Description
On Tapo
C520WS v2, restricted accounts (for example, hub users) are intended to execute
only a limited set of low‑sensitivity operations. Due to a logic flaw in the
device’s API authorization mechanism, an attacker can craft requests that
leverage legitimate “method mapping” behavior to bypass whitelist restrictions,
allowing restricted operations to be masked as permitted requests and executed.
Successful
exploitation may allow an attacker (with access to a restricted account) to
execute unauthorized sensitive operations.
Depending on the operation invoked, impact could include device
resets, unintended configuration changes, or disruption of normal operation,
leading to loss of availability and integrity of the device.

Title: Tapo C520WS v2 de TP-Link Systems, Description: En Tapo C520WS v2, las cuentas restringidas (por ejemplo, usuarios del hub) están destinadas a ejecutar solo un conjunto limitado de operaciones de baja sensibilidad. Debido a un fallo lógico en el mecanismo de autorización de la API del dispositivo, un atacante puede elaborar solicitudes que aprovechan el comportamiento legítimo de 'mapeo de métodos' para eludir las restricciones de la lista blanca, permitiendo que las operaciones restringidas se enmascaren como solicitudes permitidas y se ejecuten.
La explotación exitosa puede permitir a un atacante (con acceso a una cuenta restringida) ejecutar operaciones sensibles no autorizadas. Dependiendo de la operación invocada, el impacto podría incluir restablecimientos del dispositivo, cambios de configuración no deseados o interrupción del funcionamiento normal, lo que lleva a la pérdida de disponibilidad e integridad del dispositivo.
