Technical Details & Description:  
================================  
A cross site request forgery web vulnerability has been discovered in  
the official DirectAdmin CP v1.50.0 control panel web-application.  
The vulnerability allows remote attacker to prepare client-side  
websites with malicious codes to execute internal application  
functions  
via non-expired user session credentials.  
  
DirectAdmin suffers from cross site request forgery web vulnerability  
that is located in the CMC_FILE_MANAGER module POST method request.  
Remote attackers are able to prepare malicious websites that can  
execute client-side application functions to add/edit via non-expired  
session.  
The attack vector of the issue is client-side and the request method  
to inject is POST. The attacker preapres a malicious website wiht a  
hidden  
POST method request to execute in the CMD_FILE_MANAGER the edit/add  
function with already defined perimeters.  
  
The security risk of the client-side web vulnerability is estimated as  
medium with a cvss (common vulnerability scoring system) count of 3.0.  
Exploitation of the non-persistent web vulnerability requires no  
privileged web application user account and low or medium user  
interaction.  
Successful exploitation of the vulnerability results in session  
hijacking, non-persistent phishing, non-persistent external redirects,  
non-persistent load of malicious script codes or non-persistent web  
module context manipulation.  
  
Request Method(s):  
[+] POST  
  
Vulnerable Module(s):  
[+] CMD_FILE_MANAGER  
  
Vulnerable Function(s):  
[+] Edit  
  
  
Proof of Concept (PoC):  
=======================  
The cross site request forgery vulnerability can be exploited by  
remote attackers without privileged application user account and with  
low or medium user interaction.  
For security demonstration or to reproduce the vulnerability follow  
the provided information and steps below to continue.  
  
  
PoC: Create New File and Edit a file (CMD_FILE_MANAGER)  
<form name=info action='https://address:port/CMD_FILE_MANAGER' method='POST'>  
<input type="hidden" name=action value="edit">  
<input type="hidden" name=path value="/index.php">  
<input name="hidden" value="<? phpinfo ?>">  
<input type="submit" value="save as">  
<input type="hidden" name=filename value="/index.php">  
</form>  
  
  
Security Risk:  
==============  
The security risk of the client-side cross site request forgery web  
vulnerability in the web-application is estimated as medium. (CVSS  
3.0)
