An unauthenticated attacker on the WAN interface, with the ability to intercept Dynamic DNS (DDNS) traffic between DDNS services and the modem, could manipulate specific responses

Published Apr 25, 2025 · corrected/updated Apr 25, 2025 · ViaSat RM5110 · evidence confidence high

An unauthenticated attacker on the WAN interface, with the ability to intercept Dynamic DNS (DDNS) traffic between DDNS services and the modem, could manipulate specific responses to include code that forces a buffer overflow on the modem. Customers that have not enabled Dynamic DNS on their modem are not vulnerable.

Grounded briefings

Catalog interpretations for three audiences. Each brief cites ingested metadata and the original advisories below. They are not independent research and they do not invent exploit steps.

Executive

CVE-2024-6199 is a high public vulnerability record for ViaSat RM5110. It is not currently listed in the CISA Known Exploited catalog. Check the linked vendor or CERT advisories for patch status. This summary is a catalog interpretation of the ingested metadata and cites the original advisories below.

System administrator

Identify whether ViaSat RM5110 is in your estate, then compare installed versions with the affected ranges. Affected packages or ranges on record: ViaSat RM5110 0 ≤4.3.0.2 (0 ≤4.3.0.2). Check the linked vendor or CERT advisories for patch status. Prefer the vendor or distribution advisory linked in Sources before changing production systems. This is a catalog interpretation, not a runbook.
