This exploit allowed CL pin numbers to be cracked via an AOL web site.
Once the pin number was cracked the people involved could call AOL and
have the password reset. Also, after entering the correct pin number the
billing information on the accounts could be changed.
Chris, the person who figured out how to do this, was at the Community
Leaders Headquarters (CLHQ) and found a link to the CL Registration Update
page. This could be accessed by going to keyword: CLHQ > Requests > CL
Registration Update. The web page that he was brought to was
http://www.people.web.aol.com/cls/update. On this page it asked for the
CL's screen name and pin number. After entering a screen name and a pin
number it would give you a message of "Your screen name and PIN Number do
not match," or "Your screen name is not listed as a registered Community
Leader screen name," or it would proceed to the update registration page.
Pin numbers are four digits long and consist of numbers. Now it was only a
matter of going through every pin number (0000 - 9999) until it brought
you to the next page. Chris aka Sickness had his friend Trez make a
program to do it automatically. With this program they cracked CL's pin
numbers. Then they could either change the billing information then call and
have the password reset or just call with the pin number and have the
password reset.
After AOL realized that this was happening they changed the password reset
requirements. People who called now had to not only supply the pin number
but the credit card information as well. AOL also closed the web site. A
few days later the CLHQ's page said, "The CL Update area in Keyword: CLHQ
(CLHQ > Requests > CL Registration Update) is temporarily unavailable.
Please continue to update your personal information via Keyword: Billing.
We'll let you know when the CL Update area in CLHQ is back online." With
this the exploit died.
