Loading vulnerability…
CVE-2018-1000802 is a command injection vulnerability (CWE-77) in Python (CPython) 2.7’s shutil module, specifically the make_archive() function. The issue arises when unfiltered user-controlled input is passed into make_archive(), leading to improper neutralization of special elements used in a command. The vulnerability is reported as fixed after commit add531a1e55b0a739b0f42582f1c9747e5649ace.

This repository provides a proof-of-concept (PoC) exploit for CVE-2018-1000802, a vulnerability in Python's shutil.make_archive function on Windows systems. The exploit demonstrates how, under specific conditions (Python 2.7, Windows, zip utility available, and zipfile import failure), an attacker can inject arbitrary arguments into the zip command executed by make_archive. The provided 'poc.py' script contains three functions: one leaks arbitrary files (e.g., the Windows hosts file), one attempts to compress the entire C: drive (denial of service), and one hangs the process by passing malformed arguments. The repository includes a simulated 'zipfile.py' to force the import failure condition. The main exploit vector is local, requiring the attacker to execute Python code on the target system. The endpoints targeted are specific file paths on Windows. The repository is structured with a README, the PoC script, a test directory, and files to simulate the vulnerable environment.
