A vulnerability was detected in Edimax BR-6208AC up to version 1.02. This vulnerability allows attackers to perform remote exploitation through a manipulation of the argument pptpDfGateway in the file /goform/setWAN. The resulting buffer overflow can lead to significant consequences for affected devices. Given the high CVSS score of 7.4, organizations utilizing these devices must take this issue seriously.
The exploit for this vulnerability is now public, which increases the urgency for organizations to address it. The vendor was contacted prior to the public disclosure but did not respond, leaving users at risk. Organizations should prioritize patching immediately to mitigate potential threats.
The vulnerability has been classified with a high severity due to its potential impacts on confidentiality, integrity, and availability. Attackers may leverage this vulnerability to gain unauthorized access or disrupt services, further emphasizing the need for a swift response.
Given the current status of this vulnerability, organizations using affected Edimax devices should schedule remediation within their priority patch cycle.
Vulnerability Details
The Edimax BR-6208AC router, up to version 1.02, is affected by a buffer overflow vulnerability. This vulnerability allows for remote exploitation via the file /goform/setWAN when the argument pptpDfGateway is manipulated. The CVSS score of 7.4 indicates a high severity, reflecting the potential for serious impacts on the device's operation.
The vulnerability falls under CWE-119 (Improper Restriction of Operations within the Bounds of a Memory Buffer) and CWE-120 (Buffer Copy without Checking Size of Input). The publication date for this vulnerability was May 3, 2026, and it remains classified as 'Received' with no response from the vendor.
Technical Analysis
The root cause of this vulnerability lies in improper handling of input within the specified file. When the pptpDfGateway argument is manipulated, it leads to a buffer overflow, allowing attackers to execute arbitrary code or disrupt the device's functionality. The attack vector is network-based, requiring low complexity with no user interaction needed.
This vulnerability requires low privileges for exploitation, making it accessible to a wider range of attackers. The impacts on confidentiality, integrity, and availability are high, indicating that successful exploitation could lead to significant disruption or unauthorized access.
Risk & Impact Analysis
Organizations using the Edimax BR-6208AC routers face a substantial risk due to this vulnerability. The network-accessible nature of the exploit means that attackers could potentially exploit the vulnerability from anywhere, increasing the blast radius of a successful attack.
The urgency of addressing this vulnerability is underscored by its CVSS score of 7.4, which classifies it as high severity. Organizations should not only patch the affected devices but also assess their overall security posture to prevent similar vulnerabilities in the future.
