Loading vulnerability…
CVE-2008-0226 describes multiple buffer overflow vulnerabilities in yaSSL version 1.7.5 and earlier. The vulnerabilities exist in the ProcessOldClientHello function in handshake.cpp and the input_buffer& operator>> in yassl_imp.cpp. These flaws allow remote attackers to trigger buffer overflows by sending specially crafted input, potentially leading to arbitrary code execution. yaSSL is used in MySQL and possibly other products, making the impact more widespread.

This repository contains a single Metasploit module: 'MySQL yaSSL SSL Hello Message Buffer Overflow'. The exploit targets a stack buffer overflow vulnerability in the yaSSL library (version 1.7.5 and earlier) bundled with MySQL versions up to 6.0 on Linux. By sending a specially crafted SSL Hello packet to the MySQL service (default TCP port 3306), the module can trigger the overflow and execute arbitrary code with the privileges of the MySQL process. The module allows the attacker to select a payload (up to 100 bytes, avoiding certain bad characters) to be executed on the target. The exploit is operational and requires the target to be accessible over the network. The code is written in Ruby and is structured as a standard Metasploit exploit module, with all logic contained in a single file.
This repository contains a single Metasploit module (modules/exploits/windows/mysql/mysql_yassl_hello.rb) that exploits a stack buffer overflow vulnerability in the yaSSL library (version 1.7.5 and earlier) bundled with MySQL versions up to 6.0 on Windows. The exploit works by sending a specially crafted SSL Hello packet to the MySQL service running on TCP port 3306, triggering the overflow and allowing arbitrary code execution. The module supports custom payloads (up to 600 bytes) and targets specific MySQL versions (5.0.45-community-nt and 5.1.22-rc-community). The exploit is operational and leverages the Metasploit framework for payload delivery and session handling. No hardcoded IP addresses or domain names are present; the main fingerprintable endpoint is the MySQL TCP service on port 3306.
