DESCRIPTION:
luny has discovered a vulnerability in Some Chess, 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 POST requests without performing any
validity checks to verify the user's request. This can be exploited to
change a user's username and password.

Note: This can also be exploited to execute arbitrary HTML and script
code in a user's browser session in context of an affected site due to
the unsanitised "user" form field parameter in menu.php.

The vulnerability has been confirmed in version 1.5rc2. Other
versions may also be affected.

SOLUTION:
Use another product.
