How the Exploit Works

This vulnerability stems from improper neutralization of special elements used in an OS Command within the Honeywell MB-Secure software. An attacker can exploit this flaw by sending a specially crafted request containing malicious OS commands to the affected device. The system, failing to properly sanitize the input, executes the malicious commands, potentially leading to unauthorized system access, changes in configuration, or data exfiltration.

Conceptual Example Code

Here’s a conceptual example of how the vulnerability might be exploited:

POST /api/execute HTTP/1.1
Host: target.example.com
Content-Type: application/json
{ "command": "rm -rf / --no-preserve-root" }

In this example, the attacker sends a malicious POST request that instructs the system to delete all files in the root directory. Because the system fails to properly sanitize user inputs, it executes the command, leading to a catastrophic system failure.

Mitigation Guidance

The primary mitigation for this vulnerability is to apply the latest patch provided by Honeywell. The company recommends updating MB-Secure to version V12.53 or later and MB-Secure PRO to version V03.09 or later. In the absence of immediate patch application, temporary mitigation can be achieved by using a Web Application Firewall (WAF) or an Intrusion Detection System (IDS) to block or alert on suspicious activities and requests.
