Team82 White Paper
Claroty researchers Sharon Brizinov and Tal Keren have uncovered six critical vulnerabilities in Wibu-Systems’ CodeMeter third-party license management component, which could expose OT environments across numerous industries to exploits via phishing campaigns or direct attacks. Like Ripple20, these vulnerabilities serve as a poignant example of how third-party components can be a significant—yet often overlooked—point of weakness within OT environments.
Adversaries could leverage the discovered vulnerabilities to modify existing software licenses or inject malicious ones, causing devices and processes to crash. These flaws also include serious encryption issues, which could allow attackers to execute code remotely and move laterally on OT networks.
CWE-547 USE OF HARD-CODED, SECURITY-RELEVANT CONSTANTS:
Optigo Networks Visual BACnet Capture Tool and Optigo Visual Networks Capture Tool version 3.1.2rc11 are vulnerable to an attacker impersonating the web application service and mislead victim clients.
Optigo Networks recommends users to upgrade to the following:
CVSS v3: 7.5
CWE-288 AUTHENTICATION BYPASS USING AN ALTERNATE PATH OR CHANNEL:
Optigo Networks Visual BACnet Capture Tool and Optigo Visual Networks Capture Tool version 3.1.2rc11 contain an exposed web management service that could allow an attacker to bypass authentication measures and gain controls over utilities within the products.
Optigo Networks recommends users to upgrade to the following:
CVSS v3: 9.8
CWE-547 USE OF HARD-CODED, SECURITY-RELEVANT CONSTANTS:
Optigo Networks Visual BACnet Capture Tool and Optigo Visual Networks Capture Tool version 3.1.2rc11 contain a hard coded secret key. This could allow an attacker to generate valid JWT (JSON Web Token) sessions.
Optigo Networks recommends users to upgrade to the following:
CVSS v3: 7.5
CWE-912 HIDDEN FUNCTIONALITY:
The "update" binary in the firmware of the affected product sends attempts to mount to a hard-coded, routable IP address, bypassing existing device network settings to do so. The function triggers if the 'C' button is pressed at a specific time during the boot process. If an attacker is able to control or impersonate this IP address, they could upload and overwrite files on the device.
Per FDA recommendation, CISA recommends users remove any Contec CMS8000 devices from their networks.
If asset owners cannot remove the devices from their networks, users should block 202.114.4.0/24 from their networks, or block 202.114.4.119 and 202.114.4.120.
Please note that this device may be re-labeled and sold by resellers.

CVSS v3: 7.5
CWE-295 IMPROPER CERTIFICATE VALIDATION:
The affected product is vulnerable due to failure of the update mechanism to verify the update server's certificate which could allow an attacker to alter network traffic and carry out a machine-in-the-middle attack (MITM). An attacker could modify the server's response and deliver a malicious update to the user.
Medixant recommends users download the v2025.1 or later version of their software.
CVSS v3: 5.7
