OpenStack Security Advisory: 2013-014 CVE: CVE-2013-2104 Date: May 28, 2013 Title: Missing expiration check in Keystone PKI tokens validation Reporter: Eoghan Glynn (Red Hat), Alex Meade (Rackspace) Products/Affects: Keystone (Folsom only), python-keystoneclient (0.2.0+) Description: Eoghan Glynn from Red Hat and Alex Meade from Rackspace both reported a vulnerability in expiry checks for PKI tokens in the Keystone authentication middleware. Expired tokens for authenticated users could continue to be used, potentially resulting in the bypass of intended security policies. The effect of PKI token revocation is also reversed when the token expires, in the sense that a revoked token is once again treated as being valid. Only setups using PKI tokens are affected. Note: The affected code was added to Keystone in the Folsom release, but was moved to python-keystoneclient during the Grizzly development cycle. python-keystoneclient fix (will be included in upcoming 0.2.4 release): https://review.openstack.org/#/c/30742/ Keystone (Folsom) fix: https://review.openstack.org/#/c/30743/ References: https://bugs.launchpad.net/python-keystoneclient/+bug/1179615 http://www.cve.mitre.org/cgi-bin/cvename.cgi?name=2013-2104
