Pwn2Own Day 1: Hackers Earn $280k For Hacking Chrome, Flash, Safari (securityweek.com)

Posted by timothy on from the an-honest-living dept.

wiredmikey writes: Pwn2Own 2016 contestants hacked Apple's Safari Web Browser, Adobe Flash Player and Google Chrome, and earned more than $280,000 on the first day of the competition taking place this week alongside the CanSecWest conference in Vancouver, Canada. This is the first edition of Pwn2Own where contestants have been invited to escape a VMware virtual machine for a bonus of $75,000, though there has not been a successful exploit yet in this class by any contestant this week. It remains to be seen if contestants manage to surpass last year's total payout, when white hat hackers earned $552,000 at Pwn2Own.

    I keep waiting for someone to find a vulnerability in VMware that lets a VM keep running without appearing in inventory. Bonus points if it can vMotion itself and have access to the management side to manipulate networks.

      It's not a vulnerability, but you can hide it completely from displayed inventory (vCenter) by taking away access from vpxuser. Or from root on a standalone ESXi instance.

      I can see a VM playing games with hitting the vCPU hard so DRS rules kick off and bounce the VM around to different physical ESXi boxes, and then using timing techniques, check to see which ESXi box it is sitting on, in order to move to a particular node in a vSphere cluster.

      If a VM can get access to the management interface [1], that would be a game over. From there, it would be a matter of brute forcing users (although 6.0 will lock the account for 120 seconds after ten bad guesses) to get access to critical stuff.

      Two different points. If one has a clue, it isn't hard to ensure that a VM doesn't have access to the management network. However, if there is a weakness in the hypervisor, a rogue/compromised VM getting access to that isn't a good thing.

      However, being able to use DRS so a VM physically runs on a box (perhaps to use a hardware security hole with the physical CPU like RAM row hammering) is one attack vector that can come into play. It is relatively minor, but it is present.

      Because browsers have a very large, very public attack surface and come from the desktop mentality where security wasn't even considered until recently...

      Databases etc *should* have limited exposure to untrusted networks, and thus less attack surface - you typically interact with a frontend application rather than directly with the database for instance.

      Webservers are obviously inherently public, but security on web servers has been a serious concern for a long time plus the typical web server is far less complex than a browser. Most web based vulnerabilities these days exist in individual applications rather than the web server software itself.

    Virtualization is one of the biggest defensive tools we have against compromise. From being able to roll back or discard/spin up a VM if it is compromised to popping snapshots of disk and memory and scanning those for running malware, or just to keep bad stuff from trying to flash firmware to a real device like a bare metal hard disk, virtualization is a must.

    My concern is that it isn't just the ESXi hypervisor that keeps the bad guys out. There are four main hypervisors out there that need to be looked at: ESXi, Hyper-V, Linux KVM, and Xen, with Xen giving way to KVM. There are also containers like LXC and Docker that are important as well. I can see KVM being more of an issue over time as OpenStack goes from "cool toy" to production quality.

    The good thing is that hypervisors in general have a limited attack surface, run relatively few applications, and tend to have a better focus on security than general operating systems.

    The most likely exploit on a Hypervisor is with a Paravirtualized driver.

      I used to crash VirtualBox trying to run an opengl on a Ubuntu guest. If I recall correctly it was crashing because VB didn't support some shared Opengl context thing. If it's running with graphics it shouldn't take long to exploit.
