Loading vulnerability…
A buffer overflow vulnerability exists in SoftCart.exe, a component of Mercantec SoftCart 4.00b. The vulnerability is triggered when a remote attacker sends an HTTP GET request with an excessively long parameter, causing a buffer overflow condition. This can allow the attacker to overwrite memory and potentially execute arbitrary code on the affected system.

This repository contains a single Metasploit module (mercantec_softcart.rb) that exploits a buffer overflow vulnerability in the SoftCart.exe CGI component of Mercantec's SoftCart shopping cart software (version 4.00b) running on BSDi/4.3. The exploit works by sending a specially crafted HTTP GET request with a malformed CGI parameter to the SoftCart.exe endpoint (default: /cgi-bin/SoftCart.exe). The module includes brute-force capabilities to target a range of return addresses, increasing the likelihood of successful exploitation. The payload is customizable and allows for arbitrary code execution on the target system. The exploit is operational and requires the target to be running the vulnerable CGI script and accessible over the network. The code is written in Ruby and is structured as a standard Metasploit exploit module.
