TrustKeeper Scan Engine Update - February 6, 2013

The latest update to the TrustKeeper Scan Engine is now available. It includes coverage for over 30 vulnerabilities for products such as Apache, Cisco IOS, Oracle Database and MySQL Servers, PHP, Samba and Ruby on Rails.

Of the vulnerabilities in the update, the most popular (at least according to twitter), are the recent XML and JSON parsing vulnerabilities in Ruby on Rails (CVE-2013-0156 and CVE-2013-0333). These vulnerabilities could allow an unauthenticated attacker remote code execution on a vulnerable web application. If you are using the Ruby on Rails, we highly recommending that you upgrade to the latest stable release.

If you're interested in reading more about these Ruby on Rails vulnerabilities and our perspective, we recommend checking out Ryan Barnett's recent posts (here and here), which provide ModSecurity mitigations for Ruby on Rails and some information about what types of scanning for these vulnerabilities we've seen in the wild.

As always, this update also includes improvements to existing tests and better evidence reporting.
