CVE-2020-37150 is a high-severity Insertion of Sensitive Information Into Sent Data (CWE-201) vulnerability in Edimax Ew-7438Rpn Mini Firmware. Its CVSS base score is 8.7 (High).
Operationally, exploitation aligns with the MITRE ATT&CK technique Exploit Public-Facing Application (T1190); ranked at the 50th 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 AC-14 (Permitted Actions Without Identification or Authentication) and AC-3 (Access Enforcement) — 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-2020-37150 is a vulnerability in the Edimax EW-7438RPn-v3 Mini firmware version 1.27 that permits unauthenticated access to the /wizard_reboot.asp page when the device is in unsetup mode. This endpoint discloses the Wi-Fi SSID and security key upon a simple GET request, resulting in exposure of sensitive information without requiring authentication. The issue is classified under CWE-201 (Exposure of Sensitive Information to an Unauthorized Actor) and carries a CVSS v3.1 base score of 7.5 (AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:N/A:N), highlighting high confidentiality impact from a network-based attack with low complexity.
Unauthenticated attackers with network access to the affected device can exploit this vulnerability by sending a GET request to the /wizard_reboot.asp endpoint. No user interaction or privileges are needed, allowing remote retrieval of the wireless password and SSID, which could enable unauthorized Wi-Fi network access or serve as a foothold for broader network reconnaissance and compromise.
Reference URLs include the Edimax product page for the EW-7438RPn Mini, an Exploit-DB entry (48318) detailing the exploit, and a VulnCheck advisory on the unauthorized Wi-Fi password disclosure in Edimax EW-RPN Mini devices. These resources document the issue but do not specify patches or mitigations in the provided information. Security practitioners should review them directly and consider isolating or updating affected devices.

Mitigating Controls (NIST 800-53 r5) AI
AC-14 explicitly identifies and authorizes actions permitted without identification or authentication, preventing unauthenticated access to sensitive endpoints like /wizard_reboot.asp that disclose Wi-Fi credentials.
AC-3 enforces approved authorizations for logical access to system resources, blocking unauthenticated GET requests to endpoints exposing sensitive Wi-Fi SSID and security key.
SI-15 filters information output to prevent unauthorized disclosure of sensitive data such as Wi-Fi credentials in responses from unauthenticated endpoints.
