DESCRIPTION:
Jakub Galczyk has discovered a vulnerability in concrete5, which can
be exploited by malicious people to conduct cross-site scripting
attacks.

Input passed via the "approveImmediately" parameter to
index.php/tools/required/edit_collection_popup.php (when "ctask" is
set to "edit_metadata") is not properly sanitised in
concrete/elements/collection_metadata.php 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.

The vulnerability is confirmed in version 5.5.2.1. Other versions may
also be affected.

SOLUTION:
Edit the source code to ensure that input is properly sanitised.

PROVIDED AND/OR DISCOVERED BY:
Jakub Galczyk.
