Security Best Practices

CISA recommends users take defensive measures to minimize the risk of exploitation of these vulnerabilities, such as:

Minimize network exposure for all control system devices and/or systems, ensuring they are not accessible from the internet.
Locate control system networks and remote devices behind firewalls and isolating them from business networks.
When remote access is required, use more secure methods, such as Virtual Private Networks (VPNs), recognizing VPNs may have vulnerabilities and should be updated to the most current version available. Also recognize VPN is only as secure as the connected devices.

CISA reminds organizations to perform proper impact analysis and risk assessment prior to deploying defensive measures.

3.2 Vulnerability Overview

3.2.1 EXPOSURE OF SENSITIVE INFORMATION TO AN UNAUTHORIZED ACTOR CWE-200

The web server of the affected devices allow a low privileged user to access hashes and password salts of all system’s users, including admin users. An attacker could use the obtained information to brute force the passwords offline.

CVE-2023-52237 has been assigned to this vulnerability. A CVSS v3 base score of 7.5 has been calculated; the CVSS vector string is (CVSS:3.1/AV:N/AC:H/PR:L/UI:N/S:U/C:H/I:H/A:H).

A CVSS v4 score has also been calculated for CVE-2023-52237. A base score of 7.7 has been calculated; the CVSS vector string is (CVSS4.0/AV:N/AC:H/AT:P/PR:L/UI:N/VC:H/VI:H/VA:H/SC:N/SI:N/SA:N).

3.2.2 EXPOSURE OF SENSITIVE INFORMATION TO AN UNAUTHORIZED ACTOR CWE-200

The web server of the affected systems leaks the MACSEC key in clear text to a logged in user. An attacker with the credentials of a low privileged user could retrieve the MACSEC key and access (decrypt) the ethernet frames sent by authorized recipients.

CVE-2023-52238 has been assigned to this vulnerability. A CVSS v3 base score of 4.3 has been calculated; the CVSS vector string is (CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:L/I:N/A:N).

A CVSS v4 score has also been calculated for CVE-2023-52238. A base score of 2.3 has been calculated; the CVSS vector string is (CVSS4.0/AV:N/AC:L/AT:P/PR:L/UI:N/VC:L/VI:N/VA:N/SC:N/SI:N/SA:N).

3.2.3 INCORRECT PRIVILEGE ASSIGNMENT CWE-266

The affected products with IP forwarding enabled wrongly make available certain remote services in non-managed VLANs, even if these services are not intentionally activated. An attacker could leverage this vulnerability to create a remote shell to the affected system.

CVE-2024-38278 has been assigned to this vulnerability. A CVSS v3 base score of 6.6 has been calculated; the CVSS vector string is (CVSS:3.1/AV:N/AC:H/PR:H/UI:N/S:U/C:H/I:H/A:H).

A CVSS v4 score has also been calculated for CVE-2024-38278. A base score of 7.5 has been calculated; the CVSS vector string is (CVSS4.0/AV:N/AC:L/AT:P/PR:H/UI:N/VC:H/VI:H/VA:H/SC:N/SI:N/SA:N).

3.2.4 EXPOSURE OF SENSITIVE SYSTEM INFORMATION TO AN UNAUTHORIZED CONTROL SPHERE CWE-497

In some configurations, the affected products wrongly enable the Modbus service in non-managed VLANS. Only serial devices are affected by this vulnerability.

CVE-2024-39675 has been assigned to this vulnerability. A CVSS v3 base score of 8.8 has been calculated; the CVSS vector string is (CVSS:3.1/AV:A/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H).

A CVSS v4 score has also been calculated for CVE-2024-38278. A base score of 8.7 has been calculated; the CVSS vector string is (CVSS4.0/AV:A/AC:L/AT:N/PR:N/UI:N/VC:H/VI:H/VA:H/SC:N/SI:N/SA:N).

For more information see the associated Siemens security advisory SSA-928781 in HTML and CSAF.

CISA recommends users take defensive measures to minimize the risk of exploitation of these vulnerabilities, such as:

Minimize network exposure for all control system devices and/or systems, ensuring they are not accessible from the internet.
Locate control system networks and remote devices behind firewalls and isolating them from business networks.
When remote access is required, use more secure methods, such as Virtual Private Networks (VPNs), recognizing VPNs may have vulnerabilities and should be updated to the most current version available. Also recognize VPN is only as secure as the connected devices.

CISA reminds organizations to perform proper impact analysis and risk assessment prior to deploying defensive measures.
