RE: Publicly Disclosing A Vulnerability

["Josh Perrymon" <perrymonj () networkarmor com>]

Ok,

I have already worked with the Client and Vendor and the vendor is providing a free upgrade to the customer for no 
charge to correct the vulnerable issue. 
My focus is to protect the customer first...   The customer agreed that the vulnerability could be disclosed after they 
upgrade...

So I guess the only part of this I didn't care for was the vendor saying that they did not want me to release this 
information to the public.... I think it's because the client would get the upgrade for free instead of paying for it.

Ok,

I believe in working with the Vendor to inform then of vulnerable software upon finding it in the wild so on...
But I have a question...

While performing a pen-test for a large company I found a directory transversal vulnerability in a search program-
I used Achilles and inserted the DT attack in a hidden field and posted it to the web server. This returned the 
win.ini..
Cool..

Well... I called the company up and got the lead engineer on the phone.. He seemed a little pissed.
He told me that they found the hole internally a couple months ago but they don't want it public and they said I should 
not tell anyone about it because they don't want their customers at risk.

So I ask the list- what is more beneficial to the customer? Not publicly disclosing the risk and hoping that they 
follow the suggestions of the vendor to upgrade?  Or waiting 30 days and send it out?
