Summary

Siemens SIMATIC CN 4100

Notes

Summary

SIMATIC CN 4100 is vulnerable to authorization bypass through user-controlled key, use of default credentials and unauthenticated IP address change that could allow an attacker to remotely login as root or cause denial of service condition of the device. Siemens has released a new version for SIMATIC CN 4100 and recommends to update to the latest version.

General Recommendations

As a general security measure, Siemens strongly recommends to protect network access to devices with appropriate mechanisms. In order to operate the devices in a protected IT environment, Siemens recommends to configure the environment according to Siemens' operational guidelines for Industrial Security (Download: https://www.siemens.com/cert/operational-guidelines-industrial-security), and to follow the recommendations in the product manuals. Additional information on Industrial Security by Siemens can be found at: https://www.siemens.com/industrialsecurity

Recommended Practices

CISA recommends users take defensive measures to minimize the exploitation risk of this vulnerability.

Recommended Practices

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

Recommended Practices

Locate control system networks and remote devices behind firewalls and isolate them from business networks.

Recommended Practices

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 recent version available. Also recognize VPN is only as secure as its 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.

Summary

SSA-777015: Multiple Vulnerabilities in SIMATIC CN 4100 before V2.7

Notes

Summary

SIMATIC CN 4100 is vulnerable to authorization bypass through user-controlled key, use of default credentials and unauthenticated IP address change that could allow an attacker to remotely login as root or cause denial of service condition of the device. Siemens has released a new version for SIMATIC CN 4100 and recommends to update to the latest version.

General Recommendations

As a general security measure, Siemens strongly recommends to protect network access to devices with appropriate mechanisms. In order to operate the devices in a protected IT environment, Siemens recommends to configure the environment according to Siemens' operational guidelines for Industrial Security (Download: https://www.siemens.com/cert/operational-guidelines-industrial-security), and to follow the recommendations in the product manuals. Additional information on Industrial Security by Siemens can be found at: https://www.siemens.com/industrialsecurity
