Independent researcher Karn Ganeshen has identified two vulnerabilities in the GE SNMP/Web Interface adapter. GE has produced a new firmware version to mitigate the identified vulnerabilities in later model devices. Earlier model SNMP/Web Interface adapters may need to be upgraded to accommodate the new firmware version to address the identified vulnerabilities.
These vulnerabilities could be exploited remotely.
The following SNMP/Web Interface adapter versions are affected:
Successful exploitation of these vulnerabilities may allow an attacker to execute arbitrary system commands and to access other usersβ sensitive account information potentially impacting the confidentiality, integrity, and availability of the system.
Impact to individual organizations depends on many factors that are unique to each organization. NCCIC/ICS-CERT recommends that organizations evaluate the impact of these vulnerabilities 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 product, SNMP/Web Interface adapter, is a web server designed to present information about the uninterruptible power supply (UPS). According to GE, the SNMP/Web Interface is deployed across several sectors including Critical Manufacturing and Energy. GE estimates that this product is used worldwide.
Device does not perform strict input validation, which may allow an authenticated user to execute any system commands on the system.

This web site will be active sometime after publication of this advisory. has been assigned to this vulnerability. A CVSS v3 base score of 6.5 has been assigned; the CVSS vector string is (AV:N/AC:L/PR:L/UI:N/S:U/C:H/I:N/A:N).CVSS Calculator, https://www.first.org/cvss/calculator/3.0#CVSS:3.0/AV:N/AC:L/PR:L/UI:N/S:U/C:H/I:N/A:N, web site last accessed February 2, 2016.
These vulnerabilities could be exploited remotely.
No known public exploits specifically target these vulnerabilities.
An attacker with a low skill would be able to exploit these vulnerabilities.
GE has released a new firmware version for the SNMP/Web Interface adapter, Version 4.8, which addresses the reported vulnerabilities. Firmware Version 4.8 can be applied to SNMP/Web Interface adapters with the following product numbers: 1024746, 1024747, 1024748, and 1024921.
GE reports that all other product numbers for SNMP/Web Interface adapters will need to be upgraded to the latest hardware version with Version 4.8 to address the identified vulnerabilities. GE recommends that users install the latest SNMP/Web Interface adapter with firmware Version 4.8. To obtain additional information about solution options, users can contact GE at the following email address:

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 ICSβCERT Technical Information Paper, ICS-TIP-12-146-01BβTargeted 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.
