Python RCE Deserialization AI / ML Fickling

Description

Fickling is a Python pickling decompiler and static analyzer. Prior to version 0.1.7, both ctypes and pydoc modules aren't explicitly blocked. Even other existing pickle scanning tools (like picklescan) do not block pydoc.locate. Chaining these two together can achieve RCE while the scanner still reports the file as LIKELY_SAFE. This issue has been patched in version 0.1.7.

Analysis

Fickling before version 0.1.7 allows local attackers to achieve arbitrary code execution through Python pickle deserialization by chaining unblocked ctypes and pydoc modules, bypassing the tool's safety scanner which incorrectly reports malicious files as LIKELY_SAFE. An attacker with user interaction can exploit this vulnerability to execute code with the privileges of the Python process. …
