CVE-2012-4792 is a use-after-free vulnerability in Microsoft Internet Explorer 6, 7, and 8. Improper handling of uninitialized or deleted objects allows attacker-controlled web content to corrupt memory and execute arbitrary code. A demonstrated trigger frees an MSHTML CButton object while retaining a reference that is reused during page reload; another demonstration identifies a CDwnBindInfo object. Code executes in the current user's security context. Internet Explorer 9 and 10 are unaffected. The vulnerability was exploited in the wild in December 2012.

This repository contains a single Metasploit module (ie_cbutton_uaf.rb) that exploits a use-after-free vulnerability (CVE-2012-4792) in Microsoft Internet Explorer 8. The exploit targets Windows platforms (XP SP3, Vista, Server 2003, 7) and is triggered when a victim visits a malicious web page served by the attacker's HTTP server. The module uses JavaScript and ROP chains to achieve arbitrary code execution in the context of the user. The payload is fully customizable using Metasploit's payload system, typically resulting in a reverse shell or Meterpreter session. The module is weaponized, reliable, and part of the official Metasploit framework. No hardcoded IPs or domains are present; the main fingerprintable endpoint is the HTTP server hosting the exploit page.

A use-after-free vulnerability in Microsoft Internet Explorer 6–8 allows remote arbitrary code execution through a crafted website. The record explicitly reports exploitation in December 2012 and references watering-hole attacks involving the Council on Foreign Relations. References include public exploit code, Microsoft's MS13-008 security bulletin, and a Microsoft Fix it mitigation.
A use-after-free memory-corruption vulnerability in Internet Explorer 6, 7, and 8 allows arbitrary code execution with the current user's privileges when the user views specially crafted web content. Exploitation under an administrator account could give an attacker complete system control. The bulletin rates the flaw Critical on Windows clients and Moderate on Windows servers and reports targeted exploitation attempts against Internet Explorer 8. Internet Explorer 9 and 10 are unaffected. Microsoft released update KB2799329 through MS13-008 to correct object handling in memory. Documented mitigations include the MSHTML Shim Workaround, restricting Active Scripting and ActiveX, Internet Explorer Enhanced Security Configuration, EMET, and using accounts with fewer privileges.
A publicly disclosed memory-handling vulnerability in Internet Explorer 6, 7, and 8 can allow arbitrary code execution when a user views a specially crafted webpage. Code executes with the current user's privileges, potentially permitting complete system control when that user has administrative rights. The bulletin rates the vulnerability Critical on affected Windows clients and Moderate on affected Windows servers; Internet Explorer 9 and 10 are unaffected. Microsoft released MS13-008 (KB2799329) on January 14, 2013, to correct object handling in memory. Available mitigations include the MSHTML Shim Workaround, blocking Active Scripting and ActiveX controls, Internet Explorer Enhanced Security Configuration, EMET, and using nonadministrative accounts.
A use-after-free vulnerability in Microsoft Internet Explorer that could allow remote code execution. Microsoft completed its investigation of a public report and released security update MS13-008 on January 14, 2013. An earlier Microsoft Fix it solution, the MSHTML Shim Workaround, prevents exploitation.
