@keystone-core: please validate the latest patches
@anndy: do you have a full name (and optionally company) that we can credit for the discovery of this vulnerability ?
Proposed impact description:
Title: Extension of token validity through token chaining
Reporter: $CREDIT
Products: keystone
Affects: Folsom
Description:
$CREDIT 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 UUID tokens.
