Metasploit Bounty - the Good, the Bad and the Ugly

Corelan Team (Lincoln) July 27, 2011

On June 14, 2011 HD Moore announced the Metasploit Bounty contest, offering a cash incentive for specific vulnerabilities to be submitted as modules in the Metasploit Framework. Titled "30 exploits, $5000 in 5 weeks", a post on the Rapid7 blog lists the 30 "bounties" selected by the MSF team, waiting for someone to claim and submit a working exploit module. Read more

Universal DEP/ASLR bypass with msvcr71.dll and mona.py

corelanc0d3r July 3, 2011

Over the last few weeks, there has been some commotion about a universal DEP/ASLR bypass routine using ROP gadgets from msvcr71.dll (written by Immunity Inc) and the fact that it might have been copied into an exploit submitted to Metasploit as part of the Metasploit bounty.

Death of an ftp client / Birth of Metasploit modules

corelanc0d3r October 12, 2010

Over the past few weeks, Corelan Team has given its undivided attention to fuzzing ftp client applications. Using a custom built ftp client fuzzer, now part of the Metasploit framework, the team has audited several ftp clients and applications that use an embedded client ftp component. One example of such an application is a tool that would synchronize / backup data from a computer to a remote ftp server. The 3 main audit/attack vectors that were used during the "project" were send back overly long responses to ftp commands / requests sent by the ftp client to the server send back a file/directory listing that contains overly long file/folder names try to download a file that has an overly long filename.
