3.2 Vulnerability Overview

3.2.1 CLEARTEXT TRANSMISSION OF SENSITIVE INFORMATION CWE-319

The affected product utilizes a protocol that allows cleartext transmission of credentials. This could allow an attacker to retrieve these over the network and gain control of the PLC, but cryptographically secure authentication using the SRP-6a protocol is supported and recommended. Enabling authentication on the PLC prevents replay attacks, and requires the attacker to intercept and modify an active connection. Implementation of a non-routing control network also requires compromise of the network topology before SRTP packets can be intercepted.

CVE-2022-30263 has been assigned to this vulnerability. A CVSS v3.1 base score of 5.9 has been calculated; the CVSS vector string is (AV:P/AC:L/PR:N/UI:R/S:U/C:N/I:H/A:H).

A CVSS v4 score has also been calculated for CVE-2022-30263. A base score of 4.4 has been calculated; the CVSS vector string is (CVSS4.0/AV:P/AC:L/AT:P/PR:N/UI:A/VC:N/VI:H/VA:H/SC:N/SI:N/SA:N)

3.2.2 INSUFFICIENT VERIFICATION OF DATA AUTHENTICITY CWE-345

The affected products use the Winloader utility to manage firmware updates by serial port or a serial-over-Ethernet link that were found to not use authentication. This could allow an attacker to push malicious firmware images to the controller and cause a denial-of-service condition or allow remote code execution. This vulnerability only effects version of the CPE302, 205, and 310 that were produced before the “-Bxxx” hardware revisions.

CVE-2022-30268 has been assigned to this vulnerability. A CVSS v3.1 base score of 4.9 has been calculated; the CVSS vector string is (AV:P/AC:L/PR:L/UI:N/S:U/C:N/I:H/A:L).

A CVSS v4 score has also been calculated for CVE-2022-30268. A base score of 5.2 has been calculated; the CVSS vector string is (CVSS4.0/AV:P/AC:L/AT:N/PR:L/UI:N/VC:N/VI:H/VA:L/SC:N/SI:N/SA:N)

3.2.3 INSUFFICIENTLY PROTECTED CREDENTIALS CWE-522

The affected product uses a simple hashing scheme by client-side JavaScript. This could allow an attacker to intercept the hashes and strip the hashing scheme to obtain the credentials in plaintext. These credentials are only valid for 5 minutes due to the TLS protocol used, and also requires physical presence to press a button on the device, limiting this attack to being physically present and in a very short window. If this is accomplished, this only allows the attacker to upgrade or downgrade the firmware version. Due to this threat of Man-in-the-Middle attack, documentation recommends limiting physical access to networking equipment, and disabling IP routing on control networks. This vulnerability does not apply to older PLCs without a network-based update process.

CVE-2022-30266 has been assigned to this vulnerability. A CVSS v3.1 base score of 4.0 has been calculated; the CVSS vector string is (AV:P/AC:H/PR:N/UI:R/S:U/C:H/I:N/A:N).

A CVSS v4 score has also been calculated for CVE-2022-30266. A base score of 4.1 has been calculated; the CVSS vector string is (CVSS4.0/AV:P/AC:H/AT:N/PR:N/UI:A/VC:H/VI:N/VA:N/SC:N/SI:N/SA:N)

3.2.4 DOWNLOAD OF CODE WITHOUT INTEGRITY CHECK CWE-494

Control logic downloaded to the PLC, which can be either written in one of the IEC 61131-3 languages or written in C and supplied as an ELF binary block, is not cryptographically authenticated.

CVE-2022-30265 has been assigned to this vulnerability. A CVSS v3.1 base score of 4.4 has been calculated; the CVSS vector string is AV:L/AC:L/PR:H/UI:N/S:U/C:N/I:H/A:N).

A CVSS v4 score has also been calculated for CVE-2022-30265. A base score of 5.6 has been calculated; the CVSS vector string is (CVSS4.0/AV:L/AC:L/AT:P/PR:H/UI:N/VC:N/VI:H/VA:N/SC:N/SI:N/SA:N)

3.4 RESEARCHER

Nicolai Grødum and Sofia Lindqvist of PwC Norway reported these vulnerabilities to CISA.

4. MITIGATIONS

To mitigate the risks associated with these vulnerabilities, Westermo recommends:

Network segregation, perimeter protection, network to network protection, and physical security measures. EDW-100 functions as an industrial serial to ethernet converter. This means that EDW-100 does not in itself have any of the protective measures you require in a modern security posture, EDW-100 should not be placed at the edge of the network but instead deployed using the techniques mentioned in the IEC 62443 standard.

This means the use of network segregation and perimeter protection which can be accomplished by for example deploying a firewall and the use of VLANs.

If data needs to flow into, or out of, the security zone containing EDW-100 it is important to have network to network protection enabled which for example can be applied with a Virtual Private Network (VPN).

It is also crucial to have physical security measures put in place as the unit can be vulnerable to physical attacks and tampering. A recommendation to mitigate this risk is to place the unit in a separate enclosure with locks and alarms if it opened outside of normal maintenance.

While the unit’s design characteristics may necessitate extra precautions, implementing the suggested countermeasures ensures a secure deployment that effectively addresses associated risks.

4. MITIGATIONS

AutomationDirect recommends that users:

Update the Productivity Suite programming software to version 4.2.0.x or higher.
Update Productivity PLC’s firmware to the latest version.

Although Automation Networks and Systems come equipped with built-in password protection mechanisms, this represents a fraction of the security measures needed to safeguard these systems. It is imperative that Automation Control System Networks integrate data protection and security measures that match, if not exceed, the robustness of conventional business computer systems. AutomationDirect advises users of PLCs, HMI products, and SCADA systems to conduct a thorough network security analysis to ascertain the appropriate level of security necessary for their specific application.

AutomationDirect has identified the following mitigation for instances where systems cannot be upgraded to latest version:

Physically disconnect the PLC from any external networks, including the internet, local area networks (LANs), and other interconnected systems.
Configure network segmentation to isolate PLC from other devices and systems withing the organization.
Implement firewall rules or network access control (NAC) policies to block incoming and outgoing traffic to the PLC.

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.

CISA also provides a section for control systems security recommended practices on the ICS webpage on cisa.gov/ics. Several CISA products detailing cyber defense best practices are available for reading and download, including Improving Industrial Control Systems Cybersecurity with Defense-in-Depth Strategies.

CISA encourages organizations to implement recommended cybersecurity strategies for proactive defense of ICS assets.

Additional mitigation guidance and recommended practices are publicly available on the ICS webpage at cisa.gov/ics in the technical information paper, ICS-TIP-12-146-01B–Targeted Cyber Intrusion Detection and Mitigation Strategies.
