Vulnerability Alert: 4-Digit PIN Insufficient Protection Against Brute-Force Attacks

CVE-2024-41798

What is CVE-2024-41798?

A significant security vulnerability exists in the SENTRON 7KM PAC3200, where the administrative access protection relies solely on a weak 4-digit PIN through the Modbus TCP interface. This limitation enables attackers to easily exploit this weakness through brute-force methods or by intercepting unencrypted Modbus communications. Such vulnerabilities highlight critical concerns for industrial control systems, underlining the need for enhanced security measures and more robust authentication methods to safeguard sensitive operational environments.
