Multiple SQL injection vulnerabilities in Invision Power Board (IPB) 1.x and 2.x allow remote attackers to execute arbitrary SQL commands via the (1) idcat and (2) code parameters in a ketqua action in index.php; the id parameter in a (3) Attach and (4) ref action in index.php; the CODE parameter in a (5) Profile, (6) Login, and (7) Help action in index.php; and the (8) member_id parameter in coins_list.php.
