The following versions of Westermo EDW-100, a Serial to Ethernet converter, are affected:

• EDW-100: All versions

3.2 Vulnerability Overview

3.2.1 Use of Hard-coded Password CWE-259

Westermo EDW-100 has a hidden administrator account with a hardcoded password. In the firmware package, in "image.bin", the username root and the password for this account are both hard-coded and exposed as strings that can trivially be extracted. Currently there is no way to change this password.

CVE-2024-36080 has been assigned to this vulnerability. A CVSS v3.1 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).

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.

Westermo recommends replacing EDW-100 with Lynx DSS L105-S1. For further reference see 5-Port Managed Industrial Device Server Switch | L105-S1 ᐈ Westermo.

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

CISA has added one new vulnerability to its Known Exploited Vulnerabilities Catalog, based on evidence of active exploitation.

• CVE-2020-17519 Apache Flink Improper Access Control Vulnerability

These types of vulnerabilities are frequent attack vectors for malicious cyber actors and pose significant risks to the federal enterprise.

Binding Operational Directive (BOD) 22-01: Reducing the Significant Risk of Known Exploited Vulnerabilities established the Known Exploited Vulnerabilities Catalog as a living list of known Common Vulnerabilities and Exposures (CVEs) that carry significant risk to the federal enterprise. BOD 22-01 requires Federal Civilian Executive Branch (FCEB) agencies to remediate identified vulnerabilities by the due date to protect FCEB networks against active threats. See the BOD 22-01 Fact Sheet for more information.

Although BOD 22-01 only applies to FCEB agencies, CISA strongly urges all organizations to reduce their exposure to cyberattacks by prioritizing timely remediation of Catalog vulnerabilities as part of their vulnerability management practice. CISA will continue to add vulnerabilities to the catalog that meet the specified criteria.

3.4 RESEARCHER

Matt Wiseman of CISCO TALOS reported these vulnerabilities to AutomationDirect.

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.
