Executive Summary

This is a command injection vulnerability in D-Link DIR-825M routers running firmware v1.1.8. The flaw exists in the /boafrm/formSysCmd endpoint where the sysCmd parameter is passed directly to the system() function without any input validation. Attackers can inject shell commands via this parameter to execute arbitrary code with root privileges.

Detection Guidance

To detect this vulnerability, check if your D-Link DIR-825M router is running firmware version 1.1.8 or earlier. Send a crafted HTTP POST request to the /boafrm/formSysCmd endpoint with a test payload like '; sleep 5;' in the sysCmd parameter. If the response is delayed by 5 seconds, the device is likely vulnerable.

Impact Analysis

An attacker could exploit this to execute arbitrary commands on your router, potentially causing denial of service, taking over the device, modifying configurations, altering DNS settings, or intercepting network traffic. The exploit requires no authentication and can be performed remotely.

Mitigation Strategies

Immediately update the router firmware to the latest version if an update is available. If no update exists, consider replacing the device with a newer model that is no longer vulnerable. Disable remote administration features if not needed and restrict network access to the router's admin interface.
