Should Michael Lynn have told at Black Hat or not?

Among the latest developments in the Michael Lynn story at the Black Hat conference is that the research analyst was served with a temporary restraining order  barring him from discussing the flaw that could compromise Cisco's unpatched routers . The order was filed by Cisco and Internet Security Systems, Lynn's former employer, from which he either resigned or was forced to resign after giving a presentation on how a malicious hacker could exploit a flaw in unpatched Cisco router software that  "could crash those systems or intercept Internet communications." According to Red Herring, Lynn explained his actions by saying,

"I feel I had to do what’s right for the country and the national infrastructure,” he said. “It has been confirmed that bad people are working on this \[compromising IOS\]. The right thing to do here is to make sure that everyone knows that it’s vulnerable.”

Cisco and ISS disagreed and said releasing the data was premature, says Network World. The two companies also filed a temporary restraining order against Black Hat to prevent the organization from distributing video of Lynn's presentation.
But Network World says their effort may be too late  and that some copies of the CD may be in circulation.
In a statement  on its Web site, Cisco said it "respects and encourages the work of independent research scientists; however, we follow an industry established disclosure process for communicating to our customers and partners."
The statement continued: "It is important to note that the information presented at the Black Hat Conference yesterday was not a disclosure of a new vulnerability or a flaw with Cisco IOS software. The research presented explores possible ways to expand exploitations of known security vulnerabilities impacting routers."
The company also urged its customers to "upgrade their software to the latest available versions."
Let's hope this issue is resolved quickly and in a reasonable way that fixes the flaw once and for all and gives Michael Lynn his due.

What People Are Saying

Ive known Mike for about 20

Ive known Mike for about 20 years now... and if the kid said he was doing th right thing... then he was doing the right thing!!!

Matters of national security cannot be driven by corporate greed

Abaddon absolutely did the right thing. Cisco's position that this is fixed is absolutely incorrect. What they have done is made sure that new systems are not vulnerable from the XML vector for any new equipment.

They have severely underplayed the potential for disaster here and made no active effort at all to strongly encourage their federal customers fix this immediately. Shame on them for letting it get this far. I am not sure what the basis of ISS's claim that they have a fix for this is based on. Are they going to put a Proventia box in front of the router? Shame on ISS for letting a vendor sweep this under. While Cisco has a big problem with its gear and IOS, ISS has a far bigger problem in that the trust level they have developed over the years is absolutely gone.

Matters of national security cannot be driven by corporate greed. It was bad enough when Enron destroyed the peoples ability to retire. Mike has made the single strongest case for open source and full disclosure. I too have known Mike for years and I am immensely proud of him. People are not harping on the real problem, that being that once virtual processes are an integral part of IOS this will be easy to script and worm.

Where's the patch?

I am puzzled that Cisco knew about the flaw but has done nothing to notify its customers or send them automaticaly a CD with the corrected version of their software as a protective measure. 

Marian, you imply that the

Marian, you imply that the vulnerability hasn't been fixed. If Cisco is to be believed, it was patched in April. The problem is that it's throught many routers remain unpatched.

Let's hope there's a silver lining to this cloudy tale: boosted awareness of the problem should cause more router owners to keep up to date with security patches.

Lynn's service to the public

I'm always fasinated when folks like Mike Lynn get toasted by the likes of Cicso, Microsoft or other large corporate conglomorates that sneeze and wake up law enforcement which in turn harass people like Lynn by perverting the use of law to silence those who do the computing public a service though the information disclosed about compromised operating systems.

These backdoors have been in place (deliberately) for many years now. Do you really think our's or any other government or covert group operating under the scope of public awareness will allow the public to freely communicate with each other in an age of elite deception capstoned by the ruling rich? Not likely, updated software, sure it's updated, with new and better hidden backdoors.

My hats off to Mike Lynn and others like him for his service to the general public well being, as we are deserved of our privecy no matter how desired others feel otherwise. Kudos to you, Mike Lynn.

I think Cisco and ISS should

I think Cisco and ISS should have allowed it and I think he was right to make it public. Takes some of the heat off Microsoft :) At least updates from Microsoft are free. Maybe Cisco is worried that this will bring too much attention to their sloppy code and some class action lawsuit will require that patches to fix security holes be free.
Cisco going after Lynn makes me question the $50K in switches I was just about to recommend to a customer. I'm not sure I can justify a price premium for their product anymore with how much they've blown this out of proportion.

Yes he should have, and it

Yes he should have, and it bothers me tremendously that, given such a large percentage of the internet relies on Cisco routers, that Cisco, in its greed and pride, is trying to squash Lynn in a vain attempt to make us believe that they have an inpenetrable system. I hope that Lynn will very much get his due!! My confidence in Cisco has just been greatly reduced!

Not only Yes, but Hell Yes.

Not only Yes, but Hell Yes. Damn Cisco and ISS for trying to cover this up.
