Microsoft Windows CVE-2017-11835 Information Disclosure Vulnerability

Risk:
Medium
Date Discovered:
November 14, 2017
Description:
Microsoft Windows is prone to an information-disclosure vulnerability. Attackers can exploit this issue to obtain sensitive information that may aid in launching further attacks.
Technologies Affected
  • Microsoft Windows 7 for 32-bit Systems SP1
  • Microsoft Windows 7 for x64-based Systems SP1
  • Microsoft Windows Server 2008 R2 for Itanium-based Systems SP1
  • Microsoft Windows Server 2008 R2 for x64-based Systems SP1
  • Microsoft Windows Server 2008 for 32-bit Systems SP2
  • Microsoft Windows Server 2008 for Itanium-based Systems SP2
  • Microsoft Windows Server 2008 for x64-based Systems SP2
Recommendations
  • Block external access at the network boundary, unless external parties require service.
    Filter access to the affected computer at the network boundary if global access isn't needed. Restricting access to only trusted computers and networks might greatly reduce the likelihood of a successful exploit.
  • Deploy network intrusion detection systems to monitor network traffic for malicious activity.
    Deploy NIDS to monitor network traffic for signs of anomalous or suspicious activity such as unexplained incoming and outgoing traffic. This may indicate exploit attempts or activity that results from successful exploits.
  • Do not follow links provided by unknown or untrusted sources.
    Web users should be cautious about following links to sites that are provided by unfamiliar or suspicious sources. Filtering HTML from emails may help remove a possible vector for transmitting malicious links to users.
Updates are available. Please see the references or vendor advisory for more information.
