Email: Exchange version detection and fingerprinting

Description

Implement comprehensive Exchange Server version detection and detailed fingerprinting capabilities.

Detection Methods

1. SMTP Banner Analysis

   • Parse SMTP banner for version info
   • Extract server release date
   • Identify build number
   • Examples:
     • "Microsoft ESMTP MAIL Service Version..."
     • "Exchange 2016 RTM"
     • "Exchange Online"

2. HTTP Headers

   • OWA Server header
   • EWS endpoint version information
   • X-Powered-By headers
   • X-AspNet-Version

3. EWS Endpoint Analysis

   • Query /EWS/Exchange.asmx
   • Parse WSDL for version
   • Enumerate mailbox version
   • Detect server roles (Mailbox, CAS, DAG)

4. LDAP Detection

   • Query msDSMaximumCompatibilityLevel
   • Parse servicePrincipalName patterns
   • Identify global catalog servers
   • Version-specific AD attributes

5. ActiveSync Probing

   • EAS version negotiation
   • Device policy version
   • Server capabilities
