PROPOSAL: Cluster 23 NETCONF - (12 candidates)



The following candidates are associated with network configuration,
mostly dealing with filters of one sort or another.

Some of these candidates satisfy the CVE vulnerability definition
because they are useful for information gathering activities, even
though they "work as advertised."  Consider allowing traceroute or DNS
zone transfers.  Should those candidates be treated the same as
running finger?

Let's consider Gene Spafford's rule of thumb:

>Any software that functions according to its specification, and whose
>correct functioning is within the bounds of a common security policy
>(but not necessarily *every* policy) will NOT be considered a
>vulnerability for inclusion in the CVE."
>
>the finger program would not be a vulnerability so long as all
>of its functions are correct and known.   We might allow its use in
>an academic environment, so it is not a vulnerability.

Does this rule of thumb apply to the candidates in this NETCONF
cluster?

A different issue - how far do we go to separate the functions of
various devices on the network?  In the draft CVE, I've identified two
different types of devices: hosts, and network management devices
(e.g. routers, firewalls, IDSes) which deal with managing the traffic
between hosts.  The roles of routers/firewalls/IDSes/etc. are nearly
interchangeable, so I do not think it is appropriate to make separate
CVE entries for each one, in most cases.  I call this the "Two
Different Network Devices" content decision, which is a specialization
of "Different Functionality, Different Configuration Problem."
