CVE-2020-25169Network attack vector

Camera-feed disclosure via cleartext P2P transport

Published Jan 26, 2021 · Updated Sep 16, 2024

Cleartext transmission in Reolink P2P products allows remote attackers to read camera feeds exchanged with Reolink servers. The P2P protocol sends data between each local camera or recorder and Reolink servers without sufficient confidentiality protection, leaving captured video readable in transit. No authentication or user interaction is required; access to the exposed network exchange discloses surveillance footage, with no substantiated availability impact.
