IE 0-day attack in-the-wild...
- https://krebsonsecur...-zero-day-flaw/
Dec 28th, 2012 - "Attackers are breaking into Microsoft Windows computers using a newly discovered vulnerability in Internet Explorer, security experts warn. While the flaw appears to have been used mainly in targeted attacks so far, this vulnerability could become more widely exploited if incorporated into commercial crimeware kits sold in the underground. In a blog posting* Friday evening, Milpitas, Calif. based security vendor FireEye said it found that the Web site for the Council on Foreign Relations was compromised and rigged to exploit a previously undocumented flaw in IE8 to install malicious software on vulnerable PCs used to browse the site. According to FireEye, the attack uses Adobe Flash to exploit a vulnerability in the latest (fully-patched) version of IE8..."
* http://blog.fireeye....ck-details.html
2012.12.28 - "... we received reports that the Council on Foreign Relations (CFR) website was compromised and hosting malicious content on or around 2:00 PM EST on Wednesday, December 26. Through our Malware Protection Cloud, we can confirm that the website was compromised at that time, but we can also confirm that the CFR website was also hosting the malicious content as early as Friday, December 21... We can also confirm that the malicious content hosted on the website does appear to use Adobe Flash to generate a heap spray attack against Internet Explorer version 8.0 (fully patched), which was the source of the zero-day vulnerability. We have chosen not to release the technical details of this exploit, as Microsoft is still investigating the vulnerability at this time... the JavaScript proceeded to load a flash file today.swf, which ultimately triggered a heap spray in Internet Explorer in order to complete the compromise of the endpoint..."
Update: "... We have seen multiple variations of this attack, as it looks like the attackers changed tactics multiple times during this campaign... Here is the decrypted payload.

MS Security Advisory (2794220)
Vulnerability in Internet Explorer Could Allow Remote Code Execution
- http://technet.micro...dvisory/2794220
Dec 29, 2012 - "Microsoft is investigating public reports of a vulnerability in IE6, IE7, and IE8. Internet Explorer 9 and Internet Explorer 10 are -not- affected by the vulnerability. Microsoft is aware of targeted attacks that attempt to exploit this vulnerability through Internet Explorer 8. The vulnerability is a remote code execution vulnerability that exists in the way that Internet Explorer accesses an object in memory that has been deleted or has not been properly allocated. The vulnerability may corrupt memory in a way that could allow an attacker to execute arbitrary code in the context of the current user within Internet Explorer. An attacker could host a specially crafted website that is designed to exploit this vulnerability through Internet Explorer and then convince a user to view the website. On completion of this investigation, Microsoft will take the appropriate action to protect our customers, which may include providing a solution through our monthly security update release process, or an out-of-cycle security update, depending on customer needs..."

The shim does not address the vulnerability but does prevent the vulnerability from being exploited for code execution... we’re working around the clock on the full security update. You should next expect to see an update from us announcing the availability of a Fix It tool to block the vulnerable code paths..."

IE 0-day - CMarkup Object Processing Flaw Lets Remote Users Execute Arbitrary Code
- http://www.securityt....com/id/1030266
CVE Reference: https://web.nvd.nist...d=CVE-2014-1770 - 9.3
Updated: Jun 10 2014
Impact: Execution of arbitrary code via network, User access via network
Vendor Confirmed:  Yes  
Version(s): 8; possibly other versions
Description: A vulnerability was reported in Microsoft Internet Explorer. A remote user can cause arbitrary code to be executed on the target user's system. A remote user can create specially crafted HTML that, when loaded by the target user, will trigger a memory error in the processing of CMarkup objects to execute arbitrary code on the target system. The code will run with the privileges of the target user.
The vendor was notified on October 11, 2013.
The original advisory is available at:
- http://zerodayinitia...ies/ZDI-14-140/
Solution: The vendor has issued a fix...
Vendor URL: https://technet.micr...curity/ms14-035
___

- https://atlas.arbor....ndex#1620714508
Elevated Severity
23 May 2014
A new zero-day vulnerability for Internet Explorer 8 has been disclosed.
Analysis: The flaw, which exists in the handling of CMarkup objects, could allow remote attackers to execute arbitrary code. Exploitation of this vulnerability requires user interaction, either by visiting a malicious site or opening a malicious file... The vulnerability is currently unpatched; it is recommended that users set Internet security zone settings to "High" to block ActiveX Controls and configure IE to prompt before running Active Scripting. Users should also ensure that Microsoft’s EMET (Enhanced Mitigation Experience Toolkit) is enabled.
