Internet Explorer 8 0day

Posted May 6, 2013    BeyondTrust Research Team

Last week, news broke that the U.S. Department of Labor’s (DoL) website was compromised… and that it had been serving up Internet Explorer 0day to its visitors. This 0day, CVE-2013-1347 (Retina Audit 19041 – Microsoft Internet Explorer 8 Remote Code Execution Vulnerability (Zero-Day)), only affects Internet Explorer 8 on Windows XP, Vista, and Windows 7 (as well as Server 2003, 2008, and 2008 R2). However, the exploit used on the U.S. Department of Labor website only targeted Windows XP machines. Here’s what else you need to know:

Metasploit module available, targeting Windows XP, Server 2003, Vista, and Windows 7 (PowerBroker Endpoint Protection Platform detects and defeats this module)

• Blocking/disabling Active Scripting in both Internet and intranet zones mitigates exploitation

• Highly likely this vulnerability will be used by exploit packs in the immediate future

• Vulnerability based on reliable use-after-free condition (mshtml!CGenericElement)

• Grants arbitrary code execution within the context of the currently logged on user (least privilege environment, anyone?)

So what can you do right now to protect your organization? If possible, use another browser like Chrome or Firefox, disable Active Scripting if you still have to use IE8, do not run as Administrator, and finally, upgrade – Internet Explorer 9 and 10 are not vulnerable to this issue.

Update 5-9-2013: Microsoft has released a Fix it for this 0day.

8 Reasons Your Privileged Password Management Solution Will Fail

Posted September 18, 2014    Chris Burd

Leveraging complex, frequently updated passwords is a basic security best practice for protecting privileged accounts in your organization. But if passwords are such a no-brainer, why do two out of three data breaches tie back to poor password management? The fact is that not all privileged password management strategies are created equal, so it’s critical…

Posted September 11, 2014    Chris Burd

There are many things in life that get changed regularly:  your car oil, toothbrush and hopefully, your bed sheets.  It’s rare that you give these things much thought – even when you forget to change them. But what if you’re forgetting something that can cost you millions of dollars if left unchanged for long periods…
