CVE-2023-37456 is a vulnerability in Firefox for iOS prior to version 115, where the session restore helper component crashes if no parameter is sent to the message handler. This is likely due to insufficient validation of input parameters in the message handler routine, leading to a crash when it receives unexpected or missing data.

This repository contains a proof-of-concept (PoC) exploit for CVE-2023-37456. The repository consists of two files: a README.md with minimal information and a dos.html file containing the exploit code. The exploit is a simple HTML page with embedded JavaScript that attempts to send a message to the 'webkit.messageHandlers.sessionRestoreHelper' interface, which is typically available in WebKit-based browsers (such as Safari) under certain conditions. The purpose of this code is to trigger a vulnerability (likely a Denial of Service or similar issue) if the browser exposes this interface. There are no hardcoded network endpoints, but the exploit targets a specific JavaScript message handler, making it fingerprintable. The code is a minimal PoC and does not include any payload customization or advanced features.
