Multiple vulnerabilities have been reported in MODx, which can be exploited by malicious people to conduct clickjacking and cross-site scripting attacks.
1) Input passed via the "editor" and "type" GET parameters to /manager/media/browser/mcpuk/browser.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.
2) Certain input passed to /assets/snippets/jot/jot.class.inc.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.
3) The application allows users to perform certain actions via HTTP requests via iframes without performing any validity checks to verify the requests. This can be exploited to perform certain unspecified actions by tricking a user into e.g. clicking a specially crafted link via clickjacking.
The vulnerabilities are reported in versions prior to 1.0.15.
