[+] Team: Maher - CertCC.ir  
[+] Vendor Homepage: www.dleviet.com  
www.dle-news.com  
[+] Tested on: Windows 10 & Kali Linux  
[+] Versions: 13.0 and Before  
[+] Vulnerable Parameter: Post Method  
[+] Vulnerable File: /index.php?do=addnews & /addnews.html  
[+} Dork : inurl:/index.php?subaction=userinfo  
  
### Notes:  
  
An attacker can use XSS (in addnews fields section from datalife engine  
13.0 and Before)  
to send a malicious script to an unsuspecting Admins or users. The end  
admins or useras browser  
has no way to know that the script should not be trusted, and will execute  
the script. Because it thinks the script came from a trusted source, the  
malicious script can access any cookies, session tokens, or other sensitive  
information retained by the browser and used with that site. These scripts  
can even rewrite the content of the HTML page.  
  
### POC:  
  
[+] First, sign up through this path: http://localhost/index.php?do=register  
[+] Once logged in, Go to this page: http://localhost/index.php?do=addnews  
or  
http://localhost/addnews.html  
[+] For example, put this code in the fields: <img src="Image link">  
"><svg  
onload=alert('CertCC')>  
"><br>text  
[+] When the admin goes to validate your post, he will see your alert or  
executable code.  
[+] Therefore, the administrator and subsequent users are attacked by XSS.
