This updated advisory is a follow-up to the original advisory titled ICSA-14-202-01 OleumTech WIO Family Vulnerabilities that was published July 21, 2014, on the NCCIC/ICS-CERT web site.
Security researchers Lucas Apa and Carlos Mario Penagos Hollman of IOActive have identified multiple vulnerabilities in OleumTechβs WIO family including the sensors and the DH2 data collector. OleumTech has produced updates that mitigate these vulnerabilities. These vulnerabilities could be exploited remotely.
The following OleumTech Products are affected:
Two identified vulnerabilities may potentially allow a Man-in-the-Middle (MitM) attack to either monitor for reconnaissance or insert specially crafted data packets into the data stream. The third vulnerability can lead to a denial-of-service (DoS) condition under the correct circumstances.
Impact to individual organizations depends on many factors that are unique to each organization. ICS-CERT recommends that organizations evaluate the impact of this vulnerability based on their operational environment, architecture, and product implementation.
OleumTech is a US-based company headquartered in Foothill Ranch, California.
The affected products are part of the OleumTech WIO System, developed to provide end-to-end wireless remote monitoring infrastructure. According to OleumTech WIO products are deployed across several sectors including, Energy, Water and Wastewater Systems and others. OleumTech estimates that these products are used primarily in the United States and Canada.
If a specially crafted packet is received by the DH2 Gateway with a high value on the battery voltage field, the DH2 Gateway radio receiver crashes. If this scenario is repeated multiple times, a DoS condition could occur. This could allow the attacker to execute arbitrary code.
CVE-2014-2360NVD, http://web.nvd.nist.gov/view/vuln/detail?vulnId=CVE-2014-2360, web site last accessed May 21, 2015. has been assigned to this vulnerability. A CVSS v2 base score of 5.0 has been assigned; the CVSS vector string is (AV:N/AC:L/Au:N/C:N/I:N/A:P).CVSS Calculator, http://nvd.nist.gov/cvss.cfm?version=2&vector=AV:N/AC:L/Au:N/C:N/I:N/A:P, web site last accessed July 21, 2014.
When connecting any of the devices to BreeZ, it is possible to read the site security key of the device without authentication. This could allow someone, who has stolen a node or has physical access to the device to obtain the site security key to communicate freely with other network devices. However, this key cannot be read remotely when the data system is up and running, only in the manual setup mode. The data flow one way from sensor to gateway collector, and there is no control channel back to the sensor. To reset the key, the device must be taken offline and updated manually.
CVE-2014-2361NVD, http://web.nvd.nist.gov/view/vuln/detail?vulnId=CVE-2014-2361, web site last accessed May 21, 2015. has been assigned to this vulnerability. A CVSS v2 base score of 7.2 has been assigned; the CVSS vector string is (AV:L/AC:L/Au:N/C:C/I:C/A:C).CVSS Calculator, http://nvd.nist.gov/cvss.cfm?version=2&vector=AV:L/AC:L/Au:N/C:C/I:C/A:C, web site last accessed July 21, 2014.
The Site Security Key is generated using the function time64() from the standard C library. This is a 4-byte number that corresponds to the project creation calendar time. Using this value as a site security key could allow an unauthenticated device to guess the site key by trying a considerably low number of possible combinations.
CVE-2014-2362NVD, http://web.nvd.nist.gov/view/vuln/detail?vulnId=CVE-2014-2362, web site last accessed May 21, 2015. has been assigned to this vulnerability. A CVSS v2 base score of 7.8 has been assigned; the CVSS vector string is (AV:N/AC:M/Au:N/C:C/I:P/A:N).CVSS Calculator, http://nvd.nist.gov/cvss.cfm?version=2&vector=AV:N/AC:M/Au:N/C:C/I:P/A:N, web site last accessed July 21, 2014.
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.
OleumTech has created updates for both BreeZ and the gateway to mitigate all these vulnerabilities. These updates allow users to encrypt their wireless traffic with AES256.

ICS-CERT encourages asset owners to take additional defensive measures to protect against this and other cybersecurity risks.
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. ICS-CERT reminds organizations to perform proper impact analysis and risk assessment prior to deploying defensive measures.
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 NCCIC/ICS-CERT for tracking and correlation against other incidents.
In addition, ICS-CERT recommends that users take the following measures to protect themselves from social engineering attacks:
