Microsoft Windows up to Server 2012 R2 Kernel information disclosure

CVSS Meta Temp Score
CVSS is a standardized scoring system to determine possibilities of attacks. The Temp Score considers temporal factors like disclosure, exploit and countermeasures. The unique Meta Score calculates the average score of different sources to provide a normalized scoring system.
Current Exploit Price (≈)
Our analysts are monitoring exploit markets and are in contact with vulnerability brokers. The range indicates the observed or calculated exploit price to be seen on exploit markets. A good indicator to understand the monetary effort required for and the popularity of an attack.
CTI Interest Score
Our Cyber Threat Intelligence team is monitoring different web sites, mailing lists, exploit markets and social media networks. The CTI Interest Score identifies the interest of attackers and the security community for this specific vulnerability in real-time. A high score indicates an elevated risk to be targeted for this vulnerability.

Detailsinfo

A vulnerability has been found in Microsoft Windows up to Server 2012 R2 (Operating System) and classified as problematic. Affected by this vulnerability is some unknown functionality of the component Kernel. The manipulation with an unknown input leads to a information disclosure vulnerability. The CWE definition for the vulnerability is CWE-200. The product exposes sensitive information to an actor that is not explicitly authorized to have access to that information. As an impact it is known to affect confidentiality.

The bug was discovered 06/13/2017. The weakness was presented 06/13/2017 by Mateusz Jurczyk with Google Project Zero as KB4022010 as confirmed security update guide (Website). The advisory is shared at portal.msrc.microsoft.com. This vulnerability is known as CVE-2017-8488 since 05/03/2017. An attack has to be approached locally. A single authentication is required for exploitation. Technical details are unknown but a public exploit is available. MITRE ATT&CK project uses the attack technique T1592 for this issue. The advisory points out:

An information disclosure vulnerability exists when the Windows kernel improperly initializes objects in memory. To exploit this vulnerability, an authenticated attacker could run a specially crafted application. An attacker who successfully exploited this vulnerability could obtain information to further compromise the user’s system. The update addresses the vulnerability by correcting how the Windows kernel initializes objects in memory.

A public exploit has been developed by Google Security Research in C++ and been published 2 weeks after the advisory. It is possible to download the exploit at exploit-db.com. It is declared as proof-of-concept. We expect the 0-day to have been worth approximately $5k-$25k. The vulnerability scanner Nessus provides a plugin with the ID 100761 (Windows 7 and Windows Server 2008 R2 June 2017 Security Updates), which helps to determine the existence of the flaw in a target environment. It is assigned to the family Windows : Microsoft Bulletins and running in the context l. The commercial vulnerability scanner Qualys is able to test this issue with plugin 91385 (Microsoft Windows Security Update June 2017).

Applying the patch KB4022010 is able to eliminate this problem. The bugfix is ready for download at catalog.update.microsoft.com. A possible mitigation has been published immediately after the disclosure of the vulnerability.

The vulnerability is also documented in the databases at Exploit-DB (42212), Tenable (100761) and SecurityFocus (BID 98864†). See VDB-102386, VDB-102396, VDB-102401 and VDB-102416 for similar entries. Several companies clearly confirm that VulDB is the primary source for best vulnerability data.
