TITLE:
MyBB Multiple Vulnerabilities

SECUNIA ADVISORY ID:
SA39378

VERIFY ADVISORY:
http://secunia.com/advisories/39378/

DESCRIPTION:
Some vulnerabilities have been reported in MyBB, which can be
exploited by malicious people to conduct cross-site request forgery
attacks and bypass certain security restrictions.

1) The password reset functionality relies on an insecure random
number generator to create password reset tokens. This can
potentially be exploited to guess a generated token or password.

Note: Successful exploitation may require that PHP processes are
reused by the webserver.

2) Certain input passed via the URL to the password reset
functionality is not properly sanitised before being used, which can
be exploited to e.g. inject a "BCC:" header to the password reset
email by tricking a user into following a specially crafted link.

3) The application allows users to perform certain actions via HTTP
requests, without performing any validity checks to verify the
request. This can be exploited by tricking a user into visiting a
malicious site.

SOLUTION:
Update to version 1.4.12.
