Common Weakness Enumeration (CWE)

Common Attack Pattern Enumeration and Classification (CAPEC)

  • Cross Site Scripting through Log Files
    An attacker may leverage a system weakness where logs are susceptible to log injection to insert scripts into the system's logs. If these logs are later viewed by an administrator through a thin administrative interface and the log data is not properly HTML encoded before being written to the page, the attackers' scripts stored in the log will be executed in the administrative interface with potentially serious consequences. This attack pattern is really a combination of two other attack patterns: log injection and stored cross site scripting.
  • Embedding Scripts in Non-Script Elements
    This attack is a form of Cross-Site Scripting (XSS) where malicious scripts are embedded in elements that are not expected to host scripts such as image tags (<img>), comments in XML documents (< !-CDATA->), etc. These tags may not be subject to the same input validation, output validation, and other content filtering and checking routines, so this can create an opportunity for an attacker to tunnel through the application's elements and launch a XSS attack through other elements. As with all remote attacks, it is important to differentiate the ability to launch an attack (such as probing an internal network for unpatched servers) and the ability of the remote attacker to collect and interpret the output of said attack.
  • Embedding Scripts within Scripts
    An attack of this type exploits a programs' vulnerabilities that are brought on by allowing remote hosts to execute scripts. The attacker leverages this capability to execute scripts to execute his/her own script by embedding it within other scripts that the target software is likely to execute. The attacker must have the ability to inject script into script that is likely to be executed. If this is done, then the attacker can potentially launch a variety of probes and attacks against the web server's local environment, in many cases the so-called DMZ, back end resources the web server can communicate with, and other hosts. With the proliferation of intermediaries, such as Web App Firewalls, network devices, and even printers having JVMs and Web servers, there are many locales where an attacker can inject malicious scripts. Since this attack pattern defines scripts within scripts, there are likely privileges to execute said attack on the host. Of course, these attacks are not solely limited to the server side, client side scripts like Ajax and client side JavaScript can contain malicious scripts as well. In general all that is required is for there to be sufficient privileges to execute a script, but not protected against writing.
  • Cross-Site Scripting in Error Pages
    An attacker distributes a link (or possibly some other query structure) with a request to a third party web server that is malformed and also contains a block of exploit code in order to have the exploit become live code in the resulting error page. When the third party web server receives the crafted request and notes the error it then creates an error message that echoes the malformed message, including the exploit. Doing this converts the exploit portion of the message into to valid language elements that are executed by the viewing browser. When a victim executes the query provided by the attacker the infected error message error message is returned including the exploit code which then runs in the victim's browser. XSS can result in execution of code as well as data leakage (e.g. session cookies can be sent to the attacker). This type of attack is especially dangerous since the exploit appears to come from the third party web server, who the victim may trust and hence be more vulnerable to deception.
  • Cross-Site Scripting Using Alternate Syntax
    The attacker uses alternate forms of keywords or commands that result in the same action as the primary form but which may not be caught by filters. For example, many keywords are processed in a case insensitive manner. If the site's web filtering algorithm does not convert all tags into a consistent case before the comparison with forbidden keywords it is possible to bypass filters (e.g., incomplete black lists) by using an alternate case structure. For example, the "script" tag using the alternate forms of "Script" or "ScRiPt" may bypass filters where "script" is the only form tested. Other variants using different syntax representations are also possible as well as using pollution meta-characters or entities that are eventually ignored by the rendering engine. The attack can result in the execution of otherwise prohibited functionality.

  - 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)

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
