Independent researcher Reid Wightman of Digital Bond1 identified hard-coded credentials in the operating system of the ORing Industrial DIN-Rail Device Server 5042/5042+ systems and publicly released this information without coordination with ICS-CERT, the vendor, or any other coordinating entity known to ICS-CERT. This vulnerability grants attackers administrative access to the device. ICS-CERT has been unable to successfully coordinate this vulnerability with ORing Industrial Networking because of the vendor’s unresponsiveness. ICS-CERT is unaware of any fix by ORing Industrial Networking that mitigates this vulnerability.
This vulnerability can be exploited remotely. Exploits that target this vulnerability are known to be publicly available.
The following ORing Industrial Networking products are known to be affected:
Note: Other ORing Industrial Networking products may also be affected by this vulnerability.
Attackers can exploit the product by using the default hard-coded credential to log into the device with administrative privileges. Once access is gained, the attacker can read and write to files and change settings. This access level can impact the availability, integrity and confidentiality of the product.
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.
ORing Industrial Networking is based in Taiwan and maintains offices in several countries around the world, including the US, Korea, and China.
The affected products are industrial serial device servers used for SCADA systems. According to ORing’s Web site2 are deployed across several sectors including manufacturing, oil and gas, transportation, electric utilities, and others. ICS-CERT estimates that these products are used primarily in the United States, Europe, and Asia.
An attacker can log into the operating system of the device using an SSH connection with the root credentials to gain administrative access. Once the attacker gains access to the device, the file system and settings can be accessed, which could result in a loss of availability, integrity and confidentiality.
CVE-2012-45774 has been assigned to this vulnerability. A CVSS v2 base score of 10.0 has been assigned; the CVSS vector string is (AV:N/AC:L/Au:N/C:C/I:C/A:C).5
This vulnerability could be exploited remotely.
Exploits that target this vulnerability are publicly available.
An attacker with a low skill would be able to exploit this vulnerability.
ICS-CERT is not aware of ORing Industrial Networking developing a patch, update, or fix for the affected products. The ORing software update Web site6 does not indicate that a new version of firmware or security patch is available.
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. Several recommended practices are available for reading and download, including Improving Industrial Control Systems Cybersecurity with Defense-in-Depth Strategies.7 ICS-CERT reminds organizations to perform proper impact analysis and risk assessment prior to taking defensive measures.
Additional mitigation guidance and recommended practices are publicly available in the ICS-CERT Technical Information Paper, ICS-TIP-12-146-01A—Cyber Intrusion Mitigation Strategies.8
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.
