{"id":"CVE-2008-1930","details":"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.","modified":"2026-04-10T03:39:53.445083Z","published":"2008-04-28T20:05:00Z","references":[{"type":"ADVISORY","url":"http://secunia.com/advisories/29965"},{"type":"ADVISORY","url":"http://www.cl.cam.ac.uk/users/sjm217/advisories/wordpress-cookie-integrity.txt"},{"type":"ADVISORY","url":"http://www.vupen.com/english/advisories/2008/1372/references"},{"type":"FIX","url":"http://wordpress.org/development/2008/04/wordpress-251/"},{"type":"FIX","url":"http://www.securityfocus.com/bid/28935"},{"type":"WEB","url":"http://www.securityfocus.com/archive/1/491356/100/0/threaded"},{"type":"WEB","url":"http://www.securitytracker.com/id?1019923"},{"type":"WEB","url":"https://exchange.xforce.ibmcloud.com/vulnerabilities/42027"}],"schema_version":"1.7.5"}
