"The version of WordPress installed on the remote host is affected by
multiple vulnerabilities :

  - The application is affected by a SQL injection
    vulnerability because it fails to properly sanitize
    user-supplied input passed via the 'tb_id' parameter
    to the 'wp-trackback.php' script before using it in
    database queries. This could lead to disclosure of
    sensitive information or attacks against the underlying
    database. (CVE-2005-1687)

  - The application contains an information disclosure flaw
    in which paths can be exposed in error messages after
    direct requests to files in '/wp-content/themes/',
    '/wp-includes', and '/wp-admin/'.  (CVE-2005-1688)

  - The application is affected by multiple cross-site
    scripting vulnerabilities. An attacker can pass
    arbitrary HTML and script code through the 's'
    parameter of the 'wp-admin/edit.php' script or the
    'p' parameter in the 'wp-admin/post.php' script, thereby
    facilitating cross-site scripting attacks. Note that
    these attacks will only be successful against
    administrators since the scripts themselves are limited
    to administrators.");
