How the Exploit Works
The exploit takes advantage of the alarm system’s lack of proper authentication measures. An attacker can capture and replay the authentication sequence, tricking the system into believing it’s a legitimate user. This allows the attacker to bypass the alarm system’s security measures and gain physical access to the protected facility without triggering any alarms.
Conceptual Example Code
Below is a conceptual example of how the vulnerability might be exploited. Note that this is a simplified example for understanding purposes and does not represent a real-world attack scenario.
capture = sniff(iface='eth0', filter='tcp and host 192.168.1.1 and port 80', count=1)
replay = send(capture)In this example, the ‘sniff’ function is used to capture the authentication sequence from the network interface ‘eth0’. The captured sequence is then replayed using the ‘send’ function, effectively bypassing the alarm system’s authentication measures.
