Executive Summary

This vulnerability is an authenticated command injection flaw in the WAVLINK WN701AE router with firmware version M01AE_V260105. It exists in the ioos web backend, specifically in the del_staticrule function of the static_route_setting.sh file. The rule_name parameter is not properly sanitized before being passed to a system() call, allowing attackers to inject arbitrary commands.

Detection Guidance

To detect this vulnerability, check if your WAVLINK WN701AE router is running firmware version M01AE_V260105. Inspect the ioos web backend for the del_staticrule function and verify if the rule_name parameter is properly sanitized. Test by sending crafted HTTP requests with malicious input in rule_name to see if arbitrary commands are executed.

Commands to check firmware version: login to the router admin panel or use SSH to run 'cat /etc/version' or 'uname -a'. Monitor network traffic for unusual outbound connections or unexpected processes.

Impact Analysis

An attacker can exploit this to execute commands with root privileges on the device. This may lead to full device compromise, traffic interception, installation of persistent backdoors, lateral network movement, or recruitment into botnets for activities like DDoS attacks.

Mitigation Strategies

Immediately update the router firmware to the latest version if an update is available. Disable remote administration access to the router if not needed. Restrict access to the admin panel by IP whitelisting. Monitor logs for suspicious activity and consider isolating the router from critical network segments.
