DESCRIPTION:
A vulnerability has been reported Serendipity, which can be exploited
by malicious people to conduct cross-site request forgery attacks.

The vulnerability is caused due to the Entry Manager allowing users
to perform certain actions via HTTP requests without performing any
validity checks to verify the user's request. This can potentially be
exploited to perform certain actions on the Entry Manager page without
the user's knowledge.

The vulnerability has been reported in versions prior to 1.0-beta3.

Note: An error which allows the administrative user to inject PHP
code into the "serendipity_config_local.inc.php" file has also been
fixed.

SOLUTION:
The vulnerability has been fixed in version 1.0-beta3.

PROVIDED AND/OR DISCOVERED BY:
The vendor credits Geoff Johnson.
