CVE-2006-0633: Invisionpower Invision Power Board

Medium severity, CVSS 6.4. EPSS: 1.2% chance of exploitation in the next 30 days.

The make_password function in ipsclass.php in Invision Power Board (IPB) 2.1.4 uses random data generated from partially predictable seeds to create the authentication code that is sent by e-mail to a user with a lost password, which might make it easier for remote attackers to guess the code and change the password for an IPB account, possibly involving millions of requests.
