Fixed impact description:
Title: Extension of token validity through token chaining
Reporter: Anndy
Products: Keystone
Affects: Folsom
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.
