Version Summary:Microsoft Office Access contains a vulnerability that could allow an unauthenticated, remote attacker to execute arbitrary code on a targeted system. Updates are available.
 
 
Description
Microsoft Office Access contains a vulnerability that could allow an unauthenticated, remote attacker to execute arbitrary code on a targeted system.

The vulnerability is due to unsafe memory operations performed when opening Microsoft Office Access documents. An unauthenticated, remote attacker could exploit this vulnerability by convincing a targeted user to open a malicious document. If successful, the attacker could execute arbitrary code on the system with the privileges of the user.

Microsoft has confirmed the vulnerability in a security bulletin and released software updates.
 
Warning Indicators
The following versions of Microsoft Office Access are affected:
  • Microsoft Access 2007 SP3 and prior
  • Microsoft Access 2010 SP2 and prior 32-bit and 64-bit editions
  • Microsoft Access 2013 32-bit and 64-bit editions
 
IntelliShield Analysis
To exploit the vulnerability, the attacker may provide a file to the user and persuade the user to open or execute the file by using misleading language or instructions.

The Cisco Applied Intelligence team has created an Applied Mitigation Bulletin to address vulnerabilities that Microsoft disclosed in the September 2013 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 September 2013
 
Vendor Announcements
Microsoft has released a security bulletin at the following link: MS13-074
 
Impact
An unauthenticated, remote attacker could exploit this vulnerability to execute arbitrary code on a targeted system with the privileges of a targeted user. If the user holds elevated privileges, the attacker could completely compromise the system.
 
Technical Information
The vulnerability is due to improper memory operations performed when handling Microsoft Office Access documents.

An unauthenticated, remote attacker could exploit the vulnerability by convincing a targeted user to open a malicious document on a targeted system. When processing the document, Microsoft Office Access may perform invalid memory operations that could result in memory corruption. The attacker could use the memory corruption 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 email messages from suspicious or unrecognized sources. If users cannot verify that links or attachments included in email messages are safe, they are advised not to open them.

Users may consider applying the Microsoft Office Isolated Conversion Environment (MOICE) to safely open Word, Excel, and PowerPoint files from suspicious or unrecognized sources on systems that are running Microsoft Office 2003 or Office 2007.

Administrators may consider using the Microsoft Baseline Security Analyzer (MBSA) scan tool to identify common security misconfigurations and missing security updates on system endpoints.
 
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 Microsoft Update service. Microsoft Windows Server Update Services (WSUS), Systems Management Server, and System Center Configuration Manager can assist administrators in deploying software updates.
