CVE-2008-4106 Information

Description

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.
