DESCRIPTION:
A vulnerability has been discovered in MODx, which can be exploited
by malicious people to conduct cross-site request forgery attacks.

The vulnerability is caused due to MODx allowing users to perform
certain actions via HTTP requests without performing proper validity
checks to verify the requests. This can be exploited to e.g. create
an user when a logged-in administrator visits a specially crafted web
page.

Successful exploitation of this vulnerability requires the
"HTTP_MODAUTH" parameter or "modAuth" header to be set to the valid
$site_id that is specific for the respective application deployment.

The vulnerability has been confirmed in version 2.0.8-pl. Other
versions may also be affected.

SOLUTION:
Do not browse untrusted sites or follow untrusted links while being
logged-in to the application.
