voting's Introduction

Blockchain Based Voting

It is python based implementation of blockchain technology to be used for e-Voting. By considering each vote as transaction to be added to pending_transaction, which is ready to be mined and included in a Block. And then the newly created block is added to the blockchain and broadcast to all the nodes.

Features

The blockchain :

Possibility of adding multiple nodes to the blockchain
Proof of Work (PoW)
Simple conflict resolution between nodes
Transactions with ecdsa signature verification

The blockchain client has the following features:

React based Web App
Here is Client README.md

The blockchain API server for miners

Block explorer
Transaction and Block verification & Broadcasting
Block mining
p2p communication

Installation

first clone the repository by typing this code into your terminal.

git clone https://github.com/ephremdeme/voting.git

simply cd voting and install all the dependencies from requirement.txt by typing this code

pip install -r requirements.txt

First export Flask api app using export FLASK_APP=api
on linux terminal run ./run.sh, this will apen a 6 tab terminal for 6 network nodes
or add each node like python BlockchainAPINode.py 5000
to add peer node to the blockchain, open postman POST request localhost:5000/register-node/broadcast and send json { "new_node": "http://localhost:5002"}
to start the blockchain client, go to cd client and execute: python clientGUI.py
finally open your browser and go to localhost:5000

Any suggestion or contribution is welcome.

Dashboard for miners

Implement a react dashboard component to be integrated to this system.
The component have to do this features:
-> Show miners "mine" button
-> Show miners "consensus" button, to interact with other peers and update the chain incase it is outdated
-> Show miners connect to other nodes option

all these components interact with flask API.
like localhost:5000/mine to mine new block,
localhost:5000/consensus to update the chain
localhost:5000//register-node/broadcast to register new nodes by giving its address

Hardcoded secret key

Hello,

We are a cybersecurity research group from the CISPA Helmholtz Center for Information Security and Ca’ Foscari University of Venice. We recently conducted an analysis of the session management used in your web application as part of our research. We have discovered a security vulnerability that we believe requires your attention.

Vulnerability Description:

After our analysis, we have identified that your application is using a hard-coded secret key that is leaked through GitHub. If operators who install your web application do not change this secret key, they are vulnerable to cookie forgeries. The cookie forgery attack allows an attacker, knowing the key used to sign a cookie, to forge new arbitrary cookies to impersonate and take over other accounts.

link to the relevant code part

Recommendation for Mitigation:

To address this vulnerability and enhance the security posture of your web application, we highly recommend setting the secret key from an environment variable. If the environment file is not shared on GitHub then this would force operators of your application to create their own key upon installation, forcing them to set their own secure secret key.

We hope this notification helps improve your security. Can you take a look into the relevant code parts and comment on the issue?
