CVE-2026-6250
Full vulnerability record from the local CVENow database.
Description
An authenticated format string vulnerability exists in the ONVIF service of Tapo C110 v2 due to improper handling of user-controlled input. Externally controlled data is interpreted as a format string, which can be used to manipulate stack memory, including control flow data such as return addresses. A remote authenticated attacker may redirect execution flow to existing internal functions, triggering an unauthorized factory reset, leading to loss of configuration, deletion of stored credentials and service disruption.

Los datos controlados externamente se interpretan como una cadena de formato, que puede usarse para manipular la memoria de la pila, incluyendo datos de flujo de control como direcciones de retorno.\n\nUn atacante remoto autenticado puede redirigir el flujo de ejecución a funciones internas existentes, lo que desencadena un restablecimiento de fábrica no autorizado, lo que lleva a la pérdida de configuración, la eliminación de credenciales almacenadas y la interrupción del servicio."
