What is CVE-2025-27594?

The SICK DL100 devices employ an unencrypted proprietary protocol for data transmission and device authentication. This vulnerability allows attackers to intercept the authentication hash used during the login process. With this intercepted information, attackers can perform a pass-the-hash attack, gaining unauthorized access to the device. This poses significant risks as it could lead to the manipulation or disruption of device operations, underscoring the need for enhanced security measures and encryption protocols.
