Subject: 
A Vulnerability in Microsoft Video Control Could Allow For Remote Code Execution (MS16-131)
Overview: 

A vulnerability has been discovered in Microsoft Video Control, which could allow for remote code execution. Microsoft Video Control is a lightweight ActiveX control that gives Automation clients access to features of DirectShow. This vulnerability can be exploited by convincing a user to open a specially crafted document or visit a specially crafted webpage. Successful exploitation of this vulnerability could result in an attacker gaining the same privileges as the logged on user. Depending on the privileges associated with the user, an attacker could then install programs; view, change, or delete data; or create new accounts with full user rights. Users whose accounts are configured to have fewer user rights on the system could be less impacted than those who operate with administrative user rights.

Systems Affected: 
  • Microsoft Windows Vista, 7, 8.1, RT 8.1, 10

Description: 

A remote code execution vulnerability exists when Microsoft Video Control fails to properly handle objects in memory. This vulnerability could be exploited if a user opens a specially crafted file or application from either a webpage or an email message. The Preview Pane is also an attack vector for this vulnerability. (CVE-2016-7248). 

 

Successful exploitation of this vulnerability could result in an attacker gaining the same privileges as the logged on user. Depending on the privileges associated with the user, an attacker could then install programs; view, change, or delete data; or create new accounts with full user rights. Users whose accounts are configured to have fewer user rights on the system could be less impacted than those who operate with administrative user rights.

Actions: 
  • After appropriate testing, apply patches provided by Microsoft to vulnerable systems.
  • Run all software as a non-privileged user (one without administrative privileges) to diminish the effects of a successful attack.
  • Remind users not to visit websites or follow links provided by unknown or untrusted sources.
  • Inform and educate users regarding the threats posed by hypertext links contained in emails or attachments especially from untrusted sources.
  • Apply the Principle of Least Privilege to all systems and services.
