New! Vulnerability Priority Rating (VPR)

Tenable calculates a dynamic VPR for every vulnerability. VPR combines vulnerability information with threat intelligence and machine learning algorithms to predict which vulnerabilities are most likely to be exploited in attacks. Read more about what VPR is and how it's different from CVSS.

VPR Score: 3.6

Synopsis

The remote host is affected by a security bypass vulnerability.

Description

The remote Windows host is missing a security update. It is, therefore, affected by a security bypass vulnerability in the Secure Boot component due to improperly applying an affected policy. An attacker who has either administrative privileges or access to the host can exploit this issue, via installing a crafted policy, to disable code integrity checks, thus allowing test-signed executables and drivers to be loaded on the target host. Moreover, the attacker can exploit this issue to bypass the Secure Boot integrity validation for BitLocker and the device encryption security features.

Solution

Microsoft has released a set of patches for Windows 2012, 8.1, RT 8.1, 2012 R2, and 10
