00:00 - Introduction
01:00 - Start of nmap
02:00 - Checking out the web page and finding command injection in the URL
03:20 - Space appears to be a bad character with command injection. Normal tricks like brace expansion or IFS don't work.
07:20 - Trying IFS to be a space but the trailing character makes it difficult
12:00 - Taking a step back from the RCE, downloading the PDF to examine metadata and discovering it was made with pdfkit 0.8.6, which has public POC's against it
13:00 - The POC puts a space before the exploit which then removes the space being a bad character in our exploit
14:29 - Beyond Root/Edit: Using $- to terminate the $IFS, allowing us to bypass the need to prepend the space
20:30 - End of edit, shell as ruby, discovering credentials in a config file for henry
22:53 - Henry can run sudo, discover he can execute a ruby script
25:50 - Looking up a ruby deserialization exploit with YAML
27:35 - Finding a different payload and getting a root shell
