The dangerous zero-day exploit in the Java Runtime Environment (CVE-2012-4681) was documented and proof of concept was added to Metasploit, which became public knowledge before a fix was made available.

    As a direct result, three billion devices running Java were vulnerable to remote code exploitation for roughly 48 hours. A second exploit hit in September and targeted Internet Explorer 9. Successful exploitation would allow remote compromise of the system with the installation of the Poison Ivy backdoor. Both zero-day exploits were used in advanced persistent attacks.
