  The vulnerable code is in the Minishop 1.5 plugin on the Admin_Minishop.php
  , after installing it give to any user right to edit the minishop, then
  this user can inject arbitrary javascript code whenusing add product or
  add category(both options can trigger the XSS) in the name field typing
  <script>alert('XSS');</script>
  
  As you can see data is not sanitize :)
  function AddCategory()
  {
  require('Language.php');
  echo '<b>' . $Mtxt['Add Category'] .'</b><br>';
  $ca = & $_REQUEST['cat'];
  $cat = $this->my_replace($ca, "no");
  $catdes = & $_REQUEST['catdesc'];
  $catdesc= $this->my_replace($catdes, "yes");
  $Category = $this->GetCategories();
  
  if (empty($cat) )
  {
  echo '<table class="bordered"><br>';
  echo '<th>Category</th><th>Description</th>';
  echo '<form action="Admin_Minishop?cmd=addcat"><br>' ;
  echo '<tr><td><input type="text" name="cat" size="10" value="'
  . $cat . '"></td>';
  echo '<td><input type="text" name="catdesc" size="30" value="'
  . $catdesc . '"></td></tr>';
  echo '<input type="hidden" name="cmd" value="addcat"><br>';
  echo '</table><br>';
  echo '<input type="submit" value="' . $Mtxt['Add Category'] .
  '">';
  
  }
  else
  {
  $Category[$cat] = $catdesc;//echo 'Debug:' .
  var_dump($Category) .':';
  $this->SaveCategories($Category);
  }
  }
