Vulnerability Overview

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.

Technical Analysis

REMEDIATION: Update to version 2.5.1, or a newer patched version --- IDENTIFIER: CWE-288 (Authentication Bypass Using an Alternate Path or Channel) The product requires authentication, but the product has an alternate path or channel that does not require authentication.
