  Since IoT systems provide services over the Internet, they must continue to
operate safely even if malicious users attack them. Since the computational
resources of edge devices connected to the IoT are limited, lightweight
platforms and network protocols are often used. Lightweight platforms and
network protocols are less resistant to attacks, increasing the risk that
developers will embed vulnerabilities. The code clone research community has
been developing approaches to fix buggy (e.g., vulnerable) clones
simultaneously. However, there has been little research on IoT-related
vulnerable clones. It is unclear whether existing code clone detection
techniques can perform simultaneous fixes of the vulnerable clones. In this
study, we first created two datasets of IoT-related vulnerable code. We then
conducted a preliminary investigation to show whether existing code clone
detection tools (e.g., NiCaD, CCFinderSW) are capable of detecting IoT-related
vulnerable clones by applying them to the created datasets. The preliminary
result shows that the existing tools can detect them partially.
