Description

According to its self-reported version number, the instance of MediaWiki running on the remote host is affected by the following vulnerabilities :

  • A cross-site scripting (XSS) vulnerability exists in the includes/upload/UploadBase.php script due to improper validation of user-supplied input during the uploading of an SVG namespace. This allows a remote attacker to create a specially crafted request to execute arbitrary script code in a user

"According to its self-reported version number, the instance of
MediaWiki running on the remote host is affected by the following
vulnerabilities :

  - A cross-site scripting (XSS) vulnerability exists in the
    includes/upload/UploadBase.php script due to improper
    validation of user-supplied input during the uploading
    of an SVG namespace. This allows a remote attacker to
    create a specially crafted request to execute arbitrary
    script code in a user's browser session within the trust
    relationship between the browser and server.
    (CVE-2014-2242)

  - A flaw exists in the includes/User.php script in the
    theloadFromSession() function where the validation of
    user tokens is terminated upon encountering the first
    incorrect character. This allows a remote attacker to
    gain access to session tokens using a brute force timing
    attack. (CVE-2014-2243)

  - A cross-site scripting (XSS) vulnerability exists in the
    includes/api/ApiFormatBase.php script in the
    formatHTML() function due to improper validation of
    user-supplied input when handling links appended to
    api.php. This allows a context-dependent attacker to
    create a specially crafted request to execute arbitrary
    code in a user's browser session within the trust
    relationship between the browser and server.
    (CVE-2014-2244)

Note that Nessus has not tested for these issues but has instead
relied only on the application's self-reported version number.");
