CVE-2008-1930 Information

Description

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.
