Research on Known Vulnerability Detection Method Based on Firmware Analysis

At present, the network security situation is becoming more and serious. Malicious attacks such as computer viruses, Trojans hacker are rampant. National group information war terrorism have a serious damage to production life of whole society. same time, with rapid development Internet Things arrival 5G era, IoT devices an important part industrial system, become target infiltration by hostile forces. This paper describes challenges facing firmware vulnerability detection at this stage, introduces four automatic utilization technologies in detail: based on patch comparison, control flow, data flow ROP attack against buffer vulnerabilities. On basis clarifying its core idea, main steps experimental results, limitations method proposed. Finally, combined methods, summarizes known analysis, looks forward follow-up work.
