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.

  - Escape sequences are not properly sanitized when passed
    to the 'Sanitizer::checkCss' class, which allows a
    remote attacker to conduct cross-site scripting attacks.
    (CVE-2013-6451)

  - An input validation error exists in the
    'XmlTypeCheck.php' script in uploaded SVG files that
    contain external style sheets, which allows a remote
    attacker to conduct cross-site scripting attacks.
    (CVE-2013-6452)

  - Input validation by the checkSvgScriptCallback()
    function is bypassed in the 'UploadBase.php' script
    when an SVG file with invalid XML is uploaded. This
    can result in malicious code execution. (CVE-2013-6453)

  - An input validation error exists in the 'Sanitizer.php'
    script when input is submitted to the '-o-link'
    attribute, which allows cross-site scripting attacks in
    Opera 12. (CVE-2013-6454)

  - An information disclosure vulnerability exists in the
    log API, Enhanced Recent Changes feature, and users'
    watchlists that allows deleted log entries to be viewed.
    (CVE-2013-6472)

Additionally, the following extensions contain vulnerabilities but
are not enabled or installed by default (unless otherwise noted) :

  - The TimedMediaHandler extension is affected by a
    cross-site scripting vulnerability due to the lack of
    input validation of the 'data-videopayload' attribute
    in the 'mw.PopUpThumbVideo.js' script. (CVE-2013-4574)

  - The Scribuntu extension is affected by a NULL pointer
    dereference and buffer overflow flaw in the
    implementation of the 'luasandbox' PHP extension that
    can lead to a denial of service or arbitrary code
    execution. (CVE-2013-4570, CVE-2013-4571)

  - The CentralAuth extension is affected by an information
    disclosure vulnerability due to the insertion of a
    username into the page's DOM. (CVE-2013-6455)

  - The Semantic Forms extension is affected by a cross-site
    request forgery (XSRF) vulnerability due to the lack of
    token validation in the 'Special:CreateCategory' page.
    (CVE-2014-3454)

"Updated mediawiki packages fix multiple vulnerabilities :

MediaWiki user Michael M reported that the fix for CVE-2013-4568
allowed insertion of escaped CSS values which could pass the CSS
validation checks, resulting in XSS (CVE-2013-6451).

Chris from RationalWiki reported that SVG files could be uploaded that
include external stylesheets, which could lead to XSS when an XSL was
used to include JavaScript (CVE-2013-6452).

During internal review, it was discovered that MediaWiki's SVG
sanitization could be bypassed when the XML was considered invalid
(CVE-2013-6453).

During internal review, it was discovered that MediaWiki displayed
some information about deleted pages in the log API, enhanced
RecentChanges, and user watchlists (CVE-2013-6472).

Netanel Rubin from Check Point discovered a remote code execution
vulnerability in MediaWiki's thumbnail generation for DjVu files.
Internal review also discovered similar logic in the PdfHandler
extension, which could be exploited in a similar way (CVE-2014-1610).

MediaWiki before 1.22.3 does not block unsafe namespaces, such as a
W3C XHTML namespace, in uploaded SVG files. Some client software may
use these namespaces in a way that results in XSS. This was fixed by
disallowing uploading SVG files using non-whitelisted namespaces
(CVE-2014-2242).

MediaWiki before 1.22.3 performs token comparison that may be
vulnerable to timing attacks. This was fixed by making token
comparison use constant time (CVE-2014-2243).

MediaWiki before 1.22.3 could allow an attacker to perform XSS
attacks, due to flaw with link handling in api.php. This was fixed
such that it won't find links in the middle of api.php links
(CVE-2014-2244).

MediaWiki has been updated to version 1.22.3, which fixes these
issues, as well as several others.

Also, the mediawiki-ldapauthentication and mediawiki-math extensions
have been updated to newer versions that are compatible with MediaWiki
1.22.

Additionally, the mediawiki-graphviz extension has been obsoleted, due
to the fact that it is unmaintained upstream and is vulnerable to
cross-site scripting attacks.

Note: if you were using the instances feature in these packages to
support multiple wiki instances, this feature has now been removed.
You will need to maintain separate wiki instances manually."

"The remote Debian host is missing a security update. It is, therefore,
affected by multiple vulnerabilities in MediaWiki :

  - A cross-site scripting (XSS) vulnerability exists due to
    a failure to validate input before returning it to the
    user. An unauthenticated, remote attacker can exploit
    this, via specially crafted SVG files, to execute
    arbitrary script code in the user's browser session.
    (CVE-2013-2031)

  - A flaw exists in the password blocking mechanism due to
    two different tools being used to block password change
    requests, these being Special:PasswordReset and
    Special:ChangePassword, either of which may be bypassed
    by the method the other prevents. A remote attacker can
    exploit this issue to change passwords. (CVE-2013-2032)

  - Multiple flaws exist in Sanitizer::checkCss due to the
    improper sanitization of user-supplied input. An
    unauthenticated, remote attacker can exploit these to
    bypass the blacklist. (CVE-2013-4567, CVE-2013-4568)

  - A flaw exists due to multiple users being granted the
    same session ID within HTTP headers. A remote attacker
    can exploit this to authenticate as another random
    user. (CVE-2013-4572)

  - A cross-site scripting (XSS) vulnerability exists in the
    /includes/libs/XmlTypeCheck.php script due to improper
    validation of user-supplied input. An unauthenticated,
    remote attacker can exploit this, via a specially
    crafted XSL file, to execute arbitrary script code in
    the user's browser session. (CVE-2013-6452)

  - A flaw exists in the /includes/upload/UploadBase.php
    script due to a failure to apply SVG sanitization when
    XML files are read as invalid. An unauthenticated,
    remote attacker can exploit this to upload non-sanitized
    XML files, resulting in an unspecified impact.
    (CVE-2013-6453)

  - A stored cross-site (XSS) scripting vulnerability exists
    in the /includes/Sanitizer.php script due to a failure
    to properly validate the '-o-link' attribute before
    returning it to users. An unauthenticated, remote
    attacker can exploit this, via a specially crafted
    request, to execute arbitrary script code in the user's
    browser session. (CVE-2013-6454)

  - A flaw exists in the log API within the
    /includes/api/ApiQueryLogEvents.php script that allows
    an unauthenticated, remote attacker to disclose
    potentially sensitive information regarding deleted
    pages. (CVE-2013-6472)

  - Multiple flaws exist in the PdfHandler_body.php,
    DjVu.php, Bitmap.php, and ImageHandler.php scripts when
    DjVu or PDF file upload support is enabled due to
    improper sanitization of user-supplied input. An
    authenticated, remote attacker can exploit these, via
    the use of shell metacharacters, to execute execute
    arbitrary shell commands. (CVE-2014-1610)

  - A cross-site request forgery (XSRF) vulnerability exists
    in the includes/specials/SpecialChangePassword.php
    script due to a failure to properly handle a correctly
    authenticated but unintended login attempt. An
    unauthenticated, remote attacker, by convincing a user
    to follow a specially crafted link, can exploit this to
    reset the user's password. (CVE-2014-2665)");
