Multiple SQL injection vulnerabilities in ClanSphere 2009.0.3 and earlier allow remote attackers to execute arbitrary SQL commands via (1) the IP address to the cs_getip function in generate.php in the Captcha module, or (2) the s_email parameter to the cs_sql_select function in the MySQL database driver (mysql.php).
The product constructs all or part of an SQL command using externally-influenced input from an upstream component, but it does not neutralize or incorrectly neutralizes special elements that could modify the intended SQL command when it is sent to a downstream component. Without sufficient removal or quoting of SQL syntax in user-controllable inputs, the generated SQL query can cause those inputs to be interpreted as SQL instead of ordinary user data.
