CISA Adds Three Known Exploited Vulnerabilities to Catalog

CISA has added three new vulnerabilities to its Known Exploited Vulnerabilities (KEV) Catalog, based on evidence of active exploitation.

  • CVE-2024-54085 AMI MegaRAC SPx Authentication Bypass by Spoofing Vulnerability
  • CVE-2024-0769 D-Link DIR-859 Router Path Traversal Vulnerability
  • CVE-2019-6693 Fortinet FortiOS Use of Hard-Coded Credentials 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 KEV 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 KEV 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

Kaleris reported these vulnerabilities to CISA.

4. MITIGATIONS

Kaleris recommends users to implement the following versions or later:

  • Navis N4: Version 3.1.44+
  • Navis N4: Version 3.2.26+
  • Navis N4: Version 3.3.27+
  • Navis N4: Version 3.4.25+

  • Navis N4: Version 3.6.14+
  • Navis N4: Version 3.7.0+
  • Navis N4: Version 3.8.0+

If users are unable to update, Kaleris recommends following these mitigations:

  • If N4 does not need to be exposed to the internet, placing it behind a firewall.
  • If CAP needs to be exposed to the internet, disable the Ultra Light Client on the nodes being exposed. This can be done by blocking the Ultra Light Client URLs in the load balancer or firewall by blocking the following patterns: "url-pattern*.jnlp</url-pattern" and "url-pattern/ulc</url-pattern"
  • The Ultra Light Client endpoint can also be disabled on the N4 Cluster node by commenting out relevant code in the web.xml file and restarting the server.
  • If the Ultra Light Client must be exposed to the Internet, do one of the following:
    a. Set up a secure VPN connection to allow access for known external parties.
    b. Set up an authenticated jump system (Citrix, VDI, Etc.).
    c. Whitelist external allowed IPs. (least secure option)
  • Additionally, the following controls should be applied:
    a. Restrict the number of N4 nodes exposed to the internet.
    b. Ensure that HTTPS is enabled and configured on the filewall/loadbalancer.
    c. Use a reliable third-party party firewall with built in DDOS protection that can detect unwanted intrusions.
  • Users are required to implement TLS in their load balancer. The setup for this is included in the Application Security Guide that is provided to all users.
  • A final option to consider is upgrading to N4 4.0, where the Ultra Light Client has been fully replaced with the HTML UI.

Kaleris has sent a security advisory to all customers running Kaleris software.

3.4 RESEARCHER

Tomer Goldschmidt and Noam Moshe of Claroty Team82 reported these vulnerabilities to CISA.

The German Federal Office for Information Security (BSI) CERT-Bund assisted coordination with MICROSENS.

4. MITIGATIONS

MICROSENS recommends users to update to NMP Web+ Version 3.3.0 for Windows and Linux.

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.
