CVE-2013-4340

wp-admin/includes/post.php en WordPress anteriores a 3.6.1 permite a usuarios remotos autentificados falsear la autoría de una entrada aprovechando el rol Author y utilizando un parámetro user_ID modificado.

Updated wordpress and php-phpmailer packages fix security vulnerabilities. wp-includes/functions.php in WordPress before 3.6.1 does not properly determine whether data has been serialized, which allows remote attackers to execute arbitrary code by triggering erroneous PHP unserialize operations. WordPress before 3.6.1 does not properly validate URLs before use in an HTTP redirect, which allows remote attackers to bypass intended redirection restrictions via a crafted string. wp-admin/includes/post.php in WordPress before 3.6.1 allows remote authenticated users to spoof the authorship of a post by leveraging the Author role and providing a modified user_ID parameter. The get_allowed_mime_types function in wp-includes/functions.php in WordPress before 3.6.1 does not require the unfiltered_html capability for uploads of.htm and.html files, which might make it easier for remote authenticated users to conduct cross-site scripting attacks via a crafted file. The default configuration of WordPress before 3.6.1 does not prevent uploads of.swf and.exe files, which might make it easier for remote authenticated users to conduct cross-site scripting attacks via a crafted file, related to the get_allowed_mime_types function in wp-includes/functions.php. Additionally, php-phpmailer has been updated to a newer version required by the updated wordpress.
