Yokogawa STARDOM FCJ controllers R4.02 and prior, FCN-100 controllers R4.02 and prior, FCN-RTU controllers R4.02 and prior, and FCN-500 controllers R4.02 and prior utilize hard-coded credentials that could allow an attacker to gain unauthorized administrative access to the device, which could result in remote code execution.

Yokogawa STARDOM FCJ controllers R4.02 and prior, FCN-100 controllers R4.02 and prior, FCN-RTU controllers R4.02 and prior, and FCN-500 controllers R4.02 and prior utilize hard-coded credentials that could allow an attacker to gain unauthorized administrative access to the device, which could result in remote code execution.

The affected controllers utilize hard-coded credentials that could allow an attacker to gain unauthorized administrative access to the device, which could result in remote code execution.CVE-2018-10592 has been assigned to this vulnerability. A CVSS v3 base score of 9.8 has been calculated; the CVSS vector string is (AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H). The web application improperly protects credentials which could allow an attacker to obtain credentials for remote access to controllers.CVE-2018-17900 has been assigned to this vulnerability. A CVSS v3 base score of 9.4 has been calculated; the CVSS vector string is (AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:L). The application utilizes multiple methods of session management which could result in a denial of service to the remote management functions.CVE-2018-17902 has been assigned to this vulnerability. A CVSS v3 base score of 5.3 has been calculated; the CVSS vector string is (AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:L). The affected controllers utilize hard-coded credentials which may allow an attacker gain unauthorized access to the maintenance functions and obtain or modify information. This attack can be executed only during maintenance work.CVE-2018-17896 has been assigned to this vulnerability. A CVSS v3 base score of 8.3 has been calculated; the CVSS vector string is (AV:N/AC:L/PR:N/UI:R/S:U/C:H/I:H/A:L). The controller application fails to prevent memory exhaustion by unauthorized requests. This could allow an attacker to cause…
