CVE-2010-20123 is a stack-based buffer overflow in Steinberg MyMP3Player version 3.0 (build 3.0.0.67) triggered during parsing of .m3u playlist files. The application does not properly validate the length of attacker-controlled input contained in a playlist, which can cause a write past the bounds of a stack buffer and overwrite adjacent control data. By supplying a specially crafted .m3u file and inducing a user to open it in the vulnerable application, an attacker may corrupt execution state and achieve arbitrary code execution in the context of the user running MyMP3Player.

This repository contains a single Metasploit module targeting a stack buffer overflow vulnerability in Steinberg MyMP3Player version 3.0 (CVE-2010-20123). The exploit works by generating a specially crafted .m3u playlist file, which, when opened by the vulnerable application, triggers a buffer overflow allowing arbitrary code execution. The module allows the attacker to specify a payload (up to 900 bytes, avoiding certain bad characters), which is embedded in the malicious file. The exploit supports multiple return addresses for different Windows targets, including a SEH-based variant. The only fingerprintable endpoint is the crafted .m3u file itself. The repository is structured as a single Ruby file compatible with the Metasploit Framework, and its purpose is to provide a reliable method for exploiting this specific file format vulnerability for code execution on Windows systems running the affected software.
