A vulnerability in Sierra Wireless AirLink GX400, GX440, ES440, and LS300 routers with firmware before 4.4.7 and GX450, ES450, RV50, RV50X, MP70, and MP70E routers with firmware before 4.9.3 could allow an unauthenticated remote attacker to execute arbitrary code and gain full control of an affected system, including issuing commands with root privileges.

Security readout for executives and security teams

Plain-English summary

This flaw affects several Sierra Wireless AirLink routers. An unauthenticated remote attacker could execute arbitrary code and take full control, including root-level commands, on devices running older firmware. That makes exposed or operationally critical routers a serious business risk.

Executive priority

Prioritize remediation for internet-reachable, field, industrial, or connectivity-critical routers. Full device compromise could disrupt network operations and provide a foothold into connected environments.

Technical view

CVE-2018-10251 is an unauthenticated remote code execution vulnerability in specified AirLink router models before firmware 4.4.7 or 4.9.3, depending on model family. The CVE record states attackers could gain full system control with root privileges.

Likely exposure

Exposure is limited to organizations using the listed Sierra Wireless AirLink models with firmware below the fixed versions, especially where remote access is reachable from untrusted networks.

Exploitation context

The source bundle does not show CISA KEV listing or other evidence of active exploitation. The impact remains severe because the CVE describes unauthenticated remote code execution with root-level control.

Researcher notes

Public details in the bundle are sparse: no CVSS vector, CWE, exploit method, or detailed vulnerable component is provided. Analysis should remain focused on model and firmware validation unless vendor bulletin details are available.

Mitigation direction

  • Inventory listed Sierra Wireless AirLink router models across networks.
  • Upgrade GX400, GX440, ES440, and LS300 to firmware 4.4.7 or later.
  • Upgrade GX450, ES450, RV50, RV50X, MP70, and MP70E to firmware 4.9.3 or later.
  • Restrict remote access to router administration interfaces while remediation is verified.
  • Review Sierra Wireless guidance for model-specific update requirements.

Validation and detection

  • Confirm each router model and current firmware version.
  • Compare firmware against the affected thresholds in the CVE description.
  • Verify upgraded devices report firmware 4.4.7, 4.9.3, or later as applicable.
  • Check perimeter rules for unnecessary remote router access.
  • Review logs for unexpected administrative access or configuration changes.
