CVE-2020-12483Network attack vector

App installation via exposed components and crafted parameters

Published Mar 23, 2021 · Updated Sep 16, 2024

Open redirect in vivo V-Appstore before 8.12.0.0 allows remote attackers to trigger app downloads and installations via crafted parameters. The exposed components accept crafted parameters that redirect the application into its download-and-install workflow; vivo has not identified the components or validation failure. No privileges are required, but user interaction is required; exploitation downloads and installs an attacker-selected app, with no reported service interruption.
