Loading vulnerability…
A heap-based buffer overflow exists in the Remote Data Services (RDS) component of Microsoft Data Access Components (MDAC) versions 2.1 through 2.6, as well as Internet Explorer 5.01 through 6.0. The vulnerability is triggered by a malformed HTTP request sent to the Data Stub, which can result in memory corruption and potential code execution.

This repository contains a single Metasploit module (ms02_065_msadc.rb) that exploits a heap overflow vulnerability in Microsoft IIS servers running MDAC (Microsoft Data Access Components) 2.1 through 2.6, specifically in the /msadc/msadcs.dll endpoint. The exploit targets the RDS DataStub 'Content-Type' header, sending an overly long value to trigger the overflow and execute arbitrary code. The module is weaponized, supporting customizable payloads (defaulting to a reverse shell) and targeting multiple language versions of Windows 2000 Professional. The attack vector is network-based, requiring HTTP access to the vulnerable endpoint. The code is written in Ruby and is structured as a standard Metasploit exploit module, with options for target URI and payload selection. The main fingerprintable endpoints are /msadc/msadcs.dll and /msadc/msadcs.dll/AdvancedDataFactory.Query.
