Our basic task is to write arbitrary code as a Python function, marshal the function, base64 encode it, and insert it into a generic pickle which will decode, unmarshal, and call the function. The attacker can use that to include references to one of the subprocess modules to run arbitrary commands on the host. and a hacker knowing some exploit in your code or system used the python function. What is Serialization/Deserialization? How can we exploit it?. Serialization is the process of converting an object to a byte stream, and the inverse of which is converting a byte stream back to on python object hierarchy. yaml or jsonpickle module is used for deserialization of serialized data. Since I struggled a bit to find reference material online on the subject, I decided to make a blog post documenting my discoveries, exploit code and solutions.
