How the Exploit Works
The exploit takes advantage of a flaw in the way Rockwell Automation Arena® handles DOE files. A skilled cyber attacker can create a maliciously crafted DOE file that forces the software to write beyond the boundaries of an allocated object. When a user opens this malicious file within the software, the vulnerability is exploited, allowing the cyber attacker to execute arbitrary code on the target system. However, to cause maximum damage, the software must run under the context of the administrator.
Conceptual Example Code
Below is a conceptual example of how the vulnerability might be exploited. Keep in mind, this is not a real exploit, but a simplified example to illustrate the concept:
using System;
using System.IO;
class Program
{
static void Main()
{
// Create a new DOE file with malicious payload.
string maliciousPayload = "..."; // Exploit code here.
File.WriteAllText("malicious.doe", maliciousPayload);
}
}In this example, a malicious DOE file is created with code that exploits the vulnerability in Rockwell Automation Arena®. When a user opens this file within the software, the malicious code is executed.
Mitigation and Future Prevention
To mitigate the risk of this vulnerability, users are advised to apply the vendor patch as soon as it’s available. In the meantime, using a Web Application Firewall (WAF) or an Intrusion Detection System (IDS) can provide temporary mitigation. Furthermore, avoid opening any untrusted or suspicious DOE files in Rockwell Automation Arena®. As a long-term measure, organizations are also recommended to implement a policy of least privilege, restricting administrative privileges only to those who absolutely require it.
