Published Dec 9, 2019CWE-522EPSS 1.78%

Overview

CVE-2019-19687 is a high-severity vulnerability. It was published on December 9, 2019 and has a CVSS 3.1 base score of 8.8 (HIGH).

This vulnerability has a CVSS 3.1 base score of 8.8, rated HIGH. It can be exploited remotely over the network. Some level of privileges is required for exploitation.

Technical description

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.)

Remediation

Check the references section for vendor advisories, patches, and mitigation guidance. If immediate patching is not possible, review the CVSS vector to understand the attack surface and apply compensating controls such as network segmentation or access restrictions.
