Description

This module abuses the JMX classes from a Java Applet to run arbitrary Java code outside of the sandbox as exploited in the wild in February of 2013. Additionally, this module bypasses default security settings introduced in Java 7 Update 10 to run unsigned applet without displaying any warning to the user.

Module Options

To display the available options, load the module within the Metasploit console and run the commands 'show options' or 'show advanced':

msf > use exploit/multi/browser/java_jre17_jmxbean_2
msf exploit(java_jre17_jmxbean_2) > show targets
    ...targets...
msf exploit(java_jre17_jmxbean_2) > set TARGET < target-id >
msf exploit(java_jre17_jmxbean_2) > show options
    ...show and set options...
msf exploit(java_jre17_jmxbean_2) > exploit

Time is precious, so I don’t want to do something manually that I can automate. Leveraging the Metasploit Framework when automating any task keeps us from having to re-create the wheel as we can use the existing libraries and focus our efforts where it matters.
