DESCRIPTION:
High-Tech Bridge SA has discovered a vulnerability in Open Blog,
which can be exploited by malicious people to conduct cross-site
request forgery attacks.

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. assign a user administrative
privileges or change an administrator's password by tricking a logged
in administrative user into visiting a malicious web site.

NOTE: This may further be used to conduct script insertion attacks.

The vulnerability is confirmed in version 1.2.1. Other versions may
also be affected.

SOLUTION:
Do not browse untrusted websites or follow untrusted links while
logged in to the application.
