LuaTaint: A Static Taint Analysis System for Web Interface Framework Vulnerability of IoT Devices
<|reference_start|>LuaTaint: A Static Taint Analysis System for Web Interface Framework Vulnerability of IoT Devices: IoT devices are currently facing continuous malicious attacks due to their widespread use. Among these IoT devices, web vulnerabilities are also widely exploited because of their inherent characteristics, such as improper permission controls and insecure interfaces. Recently, the embedded system web interface framework has become highly diverse, and specific vulnerabilities can arise if developers forget to detect user input parameters or if the detection process is not strict enough. Therefore, discovering vulnerabilities in the web interfaces of IoT devices accurately and comprehensively through an automated method is a major challenge. This paper aims to work out the challenge. We have developed an automated vulnerability detection system called LuaTaint for the typical web interface framework, LuCI. The system employs static taint analysis to address web security issues on mobile terminal platforms to ensure detection coverage. It integrates rules pertaining to page handler control logic within the taint detection process to improve its extensibility. We also implemented a post-processing step with the assistance of large language models to enhance accuracy and reduce the need for manual analysis. We have created a prototype of LuaTaint and tested it on 92 IoT firmwares from 8 well-known vendors. LuaTaint has discovered 68 unknown vulnerabilities.<|reference_end|>
