Xtreme ASP Photo Gallery 2.0 - 'displaypic.asp?sortorder' SQL Injection

source: https://www.securityfocus.com/bid/21138/info

Xtreme ASP Photo Gallery is prone to multiple input-validation vulnerabilities, including cross-site scripting and SQL-injection issues and an HTML-injection issue because the application fails to properly sanitize user-supplied input. 

Successful exploits of these vulnerabilities could allow an attacker to compromise the application, access or modify data, steal cookie-based authentication credentials, or even exploit vulnerabilities in the underlying database implementation. Other attacks are also possible.
