Recently Patched Java Vulnerability Exploited In the Wild: How (Not) Surprising

BeyondTrust Research Team, April 23rd, 2013

A type confusion vulnerability, recently patched in Java 7u21 and Java 6u45, has been spotted in the wild. According to a recent blog post from F-Secure, exploitation of CVE-2013-2423 started shortly after April 21st, 2013 and continues.

Given what we know about Java, none of this is surprising. “Why?!” you may ask, “didn’t we all just install the latest version of Java?” Nope. According to a survey conducted by Websense in March of this year, approximately 93.77% of browsers were vulnerable to the latest Java vulnerability, at the time of the study. With such a tremendous lag-time between Oracle releasing Java updates (which might fail to install in a least privilege environment), and Java installations being updated, it is no wonder that malware authors and other scum and villainy continue to take advantage of users and organizations that are running behind, if only by a few days. Sadly, most are behind by a few Java releases, leaving them exposed to much more than merely CVE-2013-2423.

Thankfully, there are a few options out there that can help lessen the likelihood of getting 0wned by some Java exploit. Our completely free Retina CS Community provides Java patching capability right out of the box. This allows you to immediately identify which resources on your network have Java, and gives you the ability to patch those assets. No more wandering around the office, asking people if it’s okay if you can update their Java installation. No more wondering if some publicly facing asset has a vulnerable version of Java on it. Control the controllable — ensure that your business is running up-to-date software, and avoid the headache that is becoming part of a botnet, or worse — having sensitive information stolen from your organization by Chinese hackers.
