medium Nessus Plugin ID 93470
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 is different from CVSS.

VPR Score: 6.7

Synopsis

The remote host is affected by multiple vulnerabilities.

Description

The remote Windows host is missing a security update. It is, therefore, affected by multiple vulnerabilities :

- Multiple elevation of privilege vulnerabilities exist due to improper handling of session objects. A local attacker can exploit these, via a specially crafted application, to hijack the session of another user.
(CVE-2016-3305, CVE-2016-3306)

- A flaw exists in the Windows Kernel API due to improper enforcement of permissions. A local attacker can exploit this, via a specially crafted application, to elevate privileges and thereby disclose potentially sensitive information. (CVE-2016-3371)

- An elevation of privilege vulnerability exists in the Windows Kernel API due to improper enforcement of permissions. A local attacker can exploit this, via a specially crafted application, to impersonate processes, interject cross-process communication, or interrupt system functionality. (CVE-2016-3372)

- A flaw exists in the Windows Kernel API due to improperly allowing access to sensitive registry information. A local attacker can exploit this, via a specially crafted application, to elevate privileges and thereby gain access to user account information.
(CVE-2016-3373)

Solution

Microsoft has released a set of patches for Windows Vista, 2008, 7, 2008 R2, 2012, 8.1, RT 8.1, 2012 R2, and 10.
