Remote Communication Vulnerability in SICK LMS5xx by SICK AG

CVE-2023-4420

What is CVE-2023-4420?

The absence of Transport Layer Security (TLS) in SICK LMS5xx devices creates a security vulnerability that allows remote unauthenticated attackers to intercept communications. This lack of encryption facilitates unauthorized access to sensitive information, enabling potential eavesdropping and data manipulation during the exchange between the LMS5xx and client applications. Organizations using these devices must take immediate action to secure their communications against such threats.
