Official description
A flaw was found in the openstack-tripleo-common component of the Red Hat OpenStack Platform (RHOSP) director. This vulnerability allows an attacker to deploy potentially compromised container images via disabling TLS certificate verification for registry mirrors, which could enable a man-in-the-middle (MITM) attack.
Source: the CVE record as published by its numbering authority, via NVD and CVE.org.
The underlying weakness: Improper Certificate Validation
The product does not validate, or incorrectly validates, a certificate.
How developers prevent this class of flaw
- Certificates should be carefully managed and checked to assure that data are encrypted with the intended owner's public key.
- If certificate pinning is being used, ensure that all relevant properties of the certificate are fully validated before the certificate is pinned, including the hostname.
