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-284: Improper access control
A network-adjacent authenticated attacker may perform unintended operations
CVSS v3: 5.5
CWE-321: Use of hard-coded cryptographic key
A network-adjacent unauthenticated attacker may log in to SFTP service and obtain and/or manipulate unauthorized files
CVSS v3: 5.4
CWE-522: Insufficiently protected credentials
A network-adjacent unauthenticated attacker may obtain sensitive information such as a username and its password in the address book
CVSS v3: 6.5
CWE-78: OS command injection
A network-adjacent authenticated attacker may execute an arbitrary OS command with root privileges by sending a specially crafted request
CVSS v3: 8.0
CWE-306: MISSING AUTHENTICATION FOR CRITICAL FUNCTION
The affected product is vulnerable to an attacker being able to use commands without providing a password which may allow an attacker to leak information.
Successful exploitation of these vulnerabilities could allow an attacker to perform remote code execution, impersonate and send false information, or bypass authentication.
Elvaco has not responded to requests to work with CISA to mitigate these vulnerabilities. Users of affected versions of M-Bus Metering Gateway CMe3100 are invited to contact Elvaco customer support for additional information.
CVSS v3: 7.5
