Microsoft Exchange Privilege Escalation Exploit



This module exploits a privilege escalation vulnerability found in Microsoft Exchange - CVE-2019-0724 Execution of the module will force Exchange to authenticate to an arbitrary URL over HTTP via the Exchange PushSubscription feature. This allows us to relay the NTLM authentication to a Domain Controller and authenticate with the privileges that Exchange is configured. The module is based on the work by @_dirkjan,

Module Options

To display the available options, load the module within the Metasploit console and run the commands 'show options' or 'show advanced':

msf > use auxiliary/scanner/http/exchange_web_server_pushsubscription
msf auxiliary(exchange_web_server_pushsubscription) > show actions
msf auxiliary(exchange_web_server_pushsubscription) > set ACTION < action-name >
msf auxiliary(exchange_web_server_pushsubscription) > show options
    ...show and set options...
msf auxiliary(exchange_web_server_pushsubscription) > run 

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.
