CVSS v3 5.0

Vendor: Mirion Technologies

Equipment: Telemetry Enabled Devices

Vulnerabilities: Use of Hard-Coded Cryptographic Key, Inadequate Encryption
Strength

AFFECTED PRODUCTS

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,

    MESH Repeater.

IMPACT

Successful exploitation of these vulnerabilities could allow an attacker
to transmit fraudulent data or perform a denial of service.

MITIGATION

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.
