Vulnerability Overview

WordPress before 2.6.2 does not properly handle MySQL warnings about insertion of username strings that exceed the maximum column width of the user_login column, and does not properly handle space characters when comparing usernames, which allows remote attackers to change an arbitrary user's password to a random value by registering a similar username and then requesting a password reset, related to a "SQL column truncation vulnerability." NOTE: the attacker can discover the random password by also exploiting CVE-2008-4107.

Technical Analysis

REMEDIATION: Update to version 2.6.2, or a newer patched version --- IDENTIFIER: CWE-197 (Numeric Truncation Error) Truncation errors occur when a primitive is cast to a primitive of a smaller size and data is lost in the conversion.
