Subject: [OSSA 2012-019] Extension of token validity through token chaining
(CVE-2012-5563)
-----BEGIN PGP SIGNED MESSAGE-----
Hash: SHA256
OpenStack Security Advisory: 2012-019
CVE: CVE-2012-5563
Date: November 28, 2012
Title: Extension of token validity through token chaining
Reporter: Anndy
Products: Keystone
Affects: Folsom, Grizzly
Description:
Anndy reported a vulnerability in token chaining in Keystone. A token
expiration date can be circumvented by creating a new token before the
old one has expired. An authenticated and authorized user could
potentially leverage this vulnerability to extend his access beyond the
account owner expectations. Note: this vulnerability was fixed in the
past (CVE-2012-3426) but was reintroduced in Folsom when code was
refactored to support PKI tokens.
Grizzly (development branch) fix:
https://github.com/openstack/keystone/commit/38c7e46a640a94da4da89a39a5a1ea9c081f1eb5
Folsom fix (included in upcoming Keystone 2012.2.1 stable update):
https://github.com/openstack/keystone/commit/f9d4766249a72d8f88d75dcf1575b28dd3496681
