OpenStack Keystone 15.0.0 and 16.0.0 is affected by Data Leakage in the list credentials API. Any user with a role on a project is able to list any credentials with the /v3/credentials API when enforce_scope is false. Users with a role on a project are able to view any other users' credentials, which could (for example) leak sign-on information for Time-based One Time Passwords (TOTP). Deployments with enforce_scope set to false are affected. (There will be a slight performance impact for the list credentials API once this issue is fixed.)

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

  - OpenStack Keystone 15.0.0 and 16.0.0 is affected by Data Leakage in the list credentials API. Any user
    with a role on a project is able to list any credentials with the /v3/credentials API when enforce_scope
    is false. Users with a role on a project are able to view any other users' credentials, which could (for
    example) leak sign-on information for Time-based One Time Passwords (TOTP). Deployments with enforce_scope
    set to false are affected. (There will be a slight performance impact for the list credentials API once
    this issue is fixed.) (CVE-2019-19687)

The remote Redhat Enterprise Linux 8 host has packages installed that are affected by a vulnerability as referenced in the RHSA-2019:4358 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):

    * Credentials API allows non-admin to list and retrieve all users     credentials (CVE-2019-19687)

    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.

Tenable has extracted the preceding description block directly from the Red Hat Enterprise Linux security advisory.

Note that Nessus has not tested for this issue but has instead relied only on the application's self-reported version number.

Daniel Preussker discovered that OpenStack Keystone incorrectly handled the list credentials API. A user with a role on the project could use this issue to view any other user's credentials.

Note that Tenable Network Security has extracted the preceding description block directly from the Ubuntu security advisory. Tenable has attempted to automatically clean and format it as much as possible without introducing additional issues.
