DESCRIPTION:
Stefan Schurtz has discovered a vulnerability in Contao, which can be
exploited by malicious people to conduct cross-site scripting attacks.


Certain input passed to the URL after index.php to the frontend is
not properly sanitised in the "getPageIdFromURL()" function in
system/modules/frontend/Frontend.php before being returned to the
user when the automatic URL construction feature is used (e.g.
"Article Teaser"). This can be exploited to execute arbitrary HTML
and script code in a user's browser session in context of an affected
site.

The vulnerability is confirmed in version 2.10.1. Prior versions may
also be affected.

SOLUTION:
Update to version 2.10.2.
