Executive Summary

CVE-2026-82703 is an authenticated OS command injection flaw in the Edimax BR-6214K router firmware version 1.40. The issue occurs in the /goform/asp_setPing endpoint where the pingstr parameter is not properly sanitized before being used in a shell command. This allows an authenticated attacker with web-management credentials to inject malicious shell commands and execute arbitrary OS commands with root privileges.

Detection Guidance

Check if your Edimax BR-6214K router is running firmware version 1.40. Test the /goform/asp_setPing endpoint by sending a crafted pingstr parameter with a harmless command like ;id;# to see if it executes. Monitor network traffic for unusual outbound connections or unexpected command outputs.

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. Since the Boa web server runs as root, the attacker could execute commands with the highest system privileges.

Compliance Impact

This vulnerability could lead to unauthorized access to sensitive data, violating GDPR and HIPAA requirements for data protection and access controls. Organizations using this router may face compliance violations, potential fines, and reputational damage due to compromised data integrity and confidentiality.

Mitigation Strategies

Immediately update the router firmware to the latest version if available. Disable remote management access to the router's web interface. Change default credentials to strong passwords. Block external access to the /goform/asp_setPing endpoint via firewall rules if possible.
