GE has identified a hard-coded credential vulnerability in GE’s MultiLink series managed switches. GE has produced new firmware versions to mitigate this vulnerability.
This vulnerability could be exploited remotely.
The following MultiLink products are affected:
Exploitation of this vulnerability may allow an attacker to gain unauthorized administrative access to device configurations resulting in exposure and control of all configuration options available through the web interface.
Impact to individual organizations depends on many factors that are unique to each organization. NCCIC/ICS-CERT recommends that organizations evaluate the impact of this vulnerability based on their operational environment, architecture, and product implementation.
GE is a US-based company that maintains offices in several countries around the world.
The affected products, Multilink series switches, are managed Ethernet switches designed specifically for use in industrial facilities, substations, and transportation environments. According to GE, the Multilink series switches are deployed across several sectors including Critical Manufacturing, Energy, and Water and Wastewater Systems. GE estimates that these products are used worldwide.
The Multilink series switches have a hard-coded credential vulnerability, which could allow unauthorized administrative access to device configuration options available through the web interface.

ICS-CERT recommends that users take defensive measures to minimize the risk of exploitation of these vulnerabilities. Specifically, users should:
ICS-CERT reminds organizations to perform proper impact analysis and risk assessment prior to deploying defensive measures.
ICS-CERT also provides a section for control systems security recommended practices on the ICS-CERT web page at: http://ics-cert.us-cert.gov/content/recommended-practices. Several recommended practices are available for reading and download, including Improving Industrial Control Systems Cybersecurity with Defense-in-Depth Strategies.
Additional mitigation guidance and recommended practices are publicly available in the ICS‑CERT Technical Information Paper, ICS-TIP-12-146-01B–Targeted Cyber Intrusion Detection and Mitigation Strategies, that is available for download from the ICS-CERT web site (http://ics-cert.us-cert.gov/).
Organizations observing any suspected malicious activity should follow their established internal procedures and report their findings to ICS-CERT for tracking and correlation against other incidents.
