Explanation for this Vulnerability Assessment

The remote nameserver has dynamic updates enabled.

The dynamic updates let the bind administrator update the name
service information dynamically.

However, it is possible to trick bind to change the resource
record for the zone is it serves. A possible hacker may use this
flaw to hijack the traffic going the your servers and redirect
it to somewhere else.


Solution : If you use bind, add the option
permit-update {none
}


in your named.conf to disable this feature entirely.
