CRITICAL 9.8

DescriptionCVE.org

Edimax EW-7438RPn-v3 Mini 1.27 contains a remote code execution vulnerability that allows unauthenticated attackers to execute arbitrary commands through the /goform/mp endpoint. Attackers can exploit the vulnerability by sending crafted POST requests with command injection payloads to download and execute malicious scripts on the device.

Executive ViewAI

Why It Matters

Edimax EW-7438RPn-v3 Mini wireless devices contain a critical remote code execution vulnerability (CVE-2020-37125, CVSS 9.8) that allows attackers to take complete control of affected equipment without authentication. Any organization deploying these access points faces immediate risk of network compromise, data exfiltration, and lateral movement into internal systems.

Business Impact: Severe

Compensating Controls

Implement network segmentation to isolate affected devices; deploy Web Application Firewall (WAF) rules to block POST requests to /goform/mp endpoint from external sources; disable remote management features if available; restrict network access to these devices via ACLs; consider complete air-gap or decommissioning until patch availability confirmed with vendor; monitor for exploitation attempts in network logs.
