Technical 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.

NVD vector: AV:N/AC:H/Au:N/C:P/I:P/A:P
