Credits: Raphael Geissert <atomo64@...il.com>
Release date: 2008-10-27
Affects: v0.9 [23-Jul-2008]

    * Demo: http://phpmyid.com

Background:
    phpMyID is a single user OpenID identity provider implemented in PHP.

Problem description:
    The MyID.php script does not sanitize the input it is supposed to be given
    by the site where the user wants to be authenticated. When the site would
    try to know whether the user is authenticated at the identity provider, and
    the identity does not exist, the user would be redirected to whatever site
    is specified (or inject headers, when php << 4.4.2 or php >= 5 && << 5.1.2).

Impact:
    A user can be tricked and redirected to its vulnerable identity provider,
    place where the user will be redirected (and/or headers will be injected).

Example exploit:
    MyID.php?openid_return_to=http://www.ecocho.com&openid_mode=checkid_immediate
