Executive Summary

CVE-2026-82702 is an authenticated OS command injection flaw in the Edimax BR-6214K router firmware version 1.40. It exists in the /goform/asp_WlanMP endpoint where the ateFunc parameter is improperly sanitized and directly used in a shell command executed by the system() function. This allows authenticated attackers with web-management credentials to inject malicious shell commands and execute arbitrary OS commands with root privileges.

Detection Guidance

To detect this vulnerability, check if your Edimax BR-6214K router is running firmware version 1.40. Test the /goform/asp_WlanMP endpoint by sending a request with the ateFunc parameter containing a test payload like ';id;#' to see if arbitrary commands execute. Ensure authenticated access is required as the flaw allows command injection with root privileges.

Example curl command to test: curl -X POST 'http://<router-ip>/goform/asp_WlanMP' -d 'ateFunc=;id;#' -H 'Cookie: auth=YOUR_SESSION'

Impact Analysis

An attacker could gain full control of the router, allowing them to modify settings, intercept network traffic, install malware, or use the device as a pivot point for further attacks within the network. Since the Boa web server runs as root, the attacker gains root-level access.

Compliance Impact

This vulnerability could lead to unauthorized access to sensitive data, violating confidentiality requirements in GDPR and HIPAA. Compromised routers may expose protected health information or personal data, resulting in non-compliance and potential legal penalties.

Mitigation Strategies

Immediately update the Edimax BR-6214K router to the latest firmware if available. If no update exists, restrict access to the router's web interface by blocking external connections and changing default credentials. Disable remote management features and monitor network traffic for suspicious activity targeting the /goform/asp_WlanMP endpoint.
