XShell

Lightweight shell emulation to exploit XXE

Goal

The goal of this tool is to ease the pentester's work by letting him concentrate only the important things: files to leak!

Usage

The script can be used as is or you can pass it a .ini file which will set some internal variables. To launch your first attack, you only need to set two variables:

• leak_url which is the URL on which the attack will be carried out
• payload which must be a valid Python dictionary (or a path to a file containing one) that contains all needed parameters that will be sent in the request (POST or GET)

TODO

• use JSON instead of Python dict (I'm too lazy for now)
• add base payloads (for OOB exploitation, or examples with some wrappers, get some inspiration from XXE Ceaht Sheet and XXEinjector)
• add cookie usage
• add GET option

Known problems

• problems with ~ path
• problems with path/file autocomplete
• problems with differentiation between files and directories
• all lines leaked by ls command are added to the autocomplete list (means the list can have a HUGE memory footprint)
