Versions of the JBoss Seam 2 framework < 2.2.1CR2 fails to properly sanitize inputs to some JBoss Expression Language expressions. As a result, attackers can gain remote code execution through the application server. This module leverages RCE to upload and execute a given payload. Versions of the JBoss application server (AS) admin-console are known to be vulnerable to this exploit, without requiring authentication. Tested against JBoss AS 5 and 6, running on Linux with JDKs 6 and 7. This module provides a more efficient method of exploitation - it does not loop to find desired Java classes and methods.

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/http/jboss_seam_upload_exec
msf exploit(jboss_seam_upload_exec) > show targets
...targets...
msf exploit(jboss_seam_upload_exec) > set TARGET < target-id >
msf exploit(jboss_seam_upload_exec) > show options
...show and set options...
msf exploit(jboss_seam_upload_exec) > 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.
