InfoSec Handlers Diary Blog

The ISC has covered Java recently a number of times with Johannes's commentary and the January 2013 OUCH! heads-up by Adam of the issues with Java 7 update 10 and the current 0-day doing the rounds.

However, the guys over at Immunity have released their analysis (PDF) of the MBeanInstantiator.findClass 0-day. Other than the excellent review of the 0-day they comment that:

"This vulnerability affects JDK 6 (at least from update 10 and greater) up to the latest JDK 7 update 10. The comments in the source code state that these classes MBeanInstantiator and JmxMBeanServer are available since JDK 5, but we did not check versions before JDK 6 update 10. "

Let's hope Oracle patching this one soon, and if the article is correct, completely this time.
