WordPress — свободно распространяемая система управления содержимым сайта с открытым исходным кодом.

The cookie authentication method in WordPress 2.5 relies on a hash of a concatenated string containing USERNAME and EXPIRY_TIME, which allows remote attackers to forge cookies by registering a username that results in the same concatenated string, as demonstrated by registering usernames beginning with "admin" to obtain administrator privileges, aka a "cryptographic splicing" issue. NOTE: this vulnerability exists because of an incomplete fix for CVE-2007-6013.

Multiple cross-site scripting (XSS) vulnerabilities in WordPress 2.3.2 allow remote attackers to inject arbitrary web script or HTML via the (1) inviteemail parameter in an invite action to wp-admin/users.php and the (2) to parameter in a sent action to wp-admin/invites.php.

The XML-RPC implementation (xmlrpc.php) in WordPress before 2.3.3, when registration is enabled, allows remote attackers to edit posts of other blog users via unknown vectors.

Multiple directory traversal vulnerabilities in WordPress 2.0.11 and earlier allow remote attackers to read arbitrary files via a .. (dot dot) in (1) the page parameter to certain PHP scripts under wp-admin/ or (2) the import parameter to wp-admin/admin.php, as demonstrated by discovering the full path via a request for the \..\..\wp-config pathname; and allow remote attackers to modify arbitrary files via a .. (dot dot) in the file parameter to wp-admin/templates.php.

WordPress 2.0.11 and earlier allows remote attackers to obtain sensitive information via an empty value of the page parameter to certain PHP scripts under wp-admin/, which reveals the path in various error messages.

WordPress 2.2.x and 2.3.x allows remote attackers to obtain sensitive information via an invalid p parameter in an rss2 action to the default URI, which reveals the full path and the SQL database structure.

Multiple cross-site scripting (XSS) vulnerabilities in WordPress 2.0.9 and earlier allow remote attackers to inject arbitrary web script or HTML via the popuptitle parameter to (1) wp-admin/post.php or (2) wp-admin/page-new.php.

Directory traversal vulnerability in wp-db-backup.php in WordPress 2.0.3 and earlier allows remote attackers to read arbitrary files, delete arbitrary files, and cause a denial of service via a .. (dot dot) in the backup parameter in a wp-db-backup.php action to wp-admin/edit.php. NOTE: this might be the same as CVE-2006-5705.1.

Cross-site scripting (XSS) vulnerability in wp-db-backup.php in WordPress 2.0.11 and earlier, and possibly 2.1.x through 2.3.x, allows remote attackers to inject arbitrary web script or HTML via the backup parameter in a wp-db-backup.php action to wp-admin/edit.php.

SQL injection vulnerability in wp-includes/query.php in WordPress 2.3.1 and earlier allows remote attackers to execute arbitrary SQL commands via the s parameter, when DB_CHARSET is set to (1) Big5, (2) GBK, or possibly other character set encodings that support a "\" in a multibyte character.
