CVE-2010-4626 Information

Description

The my_rand function in functions.php in MyBB (aka MyBulletinBoard) before 1.4.12 does not properly use the PHP mt_rand 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.
