Loading vulnerability…
Csound versions prior to 5.16.6 contain multiple stack-based buffer overflow vulnerabilities in the getnum function, present in util/heti_main.c and util/pv_import.c. These vulnerabilities can be triggered by supplying a specially crafted hetro or PVOC file, leading to a buffer overflow on the stack.

This repository contains a single Metasploit module (Ruby file) that exploits a stack buffer overflow vulnerability in Csound (before version 5.16.6) when importing a specially crafted hetro file. The exploit targets Windows XP SP3 and Windows 7 SP1 platforms. The module generates a malicious .csd file (default name: msf.csd) that, when imported by the vulnerable Csound application using the 'csound -U het_import' command, triggers the buffer overflow and executes arbitrary code provided by the Metasploit payload system. The exploit is operational and allows for customizable payloads, but requires user interaction to import the malicious file. No network endpoints are involved; the attack vector is local file import. The repository is structured as a standard Metasploit exploit module and is intended for use within the Metasploit framework.
