FUSE is a penetration testing system designed to identify Unrestricted Executable File Upload (UEFU) vulnerabilities. The details of the testing strategy is in our paper, “FUSE: Finding File Upload Bugs via Penetration Testing”, which appeared in NDSS 2020. To see how to configure and execute FUSE, see the followings.

Setup

Install

FUSE currently works on Ubuntu 18.04 and Python 2.7.15.

• Install dependencies

#apt-get install rabbitmq-server
#apt-get install python-pip
#apt-get install git

• Clone and build FUSE

$ git clone https://github.com/WSP-LAB/FUSE
$ cd FUSE && pip install -r requirements.txt

If you plan to leverage headless browser verification using selenium, please install Chrome and Firefox web driver by refering selenium document.

Usage

Configuration

• FUSE uses a user-provided configuration file that specifies parameters for a target PHP application. The script must be filled out before testing a target Web application. You can check out README file and example configuration files.
• Configuration for File Monitor (Optional)

$ vim filemonitor.py
…
10 MONITOR_PATH=’/var/www/html/’ <- Web root of the target application
11 MONITOR_PORT=20174 <- Default port of File Monitor
12 EVENT_LIST_LIMITATION=8000 <- Maxium number of elements in EVENT_LIST
…

Execution

• FUSE

$ python framework.py [Path of configuration file]

File Monitor

$ python filemonitor.py

• Result
  • When FUSE completes the penetration testing, a [HOST] directory and a [HOST_report.txt] file are created.
  • A [HOST] folder stores files that have been attempted to upload.
  • A [HOST_report.txt] file contains test results and information related to files that trigger U(E)FU.
