#vulnerability

A cross-site scripting vulnerability has been discovered in the TreeDropdownField and TreeMultiSelectField. This vulnerability can only be exploited if a user with CMS access has posted malicious or unescaped HTML into any of the dataobjects used as a data source for either of these fields. This has been resolved by ensuring that all dataobjects used as a data source have their content safely encoded.

A low level vulnerability has been found in the SilverStripe framework, where the Quadratic Blowup Attack could potentially be exploited to affect the performance of a site. See http://mashable.com/2014/08/06/wordpress-xml-blowup-dos/ for a writeup.

Non IE browsers don’t appear to be affected, but I haven’t tested a wide range of browsers to be sure Requests that come through from IE do NOT appear to encode all entities in the URL string, meaning they are inserted into output content directly by SSViewer::process() when rewriting hashlinks, as it directly outputs $_SERVER[‘REQUEST_URI’] **Example IE8 request** 127.0.0.1 - - [18/Jun/2014:14:13:42 +1000] “GET /site/cars/brands/toyota?one=1\”onmouseover=\”alert(‘things’);\” HTTP/1.1” 200 **Example FF request** 127.0.0.1 - - [18/Jun/2014:14:14:22 +1000] “GET /site/cars/brands/toyota?one=1\%22onmouseover=\%22alert(%27things%27);\%22 HTTP/1.1” 200 This causes any hash anchor to have the JS code inserted into the page as-is.

A number of form actions in the Forum module are directly accessible. A malicious user (e.g. spammer) can use GET requests to create Members and post to forums, bypassing CSRF and anti-spam measures. Additionally, a forum moderator could be tricked into clicking a specially crafted URL, resulting in a topic being moved. Thanks to Michael Strong for discovering.
