Loading vulnerability…
A buffer overflow vulnerability exists in MailCarrier 2.51 due to improper handling of input in the EHLO and possibly HELO SMTP commands. An attacker can exploit this by sending an overly long EHLO or HELO command to the MailCarrier SMTP service, causing a buffer overflow and potentially allowing execution of arbitrary code.

This repository contains a single Metasploit module targeting a stack buffer overflow vulnerability in the TABS MailCarrier v2.51 SMTP service (CVE-2004-1638). The exploit works by sending an overly long EHLO command to the SMTP service running on TCP port 25, overwriting the stack and allowing arbitrary code execution. The module supports multiple Windows targets (Windows 2000 and Windows XP, various service packs) and allows the attacker to specify a custom payload, such as a reverse shell or Meterpreter session. The exploit requires network access to the target's SMTP port and knowledge of the attacker's own LHOST for payload callback. The code is written in Ruby and is structured as a standard Metasploit exploit module, with options for RPORT and LHOST, and includes a check method to verify the presence of the vulnerable service.
