DESCRIPTION:
Two vulnerabilities have been reported in the Activity module for
Drupal, which can be exploited by malicious users to conduct script
insertion attacks and by malicious people to conduct cross-site
request forgery attacks.

1) Input passed via the module settings is not properly sanitised
before being used. This can be exploited to insert arbitrary HTML and
script code, which will be executed in a user's browser session in
context of an affected site when the malicious data is being viewed.

Successful exploitation of this vulnerability requires the "access
administration pages" and "administer activity" permissions.

2) The application allows users to perform certain actions via HTTP
requests without performing any validity checks to verify the
requests. This can be exploited to e.g. remove an activity by
tricking a logged in user into visiting a malicious web site.

The vulnerabilities are reported in versions 6.x-1.x.

SOLUTION:
Fixed in version 6.x-2.0-alpha1.

PROVIDED AND/OR DISCOVERED BY:
The vendor credits Ivo Van Geertruyen, Drupal Security Team and
Justin Klein Keane.
