CoCo: Efficient Browser Extension Vulnerability Detection via Coverage-guided, Concurrent Abstract Interpretation

Jianjia Yu, Song Li, Junmin Zhu and Yinzhi Cao

CoCo interprets a browser extension abstractly but concurrently, one thread per branch, callback and message channel, scheduled to maximise code coverage, so it resolves dynamic JavaScript lookups prior tools missed. It found 43 zero-day flaws letting a web page message an extension to run code, send cross-origin AJAX bypassing SOP, download files, or read cookies, history and bookmarks.
