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 IBM WebSphere Application Server running on the remote host is version 7.0 prior to 7.0.0.39, 8.0 prior to 8.0.0.11, or 8.5 prior to 8.5.5.6. It is, therefore, potentially affected by multiple vulnerabilities : - A security feature bypass vulnerability, known as FREAK (Factoring attack on RSA-EXPORT Keys), exists in the IBM Global Security Kit (GSKit) due to the support of weak EXPORT_RSA cipher suites with keys less than or equal to 512 bits. A man-in-the-middle attacker may be able to downgrade the SSL/TLS connection to use EXPORT_RSA cipher suites which can be factored in a short amount of time, allowing the attacker to intercept and decrypt the traffic. (CVE-2015-0138) - An information disclosure vulnerability exists due to a flaw in the Bleichenbacher countermeasure implementation in Apache WSS4J. A remote attacker can exploit this, via a crafted message, to determine where an encryption failure to place, allowing the attacker to gain access to the plaintext symmetric key. (CVE-2015-0226) - An XML External Entity (XXE) vulnerability exists due to an incorrectly configured XML parser that accepts XML external entities from an untrusted source. A remote attacker can exploit this, via specially crafted XML data, to gain access to arbitrary files. (CVE-2015-0250) - A privilege escalation vulnerability exists due to a flaw that occurs in

  - An XML External Entity (XXE) vulnerability exists due to

    external entities from an untrusted source. A remote
    attacker can exploit this, via specially crafted XML
    data, to gain access to arbitrary files. (CVE-2015-0250)

  - A privilege escalation vulnerability exists due to a
    flaw that occurs in 'full' profile and 'liberty' profile
    when using an OAuth grant password. A remote attacker
    can exploit this to gain elevated privileges.
    (CVE-2015-1885)

  - A privilege escalation vulnerability exists due to
    incorrect settings in the serveServletsbyClassname
    functionality. A remote attacker can exploit this to
    gain elevated privileges. (CVE-2015-1927)

  - An information disclosure vulnerability exists that
    allows an unauthenticated, remote attacker to identify
    the proxy server software by reading the HTTP 'Via'
    header. (CVE-2015-1932)

  - An unspecified flaw exists in the administrative console
    that allows a remote attacker, via the 'JSESSIONID'
    parameter, to hijack a user's session. (CVE-2015-1936)

  - A privilege escalation vulnerability exists due to an
    unspecified flaw that occurs when handling user roles.
    A local attacker can exploit this to gain elevated
    privileges. (CVE-2015-1946)
  
  - A security feature bypass vulnerability exists, known as
    Bar Mitzvah, due to improper combination of state data
    with key data by the RC4 cipher algorithm during the
    initialization phase. A man-in-the-middle attacker can
    exploit this, via a brute-force attack using LSB values,
