CVE-2013-2203

WordPress anterior a v3.5.2, cuando el directorio de archivos prohíbe el acceso de escritura, permite a atacantes remotos obtener información sensible a través de una petición de subida valida, lo que revela la ruta absoluta en un mensaje de error XMLHttpRequest.

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.
