Descriptions

wp-includes/class-phpass.php in WordPress 3.5.1, when a password-protected post exists, allows remote attackers to cause a denial of service (CPU consumption) via a crafted value of a certain wp-postpass cookie.

wp-includes/class-phpass.php en WordPress v3.5.1, cuando un password protegido existe, permite a atacantes remotos causar una denegaciĆ³n de servicio (consumo de CPU) mediante una valor especialmente diseƱado para cierto cookie wp-postpass.

A denial of service flaw was found in the way Wordpress, a blog tool and publishing platform, performed hash computation when checking password for password protected blog posts. A remote attacker could provide a specially-crafted input that, when processed by the password checking mechanism of Wordpress would lead to excessive CPU consumption. Inadequate SSRF protection for HTTP requests where the user can provide a URL can allow for attacks against the intranet and other sites. This is a continuation of work related to which was specific to SSRF in pingback requests and was fixed in 3.5.1. Inadequate checking of a user's capabilities could allow them to publish posts when their user role should not allow for it; and to assign posts to other authors. Inadequate escaping allowed an administrator to trigger a cross-site scripting vulnerability through the uploading of media files and plugins. The processing of an oEmbed response is vulnerable to an XXE. If the uploads directory is not writable, error message data returned via XHR will include a full path to the directory. Content Spoofing in the MoxieCode MoxiePlayer project. Cross-domain XSS in SWFUpload.
