# CVE-2020-3452 PoC — Cisco ASA/FTD Path Traversal

This is a modified proof-of-concept exploit script for [CVE-2020-3452](https://nvd.nist.gov/vuln/detail/CVE-2020-3452), a directory traversal vulnerability affecting Cisco ASA and FTD devices.

The vulnerability allows unauthenticated, remote attackers to **read arbitrary files** on affected systems via a crafted HTTP request. This script automates that process by attempting to retrieve a predefined list of common configuration, portal, and HTML files, and stores successful responses locally.

> **⚠️ For authorized testing and research only. Use responsibly.**

## ✅ Features

- 🔁 Iterates through a curated list of target file paths known to exist on ASA/FTD systems.
- ✅ Only writes responses with **HTTP 200** and **non-empty content**.
- 🧮 Stops automatically after **200 successful downloads** to prevent abuse or noise.
- 🗂️ Writes all files to an `output/` directory, creating it automatically.
- 🔒 Sanitizes all output filenames to prevent accidental traversal or injection.
- 🧼 Suppresses SSL warnings (ASA certs are often self-signed).
