How the Exploit Works

The attacker, given they have network access, uses a specific network protocol to initiate the exploit. This protocol allows the attacker to send requests directly to the PLC, bypassing any existing security measures. Once the communication is established, the attacker can send commands to read or write files on the PLC’s internal memory and memory card. This access, if used maliciously, can lead to system compromise and data leakage.

Conceptual Example Code

Here is a conceptual representation of how the vulnerability might be exploited:

GET /plc/memory HTTP/1.1
Host: target.example.com
{ "command": "read", "filename": "/etc/passwd" }

In this example, the attacker sends a GET request to the PLC’s memory endpoint. The command “read” is issued along with the filename “/etc/passwd”, which is a common target for attackers seeking to gain unauthorized access to a system.

Mitigation Guidance

The best way to mitigate the impact of this vulnerability is to apply the vendor patch as soon as it becomes available. Until then, using a Web Application Firewall (WAF) or an Intrusion Detection System (IDS) can serve as temporary mitigation. These systems can monitor network traffic and identify and block potential threats. Additionally, minimizing the number of people with network access to the PLCs can also help prevent exploitation.
