Loading vulnerability…
A stack-based buffer overflow exists in Eureka Email 2.2q, triggered when the client receives an excessively long error message from a remote POP3 server. The vulnerable function fails to properly validate the length of the error message before copying it to a stack buffer, allowing for overwriting of stack memory and potential execution of arbitrary code.

This repository contains a single Metasploit module (eureka_mail_err.rb) that exploits a buffer overflow vulnerability (CVE-2009-3837) in Eureka Email 2.2q (v2.2.0.1) for Windows. The exploit works by acting as a malicious POP3 server (default port 110) and sending an overly long -ERR response when the client connects and manually checks mail. The buffer overflow allows for remote code execution with a customizable Metasploit payload (up to 700 bytes). The exploit is not highly reliable, as the vulnerable code is only reached when the user manually checks mail (not at startup). The module targets Windows XP SP2/SP3 English systems and requires the attacker to control a POP3 server that the victim connects to. The code is written in Ruby and follows the standard Metasploit exploit module structure.
