Detailsinfo

A vulnerability has been found in Naxclow Smart Doorbell X3, X Smart Home, V720 and ix cam (version now known) and classified as problematic. Affected by this vulnerability is some unknown processing of the component Device Identifier Handler. The manipulation with an unknown input leads to a generation of predictable numbers or identifiers vulnerability. The CWE definition for the vulnerability is CWE-340. The product uses a scheme that generates numbers or identifiers that are more predictable than required. As an impact it is known to affect confidentiality. The summary by CVE is:

Naxclow device identifiers use fixed manufacturing prefixes combined with sequential counters, producing a fully predictable and enumerable identifier space. Because the platform also exposes an endpoint that reveals the current identifier high-water mark, the active fleet can be enumerated.

The weakness was published by Temuri Takalandze as icsa-26-162-02. The advisory is shared at cisa.gov. This vulnerability is known as CVE-2026-42932 since 06/08/2026.
