CVE-2025-40939 [MEDIUM] CWE-284 CVE-2025-40939: A vulnerability has been identified in SIMATIC CN 4100 (All versions < V4.0.1). The affected device A vulnerability has been identified in SIMATIC CN 4100 (All versions < V4.0.1). The affected device contains a USB port which allows unauthenticated connections. This could allow an attacker with physical access to the device to trigger reboot that could cause denial of service condition.

CVE-2025-40940 [MEDIUM] CWE-200 CVE-2025-40940: A vulnerability has been identified in SIMATIC CN 4100 (All versions < V4.0.1). The affected applica A vulnerability has been identified in SIMATIC CN 4100 (All versions < V4.0.1). The affected application exhibits inconsistent SNMP behavior, such as unexpected service availability and unreliable configuration handling across protocol versions. This could allow an attacker to access sensitive data, potentially leading to a breach of confidentiality

CVE-2025-40593 [HIGH] CWE-20 CVE-2025-40593: A vulnerability has been identified in SIMATIC CN 4100 (All versions < V4.0). The affected applicati A vulnerability has been identified in SIMATIC CN 4100 (All versions < V4.0). The affected application allows to control the device by storing arbitrary files in the SFTP folder of the device. This could allow an attacker to cause a denial of service condition.

CVE-2024-32740 [CRITICAL] CWE-798 CVE-2024-32740: A vulnerability has been identified in SIMATIC CN 4100 (All versions < V3.0). The affected device co A vulnerability has been identified in SIMATIC CN 4100 (All versions < V3.0). The affected device contains undocumented users and credentials. An attacker could misuse the credentials to compromise the device locally or over the network.

CVE-2024-32741 [CRITICAL] CWE-259 CVE-2024-32741: A vulnerability has been identified in SIMATIC CN 4100 (All versions < V3.0). The affected device co 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.

CVE-2024-32742 [HIGH] CWE-1326 CVE-2024-32742: A vulnerability has been identified in SIMATIC CN 4100 (All versions < V3.0). The affected device co A vulnerability has been identified in SIMATIC CN 4100 (All versions < V3.0). The affected device contains an unrestricted USB port. An attacker with local access to the device could potentially misuse the port for booting another operating system and gain complete read/write access to the filesystem.

CVE-2023-49621 [CRITICAL] CWE-1392 CVE-2023-49621: A vulnerability has been identified in SIMATIC CN 4100 (All versions < V2.7). The "intermediate inst A vulnerability has been identified in SIMATIC CN 4100 (All versions < V2.7). The "intermediate installation" system state of the affected application uses default credential with admin privileges. An attacker could use the credentials to gain complete control of the affected device.

CVE-2023-49251 [HIGH] CWE-639 CVE-2023-49251: A vulnerability has been identified in SIMATIC CN 4100 (All versions < V2.7). The "intermediate inst A 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.

CVE-2023-49252 [HIGH] CWE-20 CVE-2023-49252: A vulnerability has been identified in SIMATIC CN 4100 (All versions < V2.7). The affected applicati A vulnerability has been identified in SIMATIC CN 4100 (All versions < V2.7). The affected application allows IP configuration change without authentication to the device. This could allow an attacker to cause denial of service condition.

CVE-2023-29131 [HIGH] CWE-276 CVE-2023-29131: A vulnerability has been identified in SIMATIC CN 4100 (All versions < V2.5). Affected device consis A vulnerability has been identified in SIMATIC CN 4100 (All versions < V2.5). Affected device consists of an incorrect default value in the SSH configuration. This could allow an attacker to bypass network isolation.

CVE-2023-29130 [CRITICAL] CWE-284 CVE-2023-29130: A vulnerability has been identified in SIMATIC CN 4100 (All versions < V2.5). Affected device consis A vulnerability has been identified in SIMATIC CN 4100 (All versions < V2.5). Affected device consists of improper access controls in the configuration files that leads to privilege escalation. An attacker could gain admin access with this vulnerability leading to complete device control.
