3. TECHNICAL DETAILS

3.1 AFFECTED PRODUCTS

The following Hughes Network Systems work streams are affected:

WL3000 Fusion Software: Versions prior to 2.7.0.10

3.2 Vulnerability Overview

3.2.1 INSUFFICIENTLY PROTECTED CREDENTIALS CWE-522

Credentials to access device configuration information stored unencrypted in flash memory. These credentials would allow read-only access to network configuration information and terminal configuration data.

CVE-2024-39278 has been assigned to this vulnerability. A CVSS v3.1 base score of 4.2 has been calculated; the CVSS vector string is (AV:P/AC:H/PR:N/UI:N/S:U/C:H/I:N/A:N).

A CVSS v4 score has also been calculated for CVE-2024-39278. A base score of 5.1 has been calculated; the CVSS vector string is (CVSS4.0/AV:P/AC:L/AT:N/PR:N/UI:N/VC:H/VI:N/VA:N/SC:N/SI:N/SA:N).

3.2.2 MISSING ENCRYPTION OF SENSITIVE DATA CWE-311

Credentials to access device configuration were transmitted using an unencrypted protocol. These credentials would allow read-only access to network configuration information and terminal configuration data.

CVE-2024-42495 has been assigned to this vulnerability. A CVSS v3.1 base score of 6.5 has been calculated; the CVSS vector string is (AV:A/AC:L/PR:N/UI:N/S:U/C:H/I:N/A:N).

A CVSS v4 score has also been calculated for CVE-2024-42495. A base score of 7.1 has been calculated; the CVSS vector string is (CVSS4.0/AV:A/AC:L/AT:N/PR:N/UI:N/VC:H/VI:N/VA:N/SC:N/SI:N/SA:N).

4. MITIGATIONS

Hughes Network Systems has patched the vulnerabilities, which requires no action by the user. Any questions or concerns should be directed to Hughes Network Systems customer support.

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.

Organizations observing suspected malicious activity should follow established internal procedures and report findings to CISA for tracking and correlation against other incidents.

No known public exploitation specifically targeting these vulnerabilities has been reported to CISA at this time. These vulnerabilities are not exploitable remotely.
