Version Summary:

Microsoft Internet Explorer contains a vulnerability that could allow an unauthenticated, remote attacker to execute arbitrary code. Updates are available.

 
 
Description

Microsoft Internet Explorer contains a vulnerability that could allow an unauthenticated, remote attacker to execute arbitrary code on a targeted system.

The vulnerability is due to improper processing when printing specially crafted HTML content in Internet Explorer. An unauthenticated, remote attacker could exploit the vulnerability by convincing a user to visit a malicious site and print a crafted page. If successful, the attacker could execute arbitrary code on the system.

Microsoft has confirmed the vulnerability in a security bulletin and released software updates.

IntelliShield Analysis

To exploit the vulnerability, the attacker may provide a file or a link to a malicious website and use misleading language or instructions to persuade the user to open the file or follow the provided link.

Microsoft has corrected this vulnerability by modifying the way Internet Explorer handles printing crafted HTML content.

The Cisco Applied Intelligence team has created an Applied Mitigation Bulletin to address vulnerabilities that Microsoft disclosed in the April 2012 security bulletin release. This Cisco bulletin, which assists administrators in identifying or mitigating these vulnerabilities using Cisco devices, is available at the following link: Cisco Applied Mitigation Bulletin: Microsoft Security Bulletin Release for April 2012.

Impact

An unauthenticated, remote attacker could exploit this vulnerability to execute arbitrary code on a targeted system with the privileges of the user. If the user holds elevated privileges, the attacker could completely compromise the system.

 
Technical Information

The vulnerability is due to improper handling of crafted HTML content by the affected software. The vulnerability exists when the affected software attempts to print a specially crafted HTML page. Attempting to print the malicious page could cause an error that may allow arbitrary code execution.

An unauthenticated, remote attacker could exploit this vulnerability by convincing a user to view a website that contains crafted HTML content and then convincing the user to print the malicious page with the Print table of links option enabled. When processed, the malicious content could cause Internet Explorer to execute arbitrary code. Also, the attacker could embed an ActiveX control marked safe for initialization in an application or Office document that uses the Internet Explorer rendering engine. The attacker could take advantage of the error to execute arbitrary code on the system with the privileges of the user.

 
Safeguards

Administrators are advised to apply the appropriate updates.

Users are advised not to open e-mail messages from suspicious or unrecognized sources. If users cannot verify that links or attachments included in e-mail messages are safe, they are advised not to open them.

Administrators may consider configuring Internet Explorer to prompt users before running Active Scripting or ActiveX controls by setting the Internet and Local Intranet security zone settings to High.  Alternately, administrators could disable Active Scripting and ActiveX controls in these security zones.

Administrators may consider using the Microsoft Baseline Security Analyzer (MBSA) scan tool to identify common security misconfigurations and missing security updates on system endpoints.

Administrators are advised to monitor critical systems.

 
Patches/Software
Microsoft customers can obtain updates directly by using the links in the security bulletin. These updates are also distributed by Windows automatic update features and available on the Windows Update website. Microsoft Windows Server Update Services (WSUS), Systems Management Server, and System Center Configuration Manager can assist administrators in deploying software updates.
