Описание
An issue was discovered in OpenStack Keystone before 15.0.1, and 16.0.0. The EC2 API doesn't have a signature TTL check for AWS Signature V4. An attacker can sniff the Authorization header, and then use it to reissue an OpenStack token an unlimited number of times.
A flaw was found in Keystone, where the restriction was not checked for the Signature Version 4 (V4) process of AWS signatures issued within a limited time window. This flaw allows an attacker to capture an auth header and reuse it, potentially maintaining indefinite access.
