Loading vulnerability…
A stack-based buffer overflow exists in DoubleTake.exe, a component of HP StorageWorks Storage Mirroring (SWSM) prior to version 4.5 SP2. The vulnerability is triggered when the application processes a specially crafted encoded authentication request, leading to a buffer overflow on the stack. This flaw allows remote attackers to execute arbitrary code on the affected system.

This repository contains a single Metasploit module (modules/exploits/windows/misc/doubletake.rb) that exploits a stack buffer overflow vulnerability (CVE-2008-1661) in the authentication mechanism of NSI DoubleTake and HP StorageWorks Storage Mirroring Service. The exploit targets Windows systems running specific vulnerable versions (4.4.2, 4.5.0, 4.5.0.1819) of the software, connecting to the service on TCP port 1100. The module constructs a specially crafted authentication request that overflows a stack buffer, overwriting SEH and allowing execution of a customizable Metasploit payload (default space: 500 bytes, avoiding null bytes). The exploit is operational and provides remote code execution capabilities. The only fingerprintable endpoint is the TCP service on port 1100. The code is written in Ruby and is structured as a standard Metasploit exploit module.
