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.
