Microsoft Windows ADFS CVE-2017-0159 Security Bypass Vulnerability

Risk

Medium

Date Discovered

April 11, 2017

Description

Microsoft Windows is prone to a security-bypass vulnerability. An attacker can leverage this issue to bypass certain security restrictions and perform unauthorized actions.

Technologies Affected

  • Microsoft Windows 10 Version 1607 for x64-based Systems
  • Microsoft Windows 10 version 1703 for 32-bit Systems
  • Microsoft Windows Server 2012 R2
  • Microsoft Windows Server 2016

Recommendations

Block external access at the network boundary, unless external parties require service.

If global access isn't needed, filter access to the affected computer at the network boundary. Restricting access to only trusted computers and networks might greatly reduce the likelihood of successful exploits.

Run all software as a nonprivileged user with minimal access rights.

To reduce the impact of latent vulnerabilities, always run nonadministrative software as an unprivileged user with minimal access rights.

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. This includes but is not limited to unexplained incoming and outgoing traffic. This may indicate exploit attempts or activity that results from successful exploits.

Do not accept or execute files from untrusted or unknown sources.

Users should be cautious when installing and running application from untrusted sources.
Currently, we are not aware of any vendor-supplied patches. If you feel we are in error or if you are aware of more recent information, please mail us at: vuldb@securityfocus.com.
