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>
