CVE-2024-6778 is a high-severity race condition in Chrome DevTools affecting Google Chrome versions prior to 126.0.6478.182. A crafted malicious Chrome extension can exploit the race to inject script or HTML content into a privileged Chrome page.

This repository provides proof-of-concept (POC) exploits for CVE-2024-5836 and CVE-2024-6778, both affecting the Chromium browser (including Chrome) prior to version 126.0.6478.54. The repository is organized into three main directories: 'CVE-2024-5836', 'CVE-2024-6778', and 'sandbox-escape'. Each directory contains a Chrome extension (manifest, devtools page, worker, and supporting files) that demonstrates exploitation of the respective vulnerability. - The 'CVE-2024-5836' and 'CVE-2024-6778' directories each contain a POC extension that abuses a race condition or permissions bypass in the Chrome DevTools API to inject arbitrary JavaScript into privileged WebUI pages (e.g., chrome://settings). - The 'sandbox-escape' directory contains a full exploit chain leveraging CVE-2024-6778 to gain code execution in the 'chrome://policy' page. The exploit sets malicious Chrome policies (such as 'AlternativeBrowserPath' and 'AlternativeBrowserParameters') to trigger the BrowserSwitcher feature, causing Chrome to launch a system executable (e.g., cmd.exe, bash, or Calculator) with attacker-controlled arguments. This results in a sandbox escape and arbitrary code execution on the host system. The exploit is operational and demonstrates a real-world attack chain from extension context to host code execution. The repository is well-structured, with each exploit as a standalone Chrome extension, and includes a README with detailed context and references. The main attack vector is via a malicious browser extension, and the exploit targets privileged Chrome WebUI endpoints and system executables as part of the payload.
