Fusetalk SQL injection submission.
Fusetalk SQL injection submission.
Fusetalk SQL injection submission.

I have found sql injection in FuseTalk 2.0 during a legitmate audit.
Resending because I got MIME errors to bugtraq@securityfocus.com. I 
have exchanged emails with rkeith@securityfocus.com who needed more 
information when I originally sent an email to vuldb@securityfocus.com 

Operating system and software installed.
-Microsoft SQL Server 2000 - 8.00.760 (Intel x86)
-Windows NT 5.0 SP4
-Fusetalk 2.0 Forums

How the vulnerability can be reproduced
-If a session is not prior established a error page disclosure will
reveal an input field where direct SQL queries can be used to disclose
confidential/sensitive information.
-FTVAR_SUBCAT= is the parameter where the injectiion occurs and its
value is sent as txForumID which allows 128 characters with no input
validation.  Direct SQL queries can occur to grab entire database

Protocol is HTTP
Port 80
Path may vary but was found on /community/forum/index.cfm
Query is FTVAR_SUBCAT=@@version&nocookies=y&subcatname
What impact the vulnerability has on the vulnerable system.
-Allows a remote attack to directly query the database and disclose
both sensitve/confidential information.

Any additional details that might help in the verification process
I had javascript off, because a pop-up does try to correct the input,
but through client-side validation.  Mozilla Firefox was used.

The error message when session is not prior established...
