This repository contains proof of concept exploits for CVE-2024-5836 and CVE-2024-6778, which are vulnerabilities within the Chromium web browser which allowed for a sandbox escape from a browser extension. To run these, you must be on a version of Chromium older than 126.0.6478.54.
Write up: https://ading.dev/blog/posts/chrome_sandbox_escape.html
Bug report: https://issues.chromium.org/issues/338248595
Both the CVE-2024-5386 and CVE-2024-6778 directories contains a POC Chrome extension that is able to execute arbitrary JS on privileged WebUI pages. CVE-2024-5386 relies on a race condition and is fairly unreliable, while CVE-2024-6778 does not.
The sandbox-escape directory contains the full exploit chain, using CVE-2024-6778 to gain code execution in chrome://policy, which leads to a sandbox escape by setting the legacy browser support policies.
