DNS AXFR

Vulnerability Assessment Summary
Acertains if the remote name server allows zone transfers

Detailed Explanation for this Vulnerability Assessment

The remote name server permits DNS zone transfers to be performed.
A zone transfer will permit the remote attacker to instantly populate
a list of potential targets. In addition, companies often use a naming
convention which can give hints as to a servers primary application
(for instance, proxy.company.com, payroll.company.com, b2b.company.com, etc.).

As such, this information is of great use to a possible hacker who may use it
to gain information about the topology of your network and spot new
targets.

Solution: Restrict DNS zone transfers to only the servers that absolutely
need it.

Network Security Threat Level: Medium
