No fix is confirmed yet — apply a workaround or compensating control (WAF / firewall / segmentation) and watch for the fix.

CalAmp LMU 3030 series OBD-II CDMA and GSM devices has an SMS (text message) interface that can be deployed where no password is configured for this interface by the integrator / reseller. This interface must be password protected, otherwise, the attacker only needs to know the phone number of the device (via an IMSI Catcher, for example) to send administrative commands to the device. These commands can be used to provide ongoing, real-time access to the device and can configure parameters such as IP addresses, firewall rules, and passwords.

No fix is confirmed yet. Restrict network exposure of the affected system or apply the vendor's mitigation within your standard update timelines at low or medium mission impact and sooner than that at high, and watch the vendor's advisory for the fix.

Exploitation none (no KEV listing, exploit record or EPSS ≥ 50%) · Automatable unknown (not published for this CVE) · Technical impact partial (CVSS below 9.0). Mission impact is CISA's Mission & Well-being decision point, and only you can judge it: high means the affected system is essential to your organisation's mission, or its compromise could cause irreversible harm to people.
