Loading vulnerability…
A remote code execution vulnerability exists in VBScript (versions 5.1, 5.6, 5.7, and 5.8) on Microsoft Windows 2000 SP4, XP SP2/SP3, and Server 2003 SP2, when used with Internet Explorer. The vulnerability is triggered when the MsgBox function in VBScript is called with a crafted .hlp file as the fourth argument (helpfile argument). If a user visits a malicious web page and presses the F1 key, winhlp32.exe is invoked with the attacker-supplied .hlp file, leading to arbitrary code execution.

This repository contains a single Metasploit module (ms10_022_ie_vbscript_winhlp32.rb) that exploits CVE-2010-0483, a code execution vulnerability in Microsoft Internet Explorer when handling VBScript MessageBox help functionality. The exploit works by serving a malicious web page via an HTTP server. When a user visits the page and presses F1 in response to a VBScript MessageBox, Internet Explorer attempts to load a help file (HLP) from a remote WebDAV server controlled by the attacker. The module implements both the HTTP and WebDAV servers, serving the malicious HLP file and a payload EXE (such as calc.exe or a custom Metasploit payload). The exploit targets Windows systems with vulnerable versions of Internet Explorer and requires user interaction (pressing F1). The code is written in Ruby and is fully integrated into the Metasploit framework, allowing for customizable payloads. The main entry point is the Ruby module file, which handles HTTP requests, WebDAV methods, and payload delivery.
