Naxclow IoT Platform Missing Authorization

CVSS Score

5.3

EPSS Score

0.0%

EPSS Percentile

0th

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.
