AlpHaNiX has reported some vulnerabilities in Click&Rank, which can be exploited by malicious people to conduct SQL injection attacks.
1) Input passed to the "userid" and "PassWord" parameters in admin_login.asp is not properly sanitised before being used in SQL queries. This can be exploited to manipulate SQL queries by injecting arbitrary SQL code.
Success exploitation of this vulnerability allows the attacker to bypass the authentication mechanism.
2) Input passed to the "id" parameter in hitcounter.asp, user_delete.asp, and user_update.asp is not properly sanitised before being used in SQL queries. This can be exploited to manipulate SQL queries by injecting arbitrary SQL code.
Solution: Edit the source code to ensure that input is properly sanitised.
