Critical infrastructure sectors

Critical Manufacturing, Chemical, Energy, Water and Wastewater

Countries/areas deployed

Worldwide

Company headquarters location

Taiwan

Recommended Practices

CISA recommends users take defensive measures to minimize the exploitation risk of this (these) vulnerability(ies), such as:

Recommended Practices

Minimizing network exposure for all control system devices and/or systems, ensuring they are not accessible from the internet.

Recommended Practices

Locating control system networks and remote devices behind firewalls and isolating them from business networks.

Recommended Practices

When remote access is required, using more secure methods, such as Virtual Private Networks (VPNs). Recognize VPNs may have vulnerabilities, should be updated to the most recent version available, and are only as secure as the connected devices.

Recommended Practices

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

Recommended Practices

CISA also provides a section for control systems security recommended practices on the ICS webpage on cisa.gov. 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.

Recommended Practices

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 in the technical information paper, ICS-TIP-12-146-01B--Targeted Cyber Intrusion Detection and Mitigation Strategies.

Recommended Practices

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

Recommended Practices

No known public exploits specifically target this vulnerability.

9.8 (Critical) - CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H

Details

All versions prior to 9.1.4 of Advantech WebAccess/SCADA are vulnerable to use of untrusted pointers.
