pyLoad js2py Python Execution
Posted on 22 February 2023
pyLoad versions prior to 0.5.0b3.dev31 are vulnerable to Python code injection due to the pyimport functionality exposed through the js2py library. An unauthenticated attacker can issue a crafted POST request to the flash/addcrypted2 endpoint to leverage this for code execution. pyLoad by default runs two services, the primary of which is on port 8000 and can not be used by external hosts. A secondary Click N Load service runs on port 9666 and can be used remotely without authentication.
