CVE-2015-7546 [HIGH] CVE-2015-7546 openstack-keystone: Improper check of tampered revocated PKI/PKIZ token
CVE-2015-7546 openstack-keystone: Improper check of tampered revocated PKI/PKIZ token
It was reported that when the PKI or PKIZ token providers are used, it is possible for an attacker to manipulate the token contents of a revoked token such that the token will still be considered to be valid. Identity service checks it by searching for a revocation by the entire token. It is possible for an attacker to manipulate portions of an intercepted PKI or PKIZ token that are not cryptographically protected, which will cause the revocation check to improperly consider the token to be valid. This can allow unauthorized access to cloud resources if a revoked token is intercepted by an attacker.
Users are recommended to not use PKI or PKIZ token providers and to switch to using another supported tok
