Zero-Day Exploit targeting Internet Explorer
Researchers at FireEye Research Labs have identified an Internet Explorer (IE) zero-day exploit that has been used in targeted attacks. This vulnerability will affect IE6 through IE 11 but targeted attacks have been specifically targeting IE 9, 10, and 11.
The vulnerability is a remote code execution vulnerability and exists in the way Internet Explorer accesses Flash objects in memory. In a web-based attack the attacker would host a web site that contains a webpage used to exploit the vulnerability the attacker would dupe victims into visiting the attack page by clicking links contained in an email or instant message.
According to researchers at FireEye there are steps administrators can take that will "break" the exploit. These include EMET 4.1 and 5.0 and using Enhanced Protected Mode in IE, available in IE 10 and 11.
The exploit requires the Adobe Flash plug-in to be present in the browser and disabling the Flash plug-in within IE will prevent the exploit from functioning.
To disable Flash in Internet Explorer
- Start Internet Explorer
- Go to Tools -> Manage Add-ons
- On the left side change the "Show" Drop Down List to All add-ons On the right side select the Adobe Shockwave Flash Player Click Disable
Official Reference: CVE-2014-0160
More Information: heartbleed.com
Researchers have recently announced that a flaw was uncovered in the OpenSSL software, one of the key technologies used to encrypt data transactions on many websites. This flaw is called the Heartbleed Bug.
Mitigation of the Heartbleed OpenSSL vulnerability requires three actions to ensure closing the threat. PaperClip's use of OpenSSL affected vcf4Life, vcf4Securities, vcf4Compliance and some VCF dedicated customers. eM4Compliant Email and Internet eXpress services were not affected.
- Patch OpenSSL
PaperClip has completed patching internal load balancers which utilize OpenSSL
Patch Completed on: Thursday, April 10,2014 @ 14:30 EST.
- Change SSL Certificates
PaperClip has submitted SSL Certificates change requests for all affected services and will apply them when they become available to us.
- Mandatory Password Change
PaperClip forced a system wide password reset event on Monday April 14, 2014 @ 09:00 EST. If you were not forced to change your password, this means your VCF platform was not affected.
Note: If you utilize our Microsoft Office Add-In, you will also need to change the password there to match the new password you created earlier.
These actions should conclude the recommended remediation for the Heartbleed OpenSSL threat. We appreciate your cooperation during this event.
