Sulu is a highly extensible open-source PHP content management system based on the Symfony framework. There is an issue when inputting HTML into the Tag name. The HTML is executed when the tag name is listed in the auto complete form. Only admin users can create tags so they are the only ones affected. The problem is patched with version(s) 2.4.16 and 2.5.12.
The product receives input from an upstream component, but it does not neutralize or incorrectly neutralizes special characters such as "<", ">", and "&" that could be interpreted as web-scripting elements when they are sent to a downstream component that processes web pages.
The product does not neutralize or incorrectly neutralizes user-controllable input before it is placed in output that is used as a web page that is served to other users.
