CVE-2023-32346Network attack vector

Remote device enumeration via claim response discrepancy

Published May 22, 2023 · Updated Jan 16, 2025

Observable response discrepancy in Teltonika Remote Management System before 4.10.0 allows attackers to enumerate device identifiers remotely. The device-claim function returns different results for already-claimed serial numbers, already-claimed MAC addresses, and successful claims, allowing systematic list building. No authentication or user interaction is required; the bounded impact is disclosure of serial numbers and MAC addresses for devices connected to RMS, without integrity or availability effects.
