Invision Power Board SQL Injection Vuln



Invision Power Board SQL Injection Vuln [ All Versions ]



Vendor  : Invision Power Services

URL     : http://www.invisionpower.com 

Version : All Versions Up To v2.0 Alpha 3

Risk    : SQL Injection Vulnerability





Description:

Invision Power Board (IPB) is a professional forum system that has been 

built from the ground up with speed and security in mind, taking advantage 

of object oriented code, highly-optimized SQL queries, and the fast PHP 

engine. A comprehensive administration control panel is included to help 

you keep your board running smoothly. Moderators will also enjoy the full 

range of options available to them via built-in tools and moderators control

panel. Members will appreciate the ability to subscribe to topics, send 

private messages, and perform a host of other options through the user 

control panel. It is used by millions of people over the world.





Problem:

Invision Power Board is vulnerable to an SQL Injection Vulnerability. All

versions up to 2.0 Alpha 3 seem to be affected. Below is an example URL

to test if you are vulnerable.





/index.php?showforum=1&prune_day=100&sort_by=Z-A&sort_key=[Problem_is_here]



If you are vulnerable (you should be) you will see an error message similar

to the one posted below. The only requirement is to know a valid forum number

and to have read access to that forum (must be able to view it).
