Summary

The kernel-mode drivers in Microsoft Windows Vista SP2, Windows Server 2008 SP2 and R2 SP1, Windows 7 SP1, Windows 8.1, Windows Server 2012 Gold and R2, Windows RT 8.1, and Windows 10 Gold, 1511, and 1607 allow local users to gain privileges via a crafted application, aka "Win32k Elevation of Privilege Vulnerability." a different vulnerability than CVE-2016-3266, CVE-2016-7185, and CVE-2016-7211.

Common Weakness Enumeration (CWE)

Common Attack Pattern Enumeration and Classification (CAPEC)

  • Restful Privilege Elevation
    Rest uses standard HTTP (Get, Put, Delete) style permissions methods, but these are not necessarily correlated generally with back end programs. Strict interpretation of HTTP get methods means that these HTTP Get services should not be used to delete information on the server, but there is no access control mechanism to back up this logic. This means that unless the services are properly ACL'd and the application's service implementation are following these guidelines then an HTTP request can easily execute a delete or update on the server side. The attacker identifies a HTTP Get URL such as http://victimsite/updateOrder, which calls out to a program to update orders on a database or other resource. The URL is not idempotent so the request can be submitted multiple times by the attacker, additionally, the attacker may be able to exploit the URL published as a Get method that actually performs updates (instead of merely retrieving data). This may result in malicious or inadvertent altering of data on the server.

descriptionThe remote Windows host is missing a security update. It is, therefore, affected by multiple vulnerabilities : - Multiple elevation of privilege vulnerabilities exist in the Windows kernel-mode driver due to improper handling of objects in memory. A local attacker can exploit these, via a specially crafted application, to execute arbitrary code in kernel mode. (CVE-2016-3266, CVE-2016-3376, CVE-2016-7185, CVE-2016-7191) - An elevation of privilege vulnerability exists in Windows Transaction Manager due to improper handling of objects in memory.
