#Vulnerabilities:
Input Validation Holes Permit SQL Injection and Cross-Site Scripting
Attacks.
#SQL Injection#
A problem of sanitation in resend.asp, news_view.asp, could lead an attacker
to inject SQL code to manipulate and disclose information from the database.
The same problem is present in administration site in more scripts.
Examples:
http://[host]/resend.asp?ID=[SQL query]
http://[host]/news_view.asp?ID=[SQL query]
#Cross-Site Scripting#
Another problem of sanitation permits an attacker inject a XSS in the
register form (register.asp), this will be executed at the administration
site permitting the attacker to modify or delete data.
Also is possible a XSS attack in error.asp.
Example:
http://[host]/error.asp?err=";>[XSS]
Example to delete a user:
In the register form: "><iframe src=http://[host]/admin/user_del.asp?ID=[ID
to delete]>
