Netis NX10 Firmware Information Disclosure Vulnerability

Executive Summary

Netis NX10 firmware versions V4.0.1.5808 and V3.0.0.4142 have an information disclosure vulnerability. Unauthenticated attackers can retrieve the administrator password by sending a request to the sysinfo action in the web management interface without a valid session. The exposed credential can then be used to gain full administrator access to the device.

Detection Guidance

To detect this vulnerability, scan for Netis NX10 devices on your network and check if they respond to a request to the sysinfo action in the web management interface. Use tools like curl to send a GET request to the vulnerable endpoint. Example command: curl http://<device_ip>/cgi-bin/sysinfo.cgi. If the device returns sensitive information including the administrator password, it is likely vulnerable.
