GuestStealer Wrapup

Posted in Cloud Computing, GuestStealer, Penetration Testing, ShmooCon, Virtualization Security, VMware, Vulnerability Assessment on March 1, 2010 by Tony Flick

In addition to the previously mentioned Nmap script, GuestStealer has now made its way into a Nessus plugin and a Metasploit module. Nessus Plugin 44646 was released by Tenable a few weeks ago and the Metasploit module was pushed up to the trunk last week.

GuestStealer has been mentioned in several articles and blog posts recently, including DarkReading – Tech Insight: Securing The Virtualized Server Environment and The Hacker News Network. While most have been accurate, several early blogs stated that GuestStealer used a cross site scripting attack to steal the guests. So to clarify and avoid any confusion, GuestStealer exploits the directory traversal vulnerability described in CVE-2009-3733.
