WordPress Core < 2.5.1 - Authentication Bypass

Authentication Bypass Using an Alternate Path or Channel
CVE CVE-2008-1930
CVSS High (8.1)
Publicly Published April 25, 2008
Last Updated January 22, 2024
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.
