Burpsuite Core Generator for Python Penetration Testing Primer

Recently, I received a network security book "Python Black Hat" presented by the Electronic Industry Press, with a total of 24 experiments in the book, and today reproduces the 15th experiment (BurpSuite Core Generator Plugin), my test environment is MBP computer + Kali virtual machine + DVWA online range. At present, only python2.7 is supported, and the soft link is adjusted slightly, and then I uninstalled the JDK and Burpsuite on Kali, and finally used JDK 1.8 and Burpsuite 1.7.36, and successfully reproduced this experiment, by the way, after doing many experiments, I am familiar with it~

Step 1: Prepare the environment

times 安装jdk1.8

apt-get update
apt-get install software-properties-common
apt-add-repository 'deb http://security.debian.org/debian-security stretch/updates main'
apt-get update
apt-get install openjdk-8-jdk           

Select JDK1.8

update-alternatives --config java           

Update soft connection for python2

ln -s /usr/bin/python2 /usr/bin/python           

Install an earlier version of Burpsuite 1.7.36

wget https://portswigger.net/burp/releases/download?product=community&version=1.7.36&type=linux
sudo chmod +x burpsuite_community_linux_v1_7_36.sh
sudo ./burpsuite_community_linux_v1_7_36.sh           

The import is successful, here you need to pay attention to the path does not have Chinese

Step 2: Prepare the experimental site

Choosing a DVWA Online Range[1]

Step 3: Actual combat drill

1. Enter the xss injection module and submit a string

2. Then in the proxy module of burp, send the carrier core to the intruder module

3、在intruder模块中payload页面下，选择payload type为Extension-generated，然后在payload options里面选择BHP Payload Generator 就大功告成了～

4. Click Start Attack, the pop-up window is actually tested here, but the display is not friendly
