Lifecycle Timeline
2DescriptionCVE.org
A vulnerability was identified in Edimax BR-6208AC 1.02/1.03. Affected is the function formStaDrvSetup of the file /goform/formStaDrvSetup of the component Web-based Configuration Interface. The manipulation of the argument rootAPmac leads to command injection. Remote exploitation of the attack is possible. The exploit is publicly available and might be used. Edimax confirms this issue: "The product mentioned, EDIMAX BR-6208AC V2, has reached its End of Life (EOL) status. It is no longer supported or maintained by Edimax, and it is no longer available for purchase in the market. Consequently, there will be no further firmware updates or patches for this device. We recommend users upgrade to newer models for better security." This vulnerability only affects products that are no longer supported by the maintainer.
AnalysisAI
Command injection in the Edimax BR-6208AC V2 web-based configuration interface exposes unauthenticated remote attackers to arbitrary OS command execution by manipulating the rootAPmac parameter submitted to the /goform/formStaDrvSetup handler. Firmware versions 1.02 and 1.03 are confirmed affected, and Edimax has explicitly stated the device has reached End of Life with no firmware patch forthcoming - making this a permanent, unmitigable vulnerability for any unit still in service. A public proof-of-concept is available, and no public exploit identified at time of analysis in CISA KEV, though the 67th-percentile EPSS score suggests elevated risk relative to the broader CVE population.
Technical ContextAI
The Edimax BR-6208AC V2 is a consumer dual-band wireless router running embedded Linux-based firmware. The vulnerable endpoint /goform/formStaDrvSetup exposes the formStaDrvSetup C function through the device's web-based administration interface, likely used to configure station/repeater or WDS settings where rootAPmac specifies the upstream access point MAC address. The rootAPmac input is passed to an OS-level command without sanitization, constituting a CWE-74 (Injection) flaw - specifically an OS command injection where shell metacharacters embedded in the parameter cause the firmware to execute attacker-controlled commands. Affected versions are confirmed by CPE strings cpe:2.3:o:edimax:br-6208ac_firmware:1.02:*:*:*:*:*:*:* and cpe:2.3:o:edimax:br-6208ac_firmware:1.03:*:*:*:*:*:*:*. The CVSS 4.0 vector (AV:N/AC:L/AT:N/PR:N/UI:N) confirms the interface is network-accessible with no authentication barrier.
RemediationAI
No vendor-released patch identified at time of analysis - Edimax has explicitly confirmed that no firmware updates will be issued for the BR-6208AC V2 due to its EOL status, and recommends upgrading to a supported device. Device replacement is the only permanent fix. For devices that cannot be immediately retired, apply the following compensating controls: block all inbound access to the device's web management interface (typically TCP 80/443) from untrusted networks using upstream firewall rules or ACLs - this eliminates the network attack vector at the cost of disabling remote management; place the device behind a NAT boundary that does not forward management ports inbound; and disable any WDS or repeater mode if rootAPmac is only exercised in those configurations, which may limit the attack surface. Note that network-level blocking prevents exploitation but does not remove the underlying vulnerability and provides no protection against LAN-side attackers.
