Remote Code Execution Vulnerability in Siklu Etherhaul Products

CVE-2025-57174

What is CVE-2025-57174?

A significant vulnerability exists in Siklu Communications Etherhaul 8010TX and 1200FX devices, affecting firmware versions 7.4.0 through 10.7.3, and potentially other earlier versions. The rfpiped service listens on TCP port 555 and relies on static AES encryption keys that are hardcoded within the device's binary. These keys are uniform across all affected devices, enabling attackers to generate encrypted packets that can execute arbitrary commands without any form of authentication. This vulnerability represents a failed security patch for a previous CVE, indicating ongoing security risks within the Etherhaul series. System administrators and network security professionals should take immediate action to assess the potential impact on their environments.
