http://www.majorsecurity.de/index_2.php?major_rls=major_rls37

Introduction
============
HolaCMS is a Content Management System.

More Details
============
Cross Site Scripting:
Input passed directly to the "acuparam" parameter in "index_cms.php" is not properly sanitised before being returned to the user.
This can be exploited to execute arbitrary HTML and script code in a user's browser session in context of an affected site. 

Workaround
=============
Edit the source code to ensure that input is properly sanitised.
You should work with "htmlspecialchars()" or "htmlentities()" php-function to ensure that html tags
are not going to be executed. 

Example:
$pass = htmlentities($_POST['pass']);
$test = htmlspecialchars($_GET('test'));
?>
