The myrand function in functions.php in MyBB (aka MyBulletinBoard) before 1.4.12 does not properly use the PHP mtrand function, which makes it easier for remote attackers to obtain access to an arbitrary account by requesting a reset of the account's password, and then conducting a brute-force attack.
