Ichitaro Office is prone to a buffer-overflow vulnerability that occurs because it fails to perform adequate boundary checks on user-supplied data via a crafted .XLS document. This module runs a malicious web server on the Core Impact Console and waits for an unsuspecting user to trigger the exploit by connecting to it.
This module exploits a vulnerability in the WebEx extension for Chrome. The module will start a web server and serve a specially crafted page. The page will execute a series of PowerShell commands to download an executable file from Impact's web server and execute it. The vulnerability requires that the attack web page be served using HTTPS. See "Special comments" for futher detail.
