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.
