What the vulnerability does

01Description

The Naxclow platform exposes a registration endpoint that accepts signed requests containing a batch prefix and an arbitrary caller-supplied account identifier, without validating any ownership relationship. Each call mints a new sequential device identifier and returns the current high-water counter value for the batch, allowing callers to measure and enumerate the active device space. The endpoint’s behavior enables precise fleet enumeration.
