CVE-2021-38828Public exploit

Network-traffic disclosure via missing transport encryption

Published Nov 14, 2022 · Updated Apr 30, 2025

Cleartext transmission in Xiongmai Camera XM-JPR2-LX firmware 4.02.R12.A6420987.10002.147502.00000 allows attackers to read network traffic. The camera transmits traffic without transport encryption, leaving intercepted packets readable in plaintext; the public record does not identify the protocol or exposed fields. Exploitation requires access to the camera's adjacent network path and exposes confidentiality only, with no documented ability to alter data or interrupt service.
