WordPress < 3.3.3 / 3.4.0 Multiple Vulnerabilities

medium Nessus Plugin ID 72984

Synopsis

The remote web server contains a PHP application that is affected by multiple vulnerabilities.

Description

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

- A cross-site scripting flaw exists in the 'edit-tags.php' script where it does not validate the 'slug' parameter upon submission. This could allow a remote attacker to create a specially crafted request that would execute arbitrary script code in a user's browser session within the trust relationship between the browser and server. (CVE-2012-6633)

- A flaw exists in the 'wp-admin/media-upload.php' script where input for the 'post_id' parameter is not properly sanitized. This could allow a remote attacker to access potentially sensitive information or bypass media-attachment restrictions. (CVE-2012-6634)

- A flaw exists in the 'wp-admin/includes/class-wp-posts-list-table.php' script where it fails to restrict access to the excerpt-view. This could allow a remote attacker to access potentially sensitive information when viewing a draft. (CVE-2012-6635)

- Some hardening was applied to prevent unfiltered HTML in comments. This could potentially allow clickjacking.

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

Solution

Upgrade to WordPress 3.3.3 / 3.4.0 or later.
