Hozard Alarm System | v1.0

How the Exploit Works

The vulnerability in Hozard Alarm system v1.0 centers on the SMS authentication process. The system does not limit the number of attempts to bring it to a disarmed state. This lack of limitation opens the door for an attacker to perform a brute force attack on the SMS authentication mechanism. By continually attempting different codes, an attacker can eventually stumble upon the correct code and disarm the system. This leaves the premises unprotected and allows the attacker to gain unauthorized access without triggering the alarm.

Conceptual Example Code

While this vulnerability does not involve code execution, the concept of the attack can be illustrated with pseudocode:

# Pseudocode for Brute Force Attack on Hozard Alarm System
for attempt in range(MAX_ATTEMPTS):
# Generate a new code to try
code = generate_random_code()
# Send the code as an SMS to the alarm system
send_sms(alarm_system_number, code)
# Check the response to see if the system was disarmed
if check_response():
print("System disarmed on attempt #", attempt)
break

In the above pseudocode, an attacker generates random codes and sends them as SMS messages to the alarm system. This process continues until the correct code is found and the system is disarmed.

Mitigation Guidance

The most effective way to mitigate this vulnerability is by applying the vendor’s patch. The patch addresses this issue by implementing a limit on the number of attempts that can be made to disarm the system via SMS.
In the absence of a patch, using a Web Application Firewall (WAF) or an Intrusion Detection System (IDS) can provide temporary mitigation. These tools can detect and block suspicious activities, such as an unusually high number of SMS messages being sent to the alarm system, thereby preventing a brute force attack.
