CVE-2026-6241

An authenticated format string vulnerability is present in the ONVIF AddScopes in Tapo C520WS v2, where user-controlled input is improperly passed to formatting functions without adequate sanitization. An attacker can inject format specifiers into ONVIF scope parameters to manipulate memory handling behavior. Successful exploitation may cause the ONVIF management service to crash, resulting in DoS condition that impacts normal device operation.

Summary		(es) Una vulnerabilidad de cadena de formato autenticada está presente en los AddScopes de ONVIF en Tapo C520WS v2, donde la entrada controlada por el usuario se pasa incorrectamente a funciones de formato sin una sanitización adecuada. Un atacante puede inyectar especificadores de formato en los parámetros de alcance de ONVIF para manipular el comportamiento de manejo de memoria. La explotación exitosa puede causar que el servicio de gestión de ONVIF falle, lo que resulta en una condición de DoS que impacta el funcionamiento normal del dispositivo.
