The rising numbers of vulnerabilities and security issues stemming from the rapid iteration and development of the Internet of Things (IoT) have introduced new challenges for the involved stakeholders to mitigate them in time. To effectively bring researchers, vendors, and end-users together to address such problems, Coordinated Vulnerability Disclosure (CVD) has become standard practice. Although general CVD procedures for practitioners to follow exist, adapting them to the specific circumstances has proven to be complicated in practice.

In this paper, we document our experience of reporting various security vulnerabilities for 15,820 IoT backends. The discovery and scanning have been part of a separate research project, in this contribution we focus on the disclosure to the backends’ operators in a large-scale coordinated vulnerability disclosure effort, following the latest disclosure guidelines. We discuss what we have learned to inform others who want to engage in large-scale CVD, we compare the steps and tradeoffs of our effort with current CVD suggestions, based on our measurement before and after the disclosure, and we describe how adapting our approach can improve CVD best practices.
