VAR-202401-0196
Vulnerability from variot - Updated: 2025-12-18 00:09A vulnerability has been identified in SIMATIC CN 4100 (All versions < V2.7). The "intermediate installation" system state of the affected application allows an attacker to add their own login credentials to the device. This allows an attacker to remotely login as root and take control of the device even after the affected device is fully set up. SIMATIC CN 4100 is a communication node that can connect to third-party systems

VAR-202405-0204
Vulnerability from variot - Updated: 2025-08-27 20:26A 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. Siemens' simatic cn 4100 and SIMATIC CN 4100 A vulnerability exists in the firmware related to the use of hardcoded passwords.Information is obtained, information is tampered with, and service operation is interrupted. (DoS) It may be in a state. Siemens SIMATIC CN 4100 is a communication node of the German company Siemens
