Fun with AIX Shellcode and Metasploit
In one of our recent pentests, we discovered an 0day for a custom C application server running on the AIX Operating System. After debugging the crash, we discovered that the bug could lead to remote code execution and since we don’t deal very often with AIX exploitation, we decided to write an exploit for it. The first steps were accomplished pretty quickly and we successfully diverted the execution flow by jumping to a controlled buffer. At this point, we thought we could easily generate some shellcode from MSF and enjoy our remote shell.

CA ARCserve – CVE-2012-2971
On a recent penetration test, we encountered an installation of CA ARCserve Backup on one of the target systems that piqued our interest. Like most “good” enterprise applications, ARCserve has processes that are running as SYSTEM so naturally, we went straight to work looking for vulnerabilities.

Onity Door Unlocker, Round Two.
On one of our engagements, we figured an Onity Hotel door unlocker would be useful to us. Inspired by the “James Bond” type setup we saw on the Spiderlabs blog post, we thought we’de try to build a small, simple and “TSA friendly” version of the Onity key unlocker.

Stand-Alone EM4x RFID Harvester
Continuing off from our last RFID Cloning with Proxmark3 post, we wanted to build a small, portable, stand-alone EM4x RFID tag stealer. We needed an easy way of storing multiple tag IDs whilst “rubbing elbows” with company personnel. The proxmark3 seemed liked an overkill and not particularly fast at reading em4x tags so we figured we’d try hooking up our RoboticsConnection RFID reader to a Teensy and see if we could make them play nicely together.

RFID Cloning with Proxmark 3
Our Proxmark 3 (and antennae) finally arrived, and we thought we’d take it for a spin. It’s a great little device for physical pentests, allowing us to capture, replay and clone certain RFID tags.

FreePBX Exploit Phone Home
During a routine scan of new vulnerability reports for the Exploit Database, we came across a single post in full disclosure by Martin Tschirsich, about a Remote Code Execution vulnerability in FreePBX. This vulnerability sounded intriguing, and as usual, required verification in the EDB. At first glance, the vulnerability didn’t jump out at us, especially as we are not familiar with the inner workings of asterisk. After a couple of emails back and forth with Martin, the path to code execution became clearer:

MS11-080 Exploit – A Voyage into Ring Zero
Every patch Tuesday, we, like many in the security industry, love to analyze the released patches and see if any of them can lead to the development of a working exploit. Recently, the MS11-080 advisory caught our attention as it afforded us the opportunity to play in the kernel and try to get a working privilege escalation exploit out of it.
