ManageEngine Desktop Central 9 FileUploadServlet ConnectionId Vulnerability
Description
This module exploits a vulnerability found in ManageEngine Desktop Central 9. When uploading a 7z file, the FileUploadServlet class does not check the user-controlled ConnectionId parameter in the FileUploadServlet class. This allows a remote attacker to inject a null bye at the end of the value to create a malicious file with an arbitrary file type, and then place it under a directory that allows server-side scripts to run, which results in remote code execution under the context of SYSTEM. Please note that by default, some ManageEngine Desktop Central versions run on port 8020, but older ones run on port 8040. Also, using this exploit will leave debugging information produced by FileUploadServlet in file rdslog0.txt. This exploit was successfully tested on version 9, build 90109 and build 91084.

- Collect and share all the information you need to conduct a successful and efficient penetration test
- Simulate complex attacks against your systems and users
- Test your defenses to make sure they’re ready
- Automate Every Step of Your Penetration Test
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.
