Critical Cisco VPN Flaw

Cisco published this week an advisory for the critical vulnerability CVE-2016-1287 in its ASA line of firewalls that have IKEv1/2 VPNs configured.  An exploit for the vulnerability would allow an unauthenticated, remote attacker to execute code on the device. A technical breakdown of the vulnerability can be found in the blog post at Exodus Intelligence who reported the vulnerability to Cisco. Exodus Intelligence is a 0-day research company, so this showcases some of their capabilities, while at the same time raises the question as to why they would publish the vulnerability rather than add it to their portfolio.

Newest Java Addresses Binary Planting Vulnerability

Oracle published a new version of Java 8, 7 and 6 to address a vulnerability in the installer. CVE-2016-0603 addresses a flaw where the attacker would seed the system with malicious DLLs that the installer would use instead of the DLLs included in the package itself. This type of vulnerability is generally known as binary planting.

As Oracle points out existing installations are not at risk. New installations should use the latest fixed packages to address the case where an end user might have visited a malicious site which could have prepared the machine for the attack by downloading altered versions of one of the DLLs involved. Fixed versions of Java are 6 update 113, 7 update 97 and 8 update 73.

Hunting For Vulnerable Functions In Microsoft Silverlight MS16-006

This week Microsoft released a patch for a critical Silverlight issue, MS16-006, and since I worked on Silverlight signatures in the past it caught my eye. It’s a Remote Code Execution vulnerability which allows attackers to run code of his or her choice on the victim machine. I had a hunch that something more was hiding. I started to analyze it as soon as I finished writing signatures for the existing patch. When I was working on the analysis Kaspersky Lab published a great blog post about the story of this vulnerability.

In this blog, I’m presenting analysis of a different function that was also fixed in the same patch.

Update: Patch Tuesday January 2016

Update: Kaspersky who is credited with finding MS16-006,the critical Silverlight vulnerability just published their story on how the bug was found. Very interesting, has to do with the Hacking Team breach and coding "standards" – take a look at their blog post for more info. They also made clear that this vulnerability is under attack in the wild and that we are looking at a true 0-day here. This changes our priorities – we now put MS16-006 at the top of our list. Take a look at your installations, see if you have Silverlight installed and address the flaw as soon as possible.

Original: The first Patch Tuesday of 2016 turns out to be low in numbers, but broad and packing quite a punch: six of the nine bulletins are rated critical, including the Windows Kernel and Office bulletins. In addition some rather important products are going End-of-Life and get their last patch update today. Microsoft is retiring support for all older browsers on each platform and will from here on only maintain the newest browser on each version of the OS.
