DescriptionCVE.org

Netis E1+ 1.2.32533 contains an information disclosure vulnerability that allows unauthenticated attackers to retrieve WiFi passwords through the netcore_get.cgi endpoint. Attackers can send a GET request to the endpoint to extract sensitive network credentials including SSID and WiFi passwords in plain text.

Executive ViewAI

Why It Matters

Netis E1+ routers are exposed to unauthenticated WiFi password theft, potentially compromising network access credentials and enabling lateral movement into corporate or personal networks. This vulnerability affects any organization or individual using this device model and requires immediate containment action due to active exploit availability and absence of vendor patches.

Business Impact: High
Compensating Controls

Disable remote management and netcore_get.cgi endpoint if possible through device configuration; implement network segmentation to restrict access to the device's web interface (port 80/443) to authorized personnel only; deploy WAF rules to block requests to /netcore_get.cgi; monitor network traffic for suspicious access patterns; require VPN access for any router management; consider replacing device with vendor that provides active security support.
