Summary
This is a remotely exploitable buffer overflow vulnerability in the /goform/setWAN endpoint of the widely used Edimax BR-6428nC wireless router. An unauthenticated attacker can trigger the flaw by sending a maliciously crafted request with an overlong pptpDfGateway argument. Successful exploitation can lead to remote code execution or denial of service on the affected device. The vendor has not responded to disclosure efforts to resolve the issue.
Remediation
Disable remote management access to the router web interface if it is not required. Restrict access to the interface to only trusted local network devices. Users should plan to replace the device if no official firmware update is ever released by the vendor.
