MS-ISAC CYBER SECURITY ADVISORY NUMBER:
2014-086

DATE(S) ISSUED:
10/14/2014

SUBJECT:
Vulnerability in OLE Could Allow Remote Code Execution (MS14-060)

OVERVIEW:

A vulnerability has been discovered in Microsoft Windows Object Linking and Embedding (OLE), which could allow an attacker to take complete control of an affected system. Microsoft OLE allows an application to link part of a document to another application of a different type for processing.

The vulnerability could allow remote code execution if a user opens a specially crafted file. Successful exploitation of this vulnerability could allow the attacker to could gain the same user rights as the current user. An attacker could then install programs; view, change, or delete data; or create new accounts with full user rights.

THREAT INTELLIGENCE
This vulnerability is being exploited via Sandworm, which is being used in a Russian cyber-espionage campaign. Currently, this campaign is targeting NATO, European Unions, Telecommunications and Energy Sectors, as well as U.S. academic organizations. These limited, targeted attacks are using Microsoft PowerPoint 2007 files.

SYSTEM AFFECTED:

  • Windows Vista
  • Windows 7
  • Windows Server 2008
  • Windows Server 2008 R2
  • Windows Server 2012
  • Windows Server 2012 R2
  • Windows 8
  • Windows 8.1
  • Windows RT
  • Windows RT 8.1

RISK:
Government:

  • Large and medium government entities: High
  • Small government entities: High

Businesses:

  • Large and medium business entities: High

Home users: High

TECHNICAL SUMMARY:
A vulnerability has been discovered in Microsoft Windows Object Linking and Embedding (OLE). The vulnerability can be exploited by opening a specially crafted Microsoft office file that contains OLE objects. In an email scenario, the user will need to open the file. In a web-based scenario, the user will need to visit a webpage that contains a specially crafted PowerPoint file using OLE objects.

Successful exploitation of this vulnerability could allow the attacker to could gain the same user rights as the current user. An attacker could then install programs; view, change, or delete data; or create new accounts with full user rights.

RECOMMENDATIONS:
We recommend the following actions be taken:

  • Apply appropriate patches provided by Microsoft to vulnerable systems immediately after appropriate testing.
  • Run all software as a non-privileged user (one without administrative privileges) to diminish the effects of a successful attack.
  • Remind users not to download, accept, or execute files from un-trusted or unknown sources.
  • Remind users not to visit un-trusted websites or follow links provided by unknown or un-trusted sources.
