###############################################
Vuln. discovered by : r0t
Date: 26 june 2006
vendor:http://zorum.phpoutsourcing.com/
affected versions:3.5 and prior
###############################################

Vuln. Description:

1.
Zorum Forum contains a flaw that allows a remote sql injection attacks.Input passed to the "offset","tid","fromid","sortby","fromfrommethod","fromfromlist" parameter in "index.php" isn't properly sanitised before being used in a SQL query.
This can be exploited to manipulate SQL queries by injecting arbitrary SQL code.

2.
Zorum Forum contains a flaw that allows a remote Cross-Site Scripting attacks.Input passed to the "frommethod","list","method" parameter in "index.php" and most parameters from SQL injection vuln. isn't properly sanitised before being returned to the user.
This can be exploited to execute arbitrary HTML and script code in a user's browser session in context of an affected site.


Additional info:
Some of those parameters by both vulnerabilities will give Full Path Disclosure and there will be many other parameters wich isnt properly sanitised.
And if it will be not enough you can aslo figure out something like sql injection form search engine module, just try to add in any possible field some "unsanitised" input and you will see.
