Version Summary:Microsoft FrontPage contains a vulnerability that could allow an unauthenticated, remote attacker to access sensitive information. Updates are available.
 
 
Description
A vulnerability in Microsoft FrontPage could allow an unauthenticated, remote attacker to access sensitive information.

The vulnerability is due to improper parsing of a document type definition (DTD) in an XML file. An unauthenticated, remote attacker could exploit the vulnerability by convincing a user to visit a malicious website or open a crafted FrontPage document that is designed to submit malicious content to the affected software. Successful exploitation could allow the attacker to access sensitive information, such as the contents of a local file on an affected device, which could be used to conduct further attacks.

Microsoft confirmed the vulnerability in a security bulletin and released software updates.
 
Warning Indicators
Microsoft FrontPage 2003 is vulnerable.
 
IntelliShield Analysis
To exploit the vulnerability, the attacker may provide a link that directs a user to a malicious site or convince the user to open a crafted FrontPage document by using misleading language or instructions.

Microsoft has corrected the vulnerability by modifying the way the affected software handles DTD entities.

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: MS13-078
 
Impact

An unauthenticated, remote attacker could exploit the vulnerability by convincing a user to visit a malicious website or open a crafted FrontPage document that is designed to submit malicious content to the affected software. Successful exploitation could allow the attacker to access sensitive information, such as the contents of a local file on an affected device, which could be used to conduct further attacks.
 
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.

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 affected systems.
