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.

| description | BUGTRAQ ID: 56439 CVE ID: CVE-2012-2531 Internet Information Services（IIS，互联网信息服务）是由微软公司提供的基于运行Microsoft Windows的互联网基本服务。 Microsoft IIS 7.5对操作日志使用了弱权限，没有正确限制对某些日志文件的访问，通过读取此文件，可允许本地用户获取已配置账户的用户名和密码。要利用此漏洞需要启用IIS的操作日志。 0 Microsoft IIS 7.x 临时解决方法： * 如果已经启用了IIS的"Operational"日志，则在分配给应用池自定义账户之前，请禁用 IIS配置的"Operational"，然后在关联了账户之后，重启"Operational"日志。 * 使用内置账户ID（例如LocalService, ApplicationPoolIdentity,等）而非应用池内 的自定义账户。 * 阻止非管理员账户访问EventViewer嵌入式管理单元。 厂商补丁： Microsoft --------- Microsoft已经为此发布了一个安全公告（MS12-073）以及相应补丁: MS12-073：Vulnerabilities in Microsoft Internet Information Services (IIS) Could Allow Information Disclosure (2733829) 链接：http://www.microsoft.com/technet/security/bulletin/MS12-073.asp |
