If a device crashes when being scanned - it's a vulnerability.
It sounds to me as if what happened was that he ended up driving the CPUs of the devices in question to 100%, and they stopped handling control-plane traffic and fell over. There are infrastructure self-protection best current practices (BCPs) which can be deployed to defend against infrastructure-targeted DoS. I've only seen this happen a few hundred times or so, so I could be wrong, of course. ;> As the original poster posited:
Is this a configuration error of the networking devices?
The answer is, almost assuredly, "Yes." ----------------------------------------------------------------------- Roland Dobbins <rdobbins () arbor net> // <http://www.arbornetworks.com> Injustice is relatively easy to bear; what stings is justice. -- H.L.
