VI. ANALYSIS
in server_privileges.php
line 27:
if ( isset( $dbname ) ) {
    //if ( preg_match( '/\\\\(?:_|%)/i', $dbname ) ) {
    if ( preg_match( '/(?<!\\\\)(?:_|%)/i', $dbname ) ) {
        $dbname_is_wildcard = true;
    } else {
        $dbname_is_wildcard = false;
    }
}
parameter $dbname is not validate properly.

line 1197:
if (isset($viewing_mode) && $viewing_mode == 'db') {
     $db = $checkprivs;
     $url_query .= '&amp;goto=db_operations.php';

     // Gets the database structure
     $sub_part = '_structure';
     require('./db_details_db_info.php');
     echo "\n";
} else {
    require('./server_links.inc.php');
}

line 1241: 
if ( empty( $adduser ) && empty( $checkprivs ) ) {

parameter $checkprivs not validate properly.
