Summary

The kernel API 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 does not properly enforce permissions, which allows local users to obtain sensitive information via a crafted application, aka "Windows Kernel Elevation of Privilege Vulnerability."

Common Weakness Enumeration (CWE)

Common Attack Pattern Enumeration and Classification (CAPEC)

  • Subverting Environment Variable Values
    The attacker directly or indirectly modifies environment variables used by or controlling the target software. The attacker's goal is to cause the target software to deviate from its expected operation in a manner that benefits the attacker.
  • Footprinting
    An attacker engages in probing and exploration activity to identify constituents and properties of the target. Footprinting is a general term to describe a variety of information gathering techniques, often used by attackers in preparation for some attack. It consists of using tools to learn as much as possible about the composition, configuration, and security mechanisms of the targeted application, system or network. Information that might be collected during a footprinting effort could include open ports, applications and their versions, network topology, and similar information. While footprinting is not intended to be damaging (although certain activities, such as network scans, can sometimes cause disruptions to vulnerable applications inadvertently) it may often pave the way for more damaging attacks.
  • Exploiting Trust in Client (aka Make the Client Invisible)
    An attack of this type exploits a programs' vulnerabilities in client/server communication channel authentication and data integrity. It leverages the implicit trust a server places in the client, or more importantly, that which the server believes is the client. An attacker executes this type of attack by placing themselves in the communication channel between client and server such that communication directly to the server is possible where the server believes it is communicating only with a valid client. There are numerous variations of this type of attack.
  • Browser Fingerprinting
    An attacker carefully crafts small snippets of Java Script to efficiently detect the type of browser the potential victim is using. Many web-based attacks need prior knowledge of the web browser including the version of browser to ensure successful exploitation of a vulnerability. Having this knowledge allows an attacker to target the victim with attacks that specifically exploit known or zero day weaknesses in the type and version of the browser used by the victim. Automating this process via Java Script as a part of the same delivery system used to exploit the browser is considered more efficient as the attacker can supply a browser fingerprinting method and integrate it with exploit code, all contained in Java Script and in response to the same web page request by the browser.
  • Session Credential Falsification through Prediction
    This attack targets predictable session ID in order to gain privileges. The attacker can predict the session ID used during a transaction to perform spoofing and session hijacking.

descriptionThe 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.
