Summary

Microsoft Word 2007, Office 2010 SP2, Word 2010 SP2, Word for Mac 2011, Excel for Mac 2011, Word Viewer, Office Compatibility Pack SP3, Word Automation Services on SharePoint Server 2013 SP1, and Office Web Apps 2010 SP2 allow remote attackers to obtain sensitive information from process memory or cause a denial of service (out-of-bounds read) via a crafted Office document, aka "Microsoft Office Information Disclosure 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 Microsoft Office application installed on the remote Windows host is missing a security update. It is, therefore, affected by multiple vulnerabilities : - Multiple remote code execution vulnerabilities exist due to improper handling of objects in memory. An unauthenticated, remote attacker can exploit these by convincing a user to visit a specially crafted website or open a specially crafted Office file, resulting in the execution of arbitrary code in the context of the current user. (CVE-2016-7213, CVE-2016-7228, CVE-2016-7229, CVE-2016-7230, CVE-2016-7231, CVE-2016-7232, CVE-2016-7234, CVE-2016-7235, CVE-2016-7236, CVE-2016-7245) - An information disclosure vulnerability exists due to an out-of-bounds read error caused by an uninitialized variable. An unauthenticated, remote attacker can exploit this by convincing a user to open a specially crafted Office file, resulting in the disclosure of memory contents. (CVE-2016-7233) - A denial of service vulnerability exists due to improper handling of objects in memory. An unauthenticated, remote attacker can exploit this by convincing a user to open a specially crafted file, resulting in a crash of the application. (CVE-2016-7244)

It is, therefore, affected by multiple vulnerabilities : - Multiple remote code execution vulnerabilities exist due to improper handling of objects in memory. An unauthenticated, remote attacker can exploit these by convincing a user to visit a specially crafted website or open a specially crafted Office file, resulting in the execution of arbitrary code in the context of the current user.
