CVE-2025-15257Public exploitNetwork attack vector

Unauthenticated command execution via unsanitized route fields

Published Dec 30, 2025 · Updated Dec 30, 2025

Command injection in Edimax BR-6208AC firmware 1.02 and 1.03 allows remote attackers to execute commands through static-route fields. The formRoute handler interpolates strIp, strMask, and strGateway directly into a route command with sprintf and passes the buffer to system without neutralizing shell metacharacters. No authentication or user interaction is required, and injected commands execute with the web service's privileges on the router.
