Executive Summary

This vulnerability is a command injection flaw in the Edimax EW-7478APC 1.04 device. It exists in the setWAN function of the file /goform/setWAN. An attacker can manipulate the pppUserName, pptpUserName, or L2TPUserName arguments to execute arbitrary commands on the device. The attack can be performed remotely, and a public exploit is available.

Detection Guidance

This vulnerability involves command injection via the setWAN function in Edimax EW-7478APC firmware 1.04. Detection requires checking for exposed web interfaces on port 80 or 443 and testing the /goform/setWAN endpoint with crafted input to observe command execution behavior.

Impact Analysis

If you use the affected Edimax EW-7478APC 1.04 device, an attacker could gain unauthorized access to your network. They might execute commands to steal data, install malware, or disrupt network operations. Since the exploit is public, the risk of attack is higher.

Compliance Impact

This vulnerability involves command injection in Edimax EW-7478APC firmware, allowing remote attackers to execute arbitrary commands via manipulated user input fields. Such flaws can lead to unauthorized access, data exfiltration, or system compromise, which may violate data protection requirements under GDPR and HIPAA if sensitive information is exposed.

Mitigation Strategies

Immediately update the Edimax EW-7478APC firmware to the latest version if available. If no update exists, isolate the device from untrusted networks, disable remote access, and monitor network traffic for suspicious activity targeting the /goform/setWAN endpoint.
