A security flaw has been discovered in Edimax BR-6208AC 1.02. The impacted element is the function setWAN of the file /goform/setWAN of the component L2TP Mode. The manipulation of the argument L2TPUserName results in command injection. It is possible to launch the attack remotely. The exploit has been released to the public and may be used for attacks. The vendor was contacted early about this disclosure but did not respond in any way.
With a CVSS score of 2.1, this vulnerability is classified as low severity. However, it is essential to acknowledge that even low-severity vulnerabilities can pose risks, especially if they are exploitable over a network. Risk to organizations includes potential unauthorized access and command execution.
Organizations should prioritize patching immediately. While the exploit is not widely known, the possibility of remote command injection remains a threat. It is advisable to monitor network traffic for any unusual activities that could indicate exploitation attempts.
This vulnerability represents a significant concern, particularly for devices in critical network environments. Organizations using the affected product should consult their vendor for guidance on remediation and consider implementing additional security measures.
Vulnerability Details
A security flaw has been discovered in Edimax BR-6208AC 1.02. The impacted element is the function setWAN of the file /goform/setWAN of the component L2TP Mode. The manipulation of the argument L2TPUserName results in command injection. It is possible to launch the attack remotely. The exploit has been released to the public and may be used for attacks.
The CVSS score is 2.1, which falls into the low severity category. The vulnerability may allow an attacker with low privileges to exploit the command injection and potentially execute arbitrary commands on the device.
Affected product: Edimax BR-6208AC 1.02. The publication date of this vulnerability is May 3, 2026.
Technical Analysis
The root cause of this vulnerability lies in the improper handling of user-supplied input within the setWAN function, allowing for command injection. It can be exploited through a network, with low complexity and no user interaction required.
Privileged access is required for exploitation, but since many devices may be inadequately secured, the potential for unauthorized access remains high. The vulnerability impacts confidentiality, integrity, and availability, albeit at a low level.
Risk & Impact Analysis
Real-world deployment risk is present as the vulnerability allows command injection that can be exploited remotely. Organizations using Edimax BR-6208AC should be aware of the potential impact on their network and devices.
The blast radius for this vulnerability could be significant if exploited, as it may allow attackers to gain control over affected devices. Organizations should assess their exposure and consider the urgency of addressing this vulnerability based on the CVSS score.
