# CVE-2025-10585

This repository provides a proof-of-concept for a sandbox escape vulnerability chained with CVE-2025-10585, a type confusion flaw in Chrome's V8 engine. The focus here is solely on the sandbox escape component, assuming prior RCE within the renderer process (e.g., via V8 exploitation). This PoC targets Chrome versions prior to 140.0.7339.185 on Windows, macOS, and Linux, demonstrating how to bypass the renderer sandbox to achieve native code execution on the host system. It leverages a kernel-level interaction flaw in the Mojo IPC system combined with a utility process escalation.

The escape chain exploits weaknesses in Chrome's multi-process architecture, specifically the communication between the renderer and browser processes. This allows elevation from the sandboxed renderer to unsandboxed privileges, enabling file system access, process injection, or persistence mechanisms.

## Key Files and Structure
- **README.md**: Comprehensive guide on setup, prerequisites.
- **sandbox_escape.js**: JavaScript module that, post-V8 RCE, crafts malicious Mojo messages to trigger the escape. It manipulates IPC bindings to impersonate a privileged process and request elevated capabilities.
- **mojo_exploit.cc**: C++ source for a custom Mojo binder that exploits a race condition in capability negotiation, leading to unauthorized access to broker services.
- **payload_injector.py**: Python script to compile and inject the payload into a running Chrome instance for testing.
- **sandbox_bypass.wasm**: WebAssembly module for creating a controlled memory buffer used in the IPC overflow during the escape.
- **test_server.js**: Node.js server to host a minimal HTML page that loads the escape script after assuming RCE is achieved.

## Usage
1. Build the C++ components: Use CMake to compile `mojo_exploit.cc` for your platform.
2. Run the test server: `node test_server.js`
3. Launch vulnerable Chrome with flags: `chrome --no-sandbox --disable-gpu --user-data-dir=/tmp` (for debugging; remove --no-sandbox in real tests).
4. Navigate to http://localhost:8080/escape.html and monitor for successful escape indicators.
