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 SharePoint Server installation on the remote host is missing security updates. It is, therefore, affected by multiple vulnerabilities : - A security feature bypass vulnerability exists when Microsoft Office does not validate URLs. An attacker could send a victim a specially crafted file, which could trick the victim into entering credentials. An attacker who successfully exploited this vulnerability could perform a phishing attack. The update addresses the vulnerability by ensuring Microsoft Office properly validates URLs. (CVE-2019-1442) - An information disclosure vulnerability exists in Microsoft SharePoint when an attacker uploads a specially crafted file to the SharePoint Server. An authenticated attacker who successfully exploited this vulnerability could potentially leverage SharePoint functionality to obtain SMB hashes. The security update addresses the vulnerability by correcting how SharePoint checks file content. (CVE-2019-1443) - An information disclosure vulnerability exists when Microsoft Excel improperly discloses the contents of its memory. An attacker who exploited the vulnerability could use the information to compromise the users computer or data. (CVE-2019-1446) - An information disclosure vulnerability exists in Microsoft SharePoint when an attacker sends a specially crafted API request to the SharePoint Server. An authenticated attacker who successfully exploited this vulnerability could potentially read arbitrary files on the server. The security update addresses the vulnerability by changing how affected APIs process requests. (CVE-2019-1491)

    descriptionThe Microsoft Office application installed on the remote macOS or Mac OS X host is missing a security update. It is, therefore, affected by multiple vulnerabilities: - An information disclosure vulnerability exists when Microsoft Excel improperly discloses the contents of its memory. An attacker who exploited the vulnerability could use the information to compromise the user’s computer or data. To exploit the vulnerability, an attacker could craft a special document file and then convince the user to open it. An attacker must know the memory address location where the object was created. (CVE-2019-1446) - A remote code execution vulnerability exists in Microsoft Excel software when the software fails to properly handle objects in memory. An attacker who successfully exploited the vulnerability could run arbitrary code in the context of the current user. If the current user is logged on with administrative user rights, an attacker could take control of the affected system. An attacker would have to convince users to click a link, typically by way of an enticement in an email or instant message, and then convince them to open the specially crafted file. (CVE-2019-1448) - A security feature bypass vulnerability exists in Microsoft Office software by not enforcing macro settings on an Excel document. The security feature bypass by itself does not allow arbitrary code execution. To successfully exploit the vulnerability, an attacker would have to embed a control in an Excel worksheet that specifies a macro should be run. To exploit the vulnerability, an attacker would have to convince a user to open a specially crafted file with an affected version of Microsoft Office software. (CVE-2019-1457)

"The Microsoft Office application installed on the remote macOS or Mac OS X host is missing a security update. It is,
therefore, affected by multiple vulnerabilities:

  - An information disclosure vulnerability exists when Microsoft Excel improperly discloses the contents of
    its memory. An attacker who exploited the vulnerability could use the information to compromise the user’s
    computer or data. To exploit the vulnerability, an attacker could craft a special document file and then
    convince the user to open it. An attacker must know the memory address location where the object was
    created. (CVE-2019-1446)

  - A remote code execution vulnerability exists in Microsoft Excel software when the software fails to
    properly handle objects in memory. An attacker who successfully exploited the vulnerability could run
    arbitrary code in the context of the current user. If the current user is logged on with administrative
    user rights, an attacker could take control of the affected system. An attacker would have to convince
    users to click a link, typically by way of an enticement in an email or instant message, and then convince
    them to open the specially crafted file. (CVE-2019-1448)

  - A security feature bypass vulnerability exists in Microsoft Office software by not enforcing macro
    settings on an Excel document. The security feature bypass by itself does not allow arbitrary code
    execution. To successfully exploit the vulnerability, an attacker would have to embed a control in an
    Excel worksheet that specifies a macro should be run. To exploit the vulnerability, an attacker would have
    to convince a user to open a specially crafted file with an affected version of Microsoft Office software.
