NCCIC/ICS-CERT received a report from Trend Micro’s Zero Day Initiative (ZDI) concerning a credential management vulnerability in ABB’s DataManagerPro application. Security researcher Andrea Micalizzi reported this vulnerability to ZDI. ABB has produced a new version to mitigate this vulnerability.
ABB reports that the vulnerability affects the following versions of DataManagerPro:
- DataManagerPro, all versions: 1.0.0 to 1.7.0
An attacker who successfully exploits this vulnerability could insert and run arbitrary code on a computer where the affected product is used.
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.
ABB is a Switzerland-based company that maintains offices in several countries around the world.
The affected product, DataManagerPro, is data analysis software. According to ABB, DataManagerPro is deployed in the Energy, Food and Agriculture, and Water and Wastewater Systems sectors. ABB estimates that this product is used worldwide.
UNCONTROLLED SEARCH PATH ELEMENTa
An authenticated user may swap DLLs in the package directory to elevate permissions to administrator.
This vulnerability is not exploitable remotely and cannot be exploited without user interaction.
EXISTENCE OF EXPLOIT
No known public exploits specifically target this vulnerability.
An attacker with low skill would be able to exploit this vulnerability.
ABB has produced a new version (Version 1.7.1) to mitigate this vulnerability. ABB recommends that users apply the update at their earliest convenience. Users may find more information in ABB’s security advisory (ABB-VU-BUMP-089290) located on its web site at the following location:
ABB recommends security practices and firewall configurations to help protect systems from attacks that originate from outside the network. Such practices include:
- Carefully inspect any files transferred between computers, including scanning them with up‑to‑date antivirus software, so that only legitimate files may be transferred.
- User account management, appropriate authentificaton and permission management using the principle of least privilege.
More information on recommended practices can be found in the following ABB document:
3BSE032547, Whitepaper - Security for Industrial Automation and Control Systems
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. 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.
