  1)Introduction
  PlumeCMS is a "Versatile Content Management System in PHP on top of MySQL".
  
  2)Vulnerability Description
  PlumeCMS 1.2.4 (and below) is prone to multiple peristent XSS vulnerability due to an improper input sanitization of multiple
  parameters.
   2.1 "u_email" parameter
   "u_email"parameters is not correctly sanitized before being passed to server side script "manager/users.php" via http POST 
   method. An attacker - who is able to change his profile settings - could insert malicious code into "Email" field
   - within "Authors" template - in order to create a persistent XSS vulnerability for all user/admin who access to Plume's 
   management interface.
   
   2.2 "u_realname" parameter
   "u_realname" parameter is not correctly sanitized before being passed to server side script "manager/users.php" via http POST 
   method. An attacker - who is able to change his profile settings - could insert malicious code into "Name" field
   - within "Authors" template - in order to create a persistent XSS vulnerability for all user/admin who access to Plume's 
   management interface.
  
   2.3 "c_author" parameter
   An unauthenticated user could insert html/javascript code in "Author" field within "ADD A COMMENT" section - which is present
   in every web page - due to an incorrect sanitization of "c_author" parameter. This will produce a Persistent XSS vulnerability
   for all user/admin who will click on "Comments" tab within Plume's administration interface. 
  
  3)Exploit 
   3.1 Exploit "u_email" parameter
   Insert the following code in "Email" field within "Authors" template under "manager/users.php?user_id=<user_id>":
   <script>alert("xss")</script>
  
   3.2 Exploit "u_realname" parameter
   Insert the following code in "Name" field within "Authors" template under "manager/users.php?user_id=<user_id>":
   <script>alert("xss")</script>
  
   3.3 Exploit "c_author" parameter
   Insert the following code in "Author" field within "ADD A COMMENT" section":
   <script>alert("xss")</script>
