Microsoft Exchange ProxyShell RCE
Description
This module exploits a vulnerability on Microsoft Exchange Server that allows an attacker to bypass the authentication (CVE-2021-31207), impersonate an arbitrary user (CVE-2021-34523) and write an arbitrary file (CVE-2021-34473) to achieve the RCE (Remote Code Execution). By taking advantage of this vulnerability, you can execute arbitrary commands on the remote Microsoft Exchange Server. This vulnerability affects Exchange 2013 CU23 < 15.0.1497.15, Exchange 2016 CU19 < 15.1.2176.12, Exchange 2016 CU20 < 15.1.2242.5, Exchange 2019 CU8 < 15.2.792.13, Exchange 2019 CU9 < 15.2.858.9. All components are vulnerable by default.

- Collect and share all the information you need to conduct a successful and efficient penetration test
- Simulate complex attacks against your systems and users
- Test your defenses to make sure they’re ready
- Automate Every Step of Your Penetration Test
Time is precious, so I don’t want to do something manually that I can automate. Leveraging the Metasploit Framework when automating any task keeps us from having to re-create the wheel as we can use the existing libraries and focus our efforts where it matters.
