Web interface for remote reset of Active Directory passwords.

Written to address the mess of Microsoft licensing associated with remote users and password write-back, specifically Microsoft's P1 and P2 license.

• Single endpoint design with absolutely minimal attack surface
• Custom nginx config with strict input rules per above
• No stored Active Directory credentials, authorises against current user password only
• Rate limiting on per username basis
• Rate limiting on per IP basis
• Critical AD accounts blacklisted from access
• Ban bots (Google Recaptcha)
• Whitelist validation of input fields
• IP reputational lookup, banning proxy and Tor endpoints
• Static code analysis (utilising PEST)
• Encryption forced in AD communication
• Passwords checked with Pwned Passwords API for compromised
• API success and fail logged in

Example configuration implements the following:

• Only single endpoint forwarded to backend
• Limits access to POST
• Limits access to correct content type
• Rate limits by IP address
• Customises errors for friendly parsing by frontend (no HTML)
• Standard security headers

The following API keys are required to utilise this tool:

• Google Recaptcha
• IPHub

The file private.config should follow this format:

[
  {p3, [
      {captcha_key, <<"captcha">>},
      {domain_list, [ "domain1.lolware.net", "domain2.lolware.net" ]},
      {server_list, ["127.0.0.1"] },
      {iphub_key, <<"key">> }
  ]}
].

Frontend is a React based UI. The use of Google recaptcha was regrettably required, but no other Javascript or third party resources are utilised. The landing page is entirely self hosted.
