- ATTENTION: Exploitable from adjacent network
- Vendor: Becton, Dickinson and Company (BD)
- Equipment: BD Kiestra and InoqulA systems
- Vulnerabilities: Product UI does not Warn User of Unsafe Actions
2. RISK EVALUATION
Successful exploitation of these vulnerabilities may lead to loss or corruption of data.
3. TECHNICAL DETAILS
3.1 AFFECTED PRODUCTS
BD reports these vulnerabilities affect applications used by the following BD Kiestra systems:
- BD Kiestra TLA,
- BD Kiestra WCA, and
- BD InoqulA+ specimen processor.
All three BD Kiestra systems listed above use the following vulnerable applications:
- Database (DB) Manager, Version 18.104.22.168,
- ReadA Overview, Version 22.214.171.124 and previous, and
- PerformA, Version 126.96.36.199 and previous versions.
3.2 VULNERABILITY OVERVIEW
A vulnerability in DB Manager and PerformA allows an authorized user with access to a privileged account on a BD Kiestra system to issue SQL commands, which may result in data corruption.
A vulnerability in ReadA allows an authorized user with access to a privileged account on a BD Kiestra system to issue SQL commands, which may result in loss or corruption of data.
- Critical Infrastructure Sectors: Healthcare and Public Health
- Countries/Areas Deployed: Worldwide
- Company Headquarters Location: United States
BD discovered these vulnerabilities and reported them to NCCIC.
BD intends to implement necessary mitigation controls by July 2018. This mitigation will include removing the functionality to trigger SQL functions in DB Manager, PerformA and ReadA. Until mitigations are in place, BD recommends the following compensating controls. These controls require user action in order to reduce risk associated with these vulnerabilities:
- DB Manager:
- BD Kiestra Laboratory personnel should refrain from using the functionality associated SQL functions in all three BD Kiestra Systems: BD Kiestra TLA, BD Kiestra WCA and BD InoqulA+ specimen processor. When configuring new programs through the ‘Configuring Programs’ function in DB Manager, it is advised not to re-use current programs through the export-import function, but to set up a new program or use the predefined program templates. Please refer to the users manuals for more information.
- Ensure only authorized and qualified personnel, such as lab managers and/or lab supervisors, have access control rights to all functions in the DB Manager. This can be configured through the ‘Users’ function in DB Manager. For details about setting the appropriate user access control in DB Manager, consult the respective device manual.
- ReadA Overview: Users are advised to set the ‘Users’ function for all users to ‘none’ for access to ReadA Overview, if the application is not used or not commonly used. This can be configured through the ‘Users’ function in DB Manager. If use of ReadA Overview is necessary, users are advised to ensure only authorized and qualified personnel, such as lab managers and/or lab supervisors, have access control rights to all functions in ReadA Overview. This can be configured through the ‘Users’ function in DB Manager. For details about setting the appropriate user access control in DB Manager, consult the respective device manual.
- PerformA: Users are advised to ensure access to BD Kiestra servers are closely monitored while continuing to implement best security practices to effectively prevent unauthorized access to BD Kiestra Systems.

NCCIC recommends users take defensive measures to minimize the risk of exploitation of these vulnerabilities. Specifically, users should:
- Minimize network exposure for all control system devices and/or systems, and ensure that they are not accessible from the Internet.
- Locate control system networks and remote devices behind firewalls, and isolate them from the business network.
- When remote access is required, use secure methods, such as Virtual Private Networks (VPNs), recognizing that VPNs may have vulnerabilities and should be updated to the most current version available. Also recognize that VPN is only as secure as the connected devices.
NCCIC reminds organizations to perform proper impact analysis and risk assessment prior to deploying defensive measures.
NCCIC 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 on the ICS-CERT website in the Technical Information Paper, ICS-TIP-12-146-01B--Targeted Cyber Intrusion Detection and Mitigation Strategies.
Organizations observing any suspected malicious activity should follow their established internal procedures and report their findings to NCCIC for tracking and correlation against other incidents.
NCCIC also recommends that users take the following measures to protect themselves from social engineering attacks:
- Do not click web links or open unsolicited attachments in email messages.
- Refer to Recognizing and Avoiding Email Scams for more information on avoiding email scams.
- Refer to Avoiding Social Engineering and Phishing Attacks for more information on social engineering attacks.
No known public exploits specifically target these vulnerabilities. These vulnerabilities are not exploitable remotely. High skill level is needed to exploit.
