DESCRIPTION:
A vulnerability has been discovered in Public Knowledge Project Open
Journal Systems and Open Conference Systems, 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. upload PHP files by tricking
a logged in administrator into visiting a malicious web site.

The vulnerability is confirmed in Open Journal Systems version 2.3.6
and Open Conference Systems version 2.3.4. Other versions may also be
affected.

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