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 -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.4.9 (GNU/Linux) iEYEARECAAYFAkjeok8ACgkQYy49rUbZzlp5fQCffp1xO3Ox3cZmbmRKR+yRIfzX 9jEAn1xz7fMhQVX4DtmO2WOUPA8gafyU =fwM6 -----END PGP SIGNATURE-----
