Multiple SQL injection vulnerabilities in Elvin 1.2.0 allow remote attackers to execute arbitrary SQL commands via the (1) inUser (aka Username) and (2) inPass (aka Password) parameters to (a) inc/login.ei, reachable through login.php; and the (3) id parameter to (b) show_bug.php and (c) show_activity.php.  NOTE: it was later reported that vector 3c also affects 1.2.2.
