This repository contains an exploit for CVE-2023-32031, a remote code execution vulnerability in Microsoft Exchange's PowerShell backend. The repository consists of a README.md describing the vulnerability and a payload.txt file containing a serialized PowerShell command payload. The payload is designed to be deserialized and executed on a vulnerable Exchange server, demonstrating the ability to run arbitrary PowerShell commands remotely. In this example, the payload attempts to execute 'Get-Mailbox' and launch 'mspaint.exe' on the target, proving code execution. The exploit targets Microsoft Exchange servers with the vulnerable PowerShell backend exposed. No explicit network endpoints or URLs are hardcoded in the payload, but exploitation requires network access to the Exchange server's PowerShell interface. The structure is simple, with the main exploit logic contained in the payload.txt file.
