Authenticated command execution via L2TPUserName injection
Published May 3, 2026 · Updated May 3, 2026
Command injection in Edimax BR-6208AC 1.02 allows remote authenticated users to execute commands through the L2TP configuration interface. The setWAN function at /goform/setWAN incorporates the L2TPUserName parameter into an operating-system command without neutralizing command syntax. Access to the management interface and low-privilege authentication are required; successful exploitation can read, modify, or interrupt router data and services.
