Loading vulnerability…
CVE-2012-2686 is an invalid memory-access vulnerability in OpenSSL's AES-NI-accelerated AES-CBC/HMAC-SHA1 processing for TLS 1.1 and TLS 1.2. Processing specially crafted CBC-protected TLS data can cause the affected application to crash.

This repository contains a single Metasploit auxiliary module (modules/auxiliary/dos/ssl/openssl_aesni.rb) that exploits a denial of service (DoS) vulnerability in the AES-NI implementation of OpenSSL 1.0.1c (CVE-2012-2686). The exploit targets 64-bit systems running vulnerable OpenSSL versions with AES-NI enabled and supporting TLS 1.1 or above. The module crafts and sends specific TLS handshake and cipher suite negotiation packets to the target's SSL/TLS service (default port 443). If the target is vulnerable, the exploit triggers an integer underflow, causing the OpenSSL process to crash and resulting in a denial of service. The code is written in Ruby and is designed to be run within the Metasploit framework. The repository is structured as a single Ruby file, with all exploit logic contained within the Metasploit module class.
