sql injection in phpbb

[jocanor jocanor <jocanor2002 () hotmail com>]

I found a vulnerability en phpbb 2.0.5 and prior, is probably also affect 2.0.6

this bug don't affect to version 2.0.7 

phpbb have a list of registereds users, when you click on a memebr of this list, you are requesting data to the 
database 

for example:

http://www.example.com/forum/profile.php?mode=viewprofile&u=2

this url show the information to the user with the uid = 2, the uid is a number assigned to users in phpbb.

but it isn't secure, because if you use this url, you can inject sql comands...

exploit:

http://www.example.com/profile.php?mode=viewprofile&u='[sqlcode]

where [sql code] represents the code may be injected.
