Description |
Gelato CMS contains a flaw that allows a remote cross site scripting attack. This flaw exists because the application does not validate the content variables upon submission to the comments.php script. This could allow a user to create a specially crafted URL that would execute arbitrary code in a user's browser within the trust relationship between the browser and the server, leading to a loss of integrity. |

Solution |
As of now, there is no vendor patch. It is recommended that comments be turned off for the moment. If comments are absolutely essential, then a quick work around would be to encode the comment before it goes into the database. In the file /[gelato-root]/admin/comments.php, add the following line " $_POST["content"] = htmlspecialchars($_POST["content"],ENT_QUOTES);". This should be added before the line: " if ($comment->addComment($_POST)) {header("Location:......." Around line 44 or thereabouts. |
