IMPACT:
Cross Site Scripting

SOFTWARE:

http://secunia.com/product/17018/

DESCRIPTION:
Hanno Böck has reported a vulnerability in the My Calendar plugin for
Serendipity, which can be exploited by malicious people to conduct
cross-site request forgery attacks.

The vulnerability is caused due to the application allowing users to
perform certain actions via HTTP requests without performing any
validity checks to verify the request. This can be exploited to e.g.
conduct script insertion attacks against the blog-page.

The vulnerability is reported in version 0.12. Prior versions may
also be affected.

SOLUTION:
Update to version 0.13.
