“Lorem Ipsum is simply dummy text of the printing and typesetting industry. Lorem Ipsum has been the industry’s standard dummy text ever since the 1500s, when an unknown printer took a galley of type and scrambled it to make a type specimen book. It has survived not only five centuries, but also the leap into electronic typesetting, remaining essentially unchanged. It was popularised in the 1960s with the release of Letraset sheets containing Lorem Ipsum passages, and more recently with desktop publishing software like Aldus PageMaker including versions of Lorem Ipsum.”

  1. Enum with Dirb and Nikto, also dirb -X .php for php-extensions .. http://ai.htb/uploads/ .. /db.php: This might be interesting… has been seen in web logs from an unknown scanner. .. /intelligence.php

  2. Looking at site we find a uploader on http://ai.htb/ai.php, this is promising towards initial foothold. /intelligence.php hints us on how to use it, install festival and use it’s text2wave to send input to the AI. Let’s try a test string “Say hi python” to see if the AI understands the input and gives us correct query result.

    root@p3:/opt/htb/machines/ai# echo “Say Hi Python” text2wave -o Hi-Python.wav

    Upload the file, Process It and this is the result: Our Understanding of your input is : say hi python Query result : print(“hi”)

So far so good. Lets see if we can enumerate using TTS.
