Official Description

A vulnerability has been identified in SIMATIC CN 4100 (All versions < V3.0). The affected device contains hard coded password which is used for the privileged system user `root` and for the boot loader `GRUB` by default . An attacker who manages to crack the password hash gains root access to the device.

Source: NIST NVD / MITRE CVE Database

Attack Vector Analysis — CITED Relevance

The vulnerability allows an attacker to exploit hard-coded credentials for the root user and GRUB bootloader. If an attacker gains access to the password hash, they can use it to obtain root access to the device, leading to complete control over the system. This can result in unauthorized modifications, data exfiltration, and potential disruption of operations.
