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.

"The remote host is running a version of EMC Documentum Content Server
that is affected by multiple vulnerabilities :

  - An error exists in the 'ssl3_read_bytes' function
    that permits data to be injected into other sessions
    or allows denial of service attacks. Note that this
    issue is exploitable only if SSL_MODE_RELEASE_BUFFERS
    is enabled. (CVE-2010-5298)

  - An error exists related to the implementation of the
    Elliptic Curve Digital Signature Algorithm (ECDSA) that
    could allow nonce disclosure via the 'FLUSH+RELOAD'
    cache side-channel attack. (CVE-2014-0076)

  - A buffer overflow error exists related to invalid DTLS
    fragment handling that permits the execution of
    arbitrary code or allows denial of service attacks.
    Note that this issue only affects OpenSSL when used
    as a DTLS client or server. (CVE-2014-0195)

  - An error exists in the 'do_ssl3_write' function that
    permits a NULL pointer to be dereferenced, which could
    allow denial of service attacks. Note that this issue
    is exploitable only if SSL_MODE_RELEASE_BUFFERS is
    enabled. (CVE-2014-0198)

  - An error exists related to DTLS handshake handling that
    could allow denial of service attacks. Note that this
    issue only affects OpenSSL when used as a DTLS client.
    (CVE-2014-0221)

  - An error exists in the processing of ChangeCipherSpec
    messages that allows the usage of weak keying material.
    This permits simplified man-in-the-middle attacks to be
    done. (CVE-2014-0224)

  - A remote code execution vulnerability exists due to
    improper authorization checks. A remote, authenticated
    attacker can exploit this vulnerability to execute
    arbitrary code. (CVE-2014-4618)

  - An information disclosure vulnerability exists due to a
    flaw in the Documentum Query Language (DQL) engine. A
    remote, authenticated attacker can exploit this
    vulnerability to conduct DQL injection attacks and
    read arbitrary data from the database. Note that this
    only affects Content Server installations running on
    Oracle Database. (CVE-2014-2520)

  - An error exists in the 'dtls1_get_message_fragment'
    function related to anonymous ECDH cipher suites. This
    could allow denial of service attacks. Note that this
    issue only affects OpenSSL TLS clients. (CVE-2014-3470)

  - An information disclosure vulnerability exists due to
    improper authorization checks on certain RPC commands.
    A remote, authenticated attacker can exploit this
    vulnerability to retrieve meta-data of unauthorized
    system objects. (CVE-2014-2521)");
