IoT devices from manufacturers have recently been affected due to major vulnerabilities in Zigbee protocol implementations. Security testing of Zigbee protocol implementations is becoming increasingly important. However, applying existing vulnerability detection techniques such as fuzzing to the Zigbee protocol is not a simple task. Dealing with low-level hardware events still remains a big challenge. For the Zigbee protocol, which communicates over a radio channel, many existing protocol fuzzing tools lack a sufficient execution environment.<\/jats:p>\n          <jats:p>\n            To narrow the gap, we designed\n            <jats:italic>Z-Fuzzer<\/jats:italic>\n            , a device-agnostic fuzzing tool for detecting security flaws in Zigbee protocol implementations. To simulate Zigbee protocol execution,\n            <jats:italic>Z-Fuzzer<\/jats:italic>\n            leverages a commercial embedded device simulator with pre-defined peripherals and hardware interrupt setups to interact with the fuzzing engine. Z-Fuzzer generates more high-quality test cases with code-coverage heuristics. We compare Z-Fuzzer with advanced protocol fuzzing tools, BooFuzz and Peach fuzzer, on top of Z-Fuzzer\u2019s simulation platform. Our findings suggest that Z-Fuzzer can achieve greater code coverage in Z-Stack, a widely used Zigbee protocol implementation. Compared to BooFuzz and Peach, Z-Fuzzer found more vulnerabilities with fewer test cases. Three of them have been assigned CVE IDs with high CVSS scores (7.5~8.2).\n          <\/jats:p>","DOI":"10.1145\/3551894","type":"journal-article","created":{"date-parts":[[2022,9,14]],"date-time":"2022-09-14T13:22:55Z","timestamp":1663161775000},"page":"1-24","update-policy":"https:\/\/doi.org\/10.1145\/crossmark-policy","source":"Crossref","is-referenced-by-count":9,"title":["Security Analysis of Zigbee Protocol Implementation via Device-agnostic Fuzzing"],"prefix":"10.1145","volume":"4","author":[{"ORCID":"https:\/\/orcid.org\/0000-0001-8548-3299","authenticated-orcid":false,"given":"Mengfei","family":"Ren","sequence":"first","affiliation":[{"name":"The University of Texas at Arlington, Arlington, Texas, USA"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-0425-8987","authenticated-orcid":false,"given":"Xiaolei","family":"Ren","sequence":"additional","affiliation":[{"name":"The University of Texas at Arlington, Arlington, Texas, USA"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-3613-1577","authenticated-orcid":false,"given":"Huadong","family":"Feng","sequence":"additional","affiliation":[{"name":"The University of Texas at Arlington, Arlington, Texas, USA"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-9682-0502","authenticated-orcid":false,"given":"Jiang","family":"Ming","sequence":"additional","affiliation":[{"name":"The University of Texas at Arlington, Arlington, Texas, USA"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-1069-5980","authenticated-orcid":false,"given":"Yu","family":"Lei","sequence":"additional","affiliation":[{"name":"The University of Texas at Arlington, Arlington, Texas, USA"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"320","published-online":{"date-parts":[[2023,3,7]]},"reference":[{"key":"e_1_3_3_2_2","first-page":"106","article-title":"The advantages of block-based protocol analysis for security testing","volume":"105","author":"Aitel Dave","year":"2002","unstructured":"Dave Aitel. 2002.
