CVSS v3 5.0
Vendor: Mirion Technologies
Equipment: Telemetry Enabled Devices
Vulnerabilities: Use of Hard-Coded Cryptographic Key, Inadequate Encryption Strength
The following telemetry enabled devices are affected:
- DMC 3000 Transmitter Module,
- iPam Transmitter f/DMC 2000,
- RDS-31 iTX and variants (incl. RSD31-AM Package),
- DRM-1/2 and variants (incl. Solar PWR Package),
- DRM and RDS Based Boundary Monitors,
- External Transmitters,
- Telepole II, and
- MESH Repeater.
Successful exploitation of these vulnerabilities could allow an attacker to transmit fraudulent data or perform a denial of service.
Mirion Technologies recommends that users of 900 MHz devices compare data received with expected results and past results. Inconsistencies could indicate the presence of an interfering device.
Users of 2.4 GHz devices should contact Mirion Technologies for instructions to configure a unique encryption key where needed.
Mirion Technologies is continuing their investigation of this matter and expects to provide users with additional news and solutions in the next three months.
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.
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.
No known public exploits specifically target these vulnerabilities. These vulnerabilities are not remotely exploitable. High skill level is needed to exploit.
An unchangeable, factory-set key is included in the 900 MHz transmitter firmware.
Decryption of data is possible at the hardware level.
Ruben Santamarta of IOActive identified these vulnerabilities.
