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.

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.

Winamp 5.58 Exploit Development
The guys at the Exploit Database posted an awesome writeup on a Winamp 5.58 Exploit Development storming session – with some really cool results. In the end, they ended up writing a short assembly sequence to walk through the payload and replace bad characters with original shellcode bytes. Read more – Winamp 5.58 from Dos to Code Execution

It’s not often we wake up and find a massive 0day submitted to the Exploit Database – but today was different. Abysssec security released an Adobe Shockwave player 0day. We verified the exploit as part as our verification process in the Exploit database and made a short movie to demonstrate the the vulnerability.

Evocam Remote Buffer Overflow on OSX
This guide comes from my own journey from finding a buffer overflow in an OS X application to producing a working exploit. I have reasonably good exploit development skills having completed the Penetration Testing with BackTrack and Cracking the Perimeter training courses, and working on several buffer overflow exploits. The majority of my exploit development skills are based around Windows vulnerabilities and using the OllyDBG debugger.
