CVE-2014-1266 is an improper certificate validation flaw in Apple’s Secure Transport implementation, specifically in SSLVerifySignedServerKeyExchange in libsecurity_ssl/lib/sslKeyExchange.c. Due to an incorrect duplicated goto statement—the widely known "goto fail" bug—the code does not properly verify the signature on the TLS ServerKeyExchange message. As a result, the TLS handshake can succeed even when the server’s key exchange parameters are not legitimately signed by the certificate’s private key. A man-in-the-middle attacker can therefore present a certificate chain that appears acceptable while using an arbitrary private key for the signing step, or omit the signing step entirely, causing the client to accept a spoofed SSL/TLS server.

This repository is a proof-of-concept (POC) exploit for CVE-2014-1266, the Apple SSL/TLS certificate validation vulnerability affecting iOS and OS X. The repository contains two main Go files: 'main.go' implements a proxy server that listens on a configurable TCP port (default 8080) and intercepts HTTP and HTTPS requests from clients. It identifies vulnerable clients by matching their User-Agent headers against known affected iOS and OS X versions. When a vulnerable client is detected, the proxy hijacks the SSL connection and redirects it to a local HTTP server via a UNIX domain socket ('/tmp/apple-ssl.sock' by default). The 'http_server.go' file implements this local HTTP server, which serves a simple HTML page. The exploit demonstrates how an attacker could perform a man-in-the-middle attack against vulnerable Apple devices by exploiting the SSL verification flaw. The repository is structured as a standalone POC, requiring the attacker to configure the victim's proxy settings to point to the attacker's machine. No weaponized or automated exploitation is present; the code is for demonstration and educational purposes.
