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-345 INSUFFICIENT VERIFICATION OF DATA AUTHENTICITY:
In 2N Access Commander versions 3.1.1.2 and prior, a local attacker can escalate their privileges in the system which could allow for arbitrary code execution with root permissions.
Update to Access Commander version 3.2.
CVSS v3: 4.7
CWE-345 INSUFFICIENT VERIFICATION OF DATA AUTHENTICITY:
In 2N Access Commander versions 3.1.1.2 and prior, an Insufficient Verification of Data Authenticity vulnerability could allow an attacker to escalate their privileges and gain root access to the system.
Update to Access Commander version 3.2.
CVSS v3: 6.3
CWE-22 IMPROPER LIMITATION OF A PATHNAME TO A RESTRICTED DIRECTORY ('PATH TRAVERSAL'):
In 2N Access Commander versions 3.1.1.2 and prior, a Path Traversal vulnerability could allow an attacker to write files on the filesystem to achieve arbitrary remote code execution.
Update to Access Commander version 3.2.
CVSS v3: 7.2
CWE-290: AUTHENTICATION BYPASS BY SPOOFING
Snap One OVRC cloud uses the MAC address as an identifier to provide information when requested. An attacker can impersonate other devices by supplying enumerated MAC addresses and receive sensitive information about the device.

CVSS v3: 7.5
CWE-306: MISSING AUTHENTICATION FOR CRITICAL FUNCTION
A vulnerability exists in Snap One OVRC cloud where an attacker can impersonate a Hub device and send requests to claim and unclaimed devices. The attacker only needs to provide the MAC address of the targeted device and can make a request to unclaim it from its original connection and make a request to claim it.
OvrC Pro: All versions prior to 7.3 are affected.
