It's the week of December 17th and that can only mean one thing: a week until Christmas! For those of you who don't celebrate Christmas, a very happy Hanukkah/Chanukah, Kwanzaa, Diwali, Chinese New Year, Winter Solstice and Las Posadas to you all!

This is our last weekly wrap-up this year, but as always, we'll be publishing an annual Metasploit wrap-up just after the new year that covers all the shells we got in 2020.

Without further ado, let's jump into it!

CVE-2020-1054: I heard you still got Windows 7, so let’s play a game

Oh dear Windows 7, you just can't catch a break. timwr continued his LPE contributions this week with a exploit for CVE-2020-1054, a OOB write vulnerability via the DrawIconEx() function in win32k.sys. This bug was originally found by bee13oy of Qihoo 360 Vulcan Team and Netanel Ben-Simon and Yoav Alon of Check Point Research and was reported to Microsoft in May 2020. The module targets Windows 7 SP1 x64 and grants SYSTEM level code execution. Whilst Windows 7 is EOL, it is still being used by 17.68% of all Windows computers as of November 2020 according to some statistics. That is still a fair market share even if its popularity has been gradually diminishing over time. Furthermore, although users can update Windows 7, it is now mostly a manual process unless you are on one of Windows extended support plans. This increases the time needed to apply patches and also increases the possibility that users may forget to install specific patches. Hopefully none of your clients’ systems are still running Windows 7, but in case you are on a pen test and happen to encounter one, this exploit might provide the access you need to pivot further into the network.

Parse me to your shell

The second highlight of this week was a PR from our very own wvu-r7 targeting CVE-2020-14871, a buffer overflow within the parse_user_name() function of the PAM (Pluggable Authentication Module) component of Solaris SunSSH running on Oracle Solaris versions 10 and 11. The exploit supports SunSSH 1.1.5 running on solaris 10u11 1/13 (x86) within either VMWare or VirtualBox and grants unauthenticated users a shell as the root user. Pretty nifty stuff!
