"According to its version number, the installation of WordPress hosted
on the remote web server is affected by multiple vulnerabilities :

  - A SQL injection vulnerability exists in the
    'wp-includes/comment.php' script due to improper
    sanitization of user-supplied input to the 'Send
    Trackbacks' field. A remote attacker can exploit this to
    inject or manipulate SQL queries to manipulate or
    disclose arbitrary data. (CVE-2010-4257)

  - A cross-site scripting vulnerability exists in the
    request_filesystem_credentials() function in the
    'wp-admin/includes/file.php' script where input passed
    from an error message for an FTP or SSH connection
    attempt is not validated. This allows a
    context-dependent attacker to use a specially crafted
    request to execute arbitrary script code within the
    user's browser session. (CVE-2010-5294)

  - A cross-site scripting vulnerability exists in the
    'wp-admin/plugins.php' script due to improper validation
    of input supplied via a plugin's 'author' field. This
    allows a remote attacker to inject arbitrary script or
    HTML code in a user's browser session. (CVE-2010-5295)

  - A security bypass vulnerability exists in the
    'wp-includes/capabilities.php' script. When a multisite
    configuration is used, Super Admin privileges are not
    needed for the 'delete_users' capability. This allows an
    authenticated attacker to bypass access restrictions.
    (CVE-2010-5296)

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