There are packages installed that are affected by a vulnerability referenced in the following CVE:

  - 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. (CVE-2020-12692)

The remote Redhat Enterprise Linux 8 host has packages installed that are affected by multiple vulnerabilities as referenced in the RHSA-2020:3105 advisory.

    The OpenStack Identity service (keystone) authenticates and authorizes     OpenStack users by keeping track of users and their permitted activities.
    The Identity service supports multiple forms of authentication, including     user name and password credentials, token-based systems, and AWS-style     logins.

    Security Fix(es):

    * EC2 and credential endpoints are not protected from a scoped context     (CVE-2020-12689)

    * OAuth1 request token authorize silently ignores roles parameter     (CVE-2020-12690)

    * Credentials endpoint policy logic allows changing credential owner and     target project ID (CVE-2020-12691)

    For more details about the security issue(s), including the impact, a CVSS     score, acknowledgments, and other related information, refer to the CVE     page listed in the References section.

The remote Ubuntu 18.04 LTS host has packages installed that are affected by multiple vulnerabilities as referenced in the USN-4480-1 advisory.

    It was discovered that OpenStack Keystone incorrectly handled EC2 credentials. An authenticated attacker     with a limited scope could possibly create EC2 credentials with escalated permissions. (CVE-2020-12689,     CVE-2020-12691)

    It was discovered that OpenStack Keystone incorrectly handled the list of roles provided with OAuth1     access tokens. An authenticated user could possibly end up with more role assignments than intended.
    (CVE-2020-12690)

    It was discovered that OpenStack Keystone incorrectly handled EC2 signature TTL checks. A remote attacker     could possibly use this issue to reuse Authorization headers. (CVE-2020-12692)
