DESCRIPTION:
Darren McDonald has reported some weaknesses and two vulnerabilities
in One Click Orgs, which can be exploited by malicious users to
potentially cause a DoS (Denial of Service), manipulate certain data,
and conduct spoofing and script insertion attacks and by malicious
people to disclose sensitive information and conduct spoofing
attacks.

1) The application does not properly verify email addresses when a
user changes his email address. This can be exploited to appear to be
voting as a different user or to prevent a user from logging in by
choosing another user's email address if the malicious user joined
before the victim.

2) Input passed to the "return_to" parameter is not properly verified
before being used to redirect users. This can be exploited to redirect
users to arbitrary web sites.

3) An error within the "Reset your password" functionality can be
exploited to enumerate email addresses of users.

4) Input passed via the "Description" field of a new vote and eject
member proposal is not properly sanitised before being used. This can
be exploited to insert HTML and script code, which will be executed in
a user's browser session in context of an affected site if malicious
data is viewed.

5) Certain input passed via the email address of a user is not
properly sanitised before being used in SMTP messages. This can be
exploited to modify SMTP messages and e.g. send spam emails.

The weaknesses and vulnerabilities are reported in version 1.2.1.
Other versions may also be affected.

SOLUTION:
Update to version 1.2.3.
