The wp_validate_auth_cookie function in wp-includes/pluggable.php in WordPress before 3.7.2 and 3.8.x before 3.8.2 does not properly determine the validity of authentication cookies, which makes it easier for remote attackers to obtain access via a forged cookie.

Multiple vulnerabilities has been discovered and corrected in wordpress :

WordPress before 3.7.2 and 3.8.x before 3.8.2 allows remote authenticated users to publish posts by leveraging the Contributor role, related to wp-admin/includes/post.php and wp-admin/includes/class-wp-posts-list-table.php (CVE-2014-0165).

The wp_validate_auth_cookie function in wp-includes/pluggable.php in WordPress before 3.7.2 and 3.8.x before 3.8.2 does not properly determine the validity of authentication cookies, which makes it easier for remote attackers to obtain access via a forged cookie (CVE-2014-0166).

The updated packages have been patched to correct these issues.

Several vulnerabilities were discovered in Wordpress, a web blogging tool. The Common Vulnerabilities and Exposures project identifies the following problems :

  - CVE-2014-0165     A user with a contributor role, using a specially     crafted request, can publish posts, which is reserved     for users of the next-higher role.

  - CVE-2014-0166     Jon Cave of the WordPress security team discovered that     the wp_validate_auth_cookie function in     wp-includes/pluggable.php does not properly determine     the validity of authentication cookies, allowing a     remote attacker to obtain access via a forged cookie.

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

  - A flaw exists within the application that could allow a     remote attacker with the contributor role to publish     posts. (CVE-2014-0165)

  - A authentication bypass flaw exists with the     'wp_validate_auth_cookie' function within the     'wp-includes/pluggable.php' script. This could allow a     remote attacker to bypass authentication using a forged     authentication cookie. (CVE-2014-0166)

  - A SQL injection flaw exists that could allow a remote     attacker who is a trusted user to manipulate or inject     SQL queries to the backend database, manipulating or     disclosing arbitrary data.

  - A cross-domain scripting flaw exists through Plupload.
    This could allow a remote attacker to execute arbitrary     code, with a specially crafted request, within the trust     relationship between the server and browser.

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