Vulnerable Configurations
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.

NASL family Windows : Microsoft Bulletins NASL id SMB_NT_MS15-079.NASL description The version of Internet Explorer installed on the remote host is missing Cumulative Security Update 3082442. It is, therefore, affected by multiple vulnerabilities, the majority of which are remote code execution vulnerabilities. An attacker can exploit these vulnerabilities by convincing a user to visit a specially crafted website. Note that the majority of the vulnerabilities addressed by Cumulative Security Update 3082442 are mitigated by the Enhanced Security Configuration (ESC) mode which is enabled by default on Windows Server 2003, 2008, 2008 R2, 2012, and 2012 R2. last seen 2020-06-01 modified 2020-06-02 plugin id 85333 published 2015-08-11 reporter This script is Copyright (C) 2015-2019 and is owned by Tenable, Inc. or an Affiliate thereof. source https://www.tenable.com/plugins/nessus/85333 title MS15-079: Cumulative Security Update for Internet Explorer (3082442) NASL family Windows : Microsoft Bulletins NASL id SMB_NT_MS15-088.NASL description The remote Windows host is affected by an information disclosure vulnerability when files at a medium integrity level become accessible to Internet Explorer running in Enhanced Protection Mode (EPM).

A remote attacker can exploit these vulnerabilities by convincing a user to open a specially crafted Office file, resulting in the execution of arbitrary code in the context of the current user. (CVE-2015-1642, CVE-2015-2467, CVE-2015-2468, CVE-2015-2469, CVE-2015-2477) - An information disclosure vulnerability exists when files at a medium integrity level become accessible to Internet Explorer running in Enhanced Protection Mode (EPM). An attacker can exploit this vulnerability by leveraging another vulnerability to execute code in IE with EPM, and then executing Excel, Notepad, PowerPoint, Visio, or Word using an unsafe command line parameter. (CVE-2015-2423) - A remote code execution vulnerability exists due a failure to properly validate templates. A remote attacker can exploit this vulnerability by convincing a user to open a specially crafted template file, resulting in the execution of arbitrary code in the context of the current user. (CVE-2015-2466) - A remote code execution vulnerability exists when Office decreases an integer value beyond its intended minimum value. A remote attacker can exploit this vulnerability by convincing a user to open a specially crafted Office file, resulting in the execution of arbitrary code in the context of the current user.
