Synopsis

The remote host is affected by multiple elevation of privilege vulnerabilities.

Description

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

- An elevation of privilege vulnerability exists in the Web Proxy Auto Discovery (WPAD) protocol due to improper handling of the proxy discovery process. A remote attacker can exploit this, by responding to NetBIOS name requests for WPAD, to bypass security restrictions and gain elevated privileges. (CVE-2016-3213)

- An elevation of privilege vulnerability exists in the Web Proxy Auto Discovery (WPAD) protocol due to improper handling of certain proxy discovery scenarios. A remote attacker can exploit this to elevate privileges, resulting in the ability to disclose or control network traffic. (CVE-2016-3236)

- An elevation of privilege vulnerability exists in NetBIOS due to improper handling of responses. A remote attacker can exploit this, via specially crafted NetBIOS responses, to appear as a trusted network device, resulting in the ability to render untrusted content in a browser outside of Enhanced Protected Mode (EPM) or an application container. (CVE-2016-3299)

Solution

Microsoft has released a set of patches for Windows Vista, 2008, 7, 2008 R2, 8, 2012, 8.1, RT 8.1, 2012 R2, and 10.

Note that cumulative update 3160005 in MS16-063 must also be installed in order to fully resolve CVE-2016-3213.
