DescriptionCVE.org

Edimax EW-7438RPn 1.13 contains an information disclosure vulnerability that exposes WiFi network configuration details through the wlencrypt_wiz.asp file. Attackers can access the script to retrieve sensitive information including WiFi network name and plaintext password stored in device configuration variables.

Executive ViewAI

Why It Matters

The Ew-7438Rpn Mini wireless router (firmware versions up to 1.13) contains a critical credential protection flaw that could allow attackers to extract administrative credentials, potentially compromising network security. Organizations using this device face immediate risk of unauthorized access and network compromise, particularly concerning if deployed in production environments or handling sensitive data.

Business Impact: High

Compensating Controls

Since no patch is available: (1) Implement network segmentation to restrict access to the router's administrative interfaces via VPN or jump hosts only; (2) Disable remote management features if not required; (3) Deploy network-based intrusion detection to monitor for exploitation attempts; (4) Rotate credentials regularly and enforce strong password policies; (5) Monitor authentication logs for suspicious access patterns; (6) Consider device replacement with fully-supported alternatives as a long-term mitigation.
