CVE-2013-4294 is a vulnerability of currently unknown severity. The (1) mamcache and (2) KVS token backends in OpenStack Identity (Keystone) Folsom 2012.2.x and Grizzly before 2013.1.4 do not properly compare the PKI token revocation list with PKI tokens, which allow remote attackers to bypass intended access restrictions via a revoked PKI token.. EPSS estimates a 2.34% chance of exploitation in the next 30 days.
