Loading vulnerability…
Multiple stack-based buffer overflows exist in the Whale Client Components ActiveX control (WhlMgr.dll), as used in Microsoft Intelligent Application Gateway (IAG) prior to version 3.7 SP2. The vulnerabilities are triggered by passing overly long arguments to the CheckForUpdates or UpdateComponents methods, allowing for the possibility of arbitrary code execution.

This repository contains a single Metasploit module targeting a stack buffer overflow vulnerability (CVE-2007-2238) in the Microsoft Whale Intelligent Application Gateway Whale Client (WhlMgr.dll 3.1.502.64). The exploit is delivered via a malicious HTML page served by the Metasploit HTTP server. When a vulnerable client visits the page using Internet Explorer 6 or 7 on Windows XP or Vista, the exploit instantiates the 'ComponentManager.Installer.1' ActiveX object and calls its CheckForUpdates() method with an overly long string, triggering a buffer overflow. The module uses JavaScript heap spraying to deliver a customizable Metasploit payload (typically a shell) to achieve arbitrary code execution. The repository structure is typical for a Metasploit exploit module, with the main logic in 'modules/exploits/windows/browser/mswhale_checkforupdates.rb'. No external network endpoints are hardcoded; the exploit targets local ActiveX components via the browser.
