CVE-2009-3555 Cisco update

Dan O'Connor Dan O'Connor Profile: Dan O'Connor

This is something I covered at the start of the year, I just noticed today that Cisco has updated the their advisory for the vulnerability with patch information and additional products.

This was the issue that could allow a malicious user to use the renegotiation in SSL / TLS to preform a MIM / Man In The Middle attack on secure sessions.

I created somewhat of an explanation from a variety of sources, you can read it here

It’s a pretty interesting attack, the RFC has excellent information about renegotiation and why the protocol has the ability to do it.  Also I think there is payload in Metaspoit to test it out, if there is not I know it’s out there if you look.
