Denial of Service Vulnerability in Socomec DIRIS Digiware M-70

CVE-2025-54850

What is CVE-2025-54850?

The Socomec DIRIS Digiware M-70 version 1.6.9 contains a vulnerability that exposes it to a denial of service attack. This occurs when an attacker sends a carefully crafted sequence of unauthenticated Modbus RTU over TCP packets to the device's port 503. By executing a series of commands to manipulate specific registers—first indicating a configuration change and then altering the Modbus address—the attacker effectively disrupts normal operations, leaving the device in a state where it cannot process legitimate requests.
