Loading vulnerability…
CVE-2014-0224 is a flaw in OpenSSL's handling of TLS ChangeCipherSpec (CCS) messages. OpenSSL before 0.9.8za, 1.0.0 before 1.0.0m, and 1.0.1 before 1.0.1h does not properly restrict CCS processing during the TLS handshake. A man-in-the-middle attacker can send a crafted handshake that causes vulnerable OpenSSL endpoints to derive and use weak keying material, described in the advisory as a zero-length master key, in certain OpenSSL-to-OpenSSL SSL/TLS sessions. This weakness affects both clients and certain servers and is commonly referred to as the "CCS Injection" vulnerability. The result is a break in the intended security of the TLS session, enabling compromise of confidentiality and integrity of the protected connection.

This repository is a proof-of-concept (PoC) exploit for CVE-2014-0224, a critical vulnerability in OpenSSL (1.0.1* series) that allows a man-in-the-middle (MITM) attacker to compromise SSL/TLS sessions via the Early ChangeCipherSpec attack. The repository contains two files: a README.md with setup instructions and references, and a Go program (proxy_all.go) that implements a MITM proxy. The proxy sits between a client and a server, both configured to use the RC4-SHA cipher, and manipulates the SSL/TLS handshake to exploit the vulnerability. The exploit requires the attacker to run the proxy, have the client connect to the proxy's listening port (default 9999), and have the proxy forward traffic to the target server (default 443). The code is a standalone PoC and does not belong to any exploit framework. It is intended for demonstration and research purposes, showing how the vulnerability can be exploited in practice. No hardcoded IPs or domains are present; all endpoints are configurable via command-line arguments.
