Summary

CVE-2020-37149 is a medium-severity CSRF (CWE-352) vulnerability in Edimax Ew-7438Rpn Mini Firmware. Its CVSS base score is 5.1 (Medium).

Operationally, exploitation aligns with the MITRE ATT&CK technique Exploit Public-Facing Application (T1190); ranked at the 21th percentile by exploit likelihood (below the median); it is not currently listed in the CISA KEV catalog; a public proof-of-concept is referenced.

The strongest mitigations our analysis identified map to IA-11 (Re-authentication) and SC-23 (Session Authenticity) — see the control section below for these in your framework.

Synthesised by an AI model from the NVD description and linked references — a reading aid, not an authoritative source.

CVE-2020-37149 is a cross-site request forgery (CSRF) vulnerability, classified under CWE-352, affecting the Edimax EW-7438RPn-v3 Mini firmware version 1.27. It enables arbitrary command execution when an authenticated user is tricked into submitting a crafted form to the /goform/mp endpoint. The vulnerability has a CVSS v3.1 base score of 8.1 (AV:N/AC:L/PR:N/UI:R/S:U/C:N/I:H/A:H), indicating high severity due to network accessibility, low complexity, and significant impacts on integrity and availability.

An unauthenticated attacker can exploit this vulnerability remotely by luring an authenticated user to interact with a malicious webpage or link that automatically submits a forged POST request to the device's /goform/mp endpoint. This user interaction requirement (UI:R) allows the attacker, who needs no privileges (PR:N), to achieve arbitrary command execution on the device with the privileges of the tricked user, potentially compromising the Wi-Fi range extender's functionality.

MITRE ATT&CK Enterprise TechniquesAI

T1190 Exploit Public-Facing Application Initial Access
Adversaries may attempt to exploit a weakness in an Internet-facing host or system to initially access a network.
T1059.008 Network Device CLI Execution
Adversaries may abuse scripting or built-in command line interpreters (CLI) on network devices to execute malicious command and payloads.
Why these techniques?

CSRF in network device web UI directly enables remote arbitrary command execution on firmware (public-facing app exploitation + network device CLI).

Mitigating Controls (NIST 800-53 r5) AI

prevent

SC-23 requires mechanisms like anti-CSRF tokens to protect session authenticity, directly preventing forged requests to the /goform/mp endpoint from tricked authenticated users.

prevent

SI-10 mandates validation of information inputs such as crafted form data to the vulnerable endpoint, blocking arbitrary command execution.

prevent

IA-11 enforces re-authentication for high-risk actions like command execution, stopping CSRF exploits that leverage existing user sessions without further verification.
