Summary

The Client/Server Run-time Subsystem (CSRSS) in Microsoft Windows Vista SP2, Windows Server 2008 SP2 and R2 SP1, Windows 7 SP1, Windows 8, Windows 8.1, Windows Server 2012 Gold and R2, and Windows RT Gold and 8.1 allows local users to obtain sensitive information via a crafted application that continues to execute during a subsequent user's login session, aka "Windows CSRSS 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 affected by multiple vulnerabilities : - Multiple remote code execution vulnerabilities exist due to the Windows Adobe Type Manager Library not properly handling specially crafted OpenType fonts. An attacker can exploit these, by using a crafted document or web page with embedded OpenType fonts, to execute arbitrary code in the context of the current user. (CVE-2015-2432, CVE-2015-2458, CVE-2015-2459, CVE-2015-2460, CVE-2015-2461, CVE-2015-2462) - Multiple remote code execution vulnerabilities exist in various components of Windows, .NET Framework, Office, Lync, and Silverlight due to a failure to properly handle TrueType fonts. An attacker can exploit these, by using a crafted document or web page with embedded TrueType fonts, to execute arbitrary code in the context of the current user. (CVE-2015-2435, CVE-2015-2455, CVE-2015-2456 CVE-2015-2463, CVE-2015-2464) - A remote code execution vulnerability exists due to Microsoft Office not properly handling Office Graphics Library (OGL) fonts. An attacker can exploit this, by using a crafted document or web page with embedded OGL fonts, to execute arbitrary code in the context of the user. (CVE-2015-2431) - A security feature bypass vulnerability exists due to a failure by the Windows kernel to properly initialize a memory address. An attacker, using a specially crafted application, can exploit this issue to bypass Kernel Address Space Layout Randomization (KASLR) and retrieve the base address of the kernel driver. (CVE-2015-2433) - An elevation of privilege vulnerability exists due to a flaw in the Windows Client/Server Run-time Subsystem (CSRSS) when terminating a process when a user logs off. An attacker can exploit this vulnerability to run code that monitors the actions of users who log on to the system, allowing the disclosure of sensitive information which could be used to elevate privileges or execute code. (CVE-2015-2453) - A security feature bypass vulnerability exists due to the Windows kernel-mode driver not properly validating and enforcing impersonation levels. An attacker can exploit this to gain elevated privileges on a targeted system. (CVE-2015-2454) - A security feature bypass vulnerability exists due to the Windows shell not properly validating and enforcing impersonation levels. An attacker can exploit this to bypass impersonation-level security and gain elevated privileges on a targeted system. (CVE-2015-2465)
